Gaming machines, or slots, are an integral part of brick-and-mortar and online casinos. Their main advantage is simplicity and a wide range of available bonuses. You can have a go even if you are a complete beginner and don't know much about this world of gambling.

However, if you want to achieve stable results and increase your chances of winning, you will have to work on your game strategy. This includes a wide set of skills, from understanding the game to bankroll management to effective use of bonuses. Its creation will not be easy at first, and that is why we have written a small guide for you, which will guide you through the complete basics, as well as various tips and tricks.

Basic principles of slots

If you want to immerse yourself in the world of slot machines and earn winnings while you’re at it, you will first need to understand them. You need to know how slot machines work and what affects the winnings themselves. Let's first look at the basic concepts.

Random number generator (RNG)

Randomness is important for a fair and independent game, and that's when RNG comes into play. It is a random number generator that takes the form of a complex algorithm that generates thousands or even millions of different number combinations during gameplay. Based on them, the reels on the machine then stop.

To ensure fairness, RNG is regularly audited by third parties who verify that the generation of numbers is not influenced by the casino in any way - these are usually independent companies that specialize in gambling.

Volatility and Return to Player (RTP)

Two other terms are important to understanding how slots work, namely volatility and Return to Player (RTP). The first term determines how often and how high the winnings are paid out by the slot machine. You can meet slot machines with low, medium and high volatility.

It should be noted that the given value is calculated from the total volume of bets and thus does not apply to individual games. If you choose a slot that has low volatility, it means that it often pays out low amounts in the long run.

Conversely, a slot machine with high volatility will pay out high amounts, but the chance of winning will be low. If you want to have a high chance of winning and avoid high losses, it will be better for you to choose slot machines with low or medium volatility.

Return to Player (RTP) in turn indicates the return of the bet to the player. Again, this is a long-term indicator that should be taken with a grain of salt. However, in general, it is good to look for slots with a high RTP. Its value is always given as a percentage and is calculated based on RNG and average spin results over the long term.

When you come across a slot machine with 95% RTP, it should theoretically pay out CZK 95 for every CZK 100 bet. You cannot be sure of this ratio working out for every game, but compared to slot machines with a lower RTP, the ratio of the bet paid out will be higher. To begin with, you just need to know that the higher the RTP, the more money you will get from the bet in the event of a win.

Each slot machine is unique and has its own parameters that affect the game. That is why it is important to look up all available information regarding it before playing. This info is always available on the website of the given online casino. You will see its volatility and RTP, but also what combinations need to be achieved in order to get a win.

Budget and bankroll management

Now that you know how slot machines work, you can start creating your first game strategy. The first step is planning your bankroll, or player budget, with which you will play. It is the control you’re your finances that is key when gambling and will help you avoid losing extremely large sums, which could eventually have an adverse impact on other areas of your life.

At the very beginning, set aside funds that you can afford to lose. If you only have money in your account for paying your rent, it is not the best idea to bet it all right away in an online casino.

During the game itself, set the maximum amount of bets that you will allow yourself to play with. Be prepared for the game to tempt you to raise your bets, which will in turn expose you to a higher risk. It is much better to set a specific amount that you will not exceed.

In this regard, the determination of the maximum loss is also important. Know in advance how much money you can afford to lose in a given period. Set a realistic goal that will match your ambitions while not affecting your financial health.

In addition to the budget, also set time limits that you will adhere to while playing. Specifically, determine how long your gaming sessions will be and, if necessary, set how often you will take breaks - it is ideal to take a break of around 10 to 20 minutes after an hour of playing.

Use of bonuses and promo offers

Your strategy for playing slot machines should also include casino bonuses, promotions or loyalty programs. Familiarize yourself with the individual types of bonuses and how they work. You will commonly encounter:

registration bonuses,

bonuses for placed bets,

free spins,

cashback bonuses.

You can then start looking for suitable bonuses that you can use while playing. The most attractive for you will be free spins, which you can get for placing a bet, but also as a reward for activity at the given online casino. Find out beforehand what bonuses the casino offers and how you can get them.

It will be much easier for you to plan your strategy, which includes, for example, bonuses for placed bets and free spins. Also, keep in mind that most cash bonuses will come with wagering requirements. These indicate how large a volume of bets you will have to make in order to withdraw the bonus from the game account. Sometimes it can be ten times the amount of the bonus, which may not suit you, especially with a smaller bankroll.

All information about bonuses and their rules are listed directly on the online casino page. You can read from them not only which conditions you have to fulfill, but also by when you have to do so. Some casinos will also offer you various loyalty programs, thanks to which, for example, they will assign you a certain number of free spins every month or provide you with exclusive bonuses for registered players.

What betting strategies are there?

Last but not least, it is good to pay attention to your betting strategy, through which you will be able to maximize your winnings and at the same time minimize any losses. You can choose your own approach - we will discuss some of them in more detail below.

The Martingale system

The whole strategy is based on doubling the bets after each losing game. The goal is to offset the accumulated loss with the next win, which may not come. In practice, you can easily make up all your loss, but on the other hand, it can quickly happen that you completely exhaust your bankroll and the loss remains. When playing slots, this approach is rather disadvantageous.

The Reverse Martingale (Paroli)

This strategy is the complete opposite of the Martingale system. In this case, you double your bets only after a win. Compared to the previous strategy, this is a much safer way of playing, with which you do not unnecessarily expose yourself to a high risk. Unfortunately, no one can guarantee you any winnings, and again you can only end up with a loss. But it will not be as high as with the Martingale system.

If you still want to start this strategy, start with smaller bets. In addition, if you manage to achieve a win that exceeds the amount of the maximum bet, you can bet the maximum amount and thus reinvest the winnings. At the same time, it is better to bet on more game lines, which will increase your chance of winning even more.

The Smart Gambler

The Smart Gambler strategy works in a similar way to the reverse martingale. In essence, this is a modified version of it, where you choose a slot machine with the possibility of doubling your winnings using the Gamble button. At first, you will only bet small amounts until you hit a winning combination.

If you land a win, you can start doubling it until you win a satisfactory amount. If you lose, stop doubling your winnings and start betting low again. In some cases, the machine itself may prohibit you from increasing your bets several times.

This strategy offers one of the highest payouts compared to others, making it widely popular among players. In the first step, choose how long you want to play the machine and divide the time by the average length of the game round - the standard average is between 4 and 6 seconds.

This will give you the number of rounds you will complete as part of the strategy. After that, it is time to determine the budget, which you divide by the number of bikes, and thus you get the budget for one bike. You can immediately start betting this amount until you win - then you double the bet.

Flat Betting

In this case, you always bet the same amount, regardless of the results of the individual rounds. So you do not adjust bets after a loss or after a win. Again, this is a safer strategy, with which you avoid high risk and loss. On the other hand, you will slightly reduce your chances of a higher win.

Vabank's Strategy

With Vabank, you bet your entire bankroll on one game. In practice, this is one of the riskiest approaches, which can bring you an extremely high win, but also a big loss. Since you bet your entire budget on only one line, be prepared to lose your bet with a high probability.

However, if you are looking for an adrenaline rush, the Vabank strategy may be right for you. With most machines, you can gradually reduce the number of lines you bet on, allowing you to limit the maximum bet. It is not an exception that the maximum bet goes up to 100 dollars.

When choosing a slot machine, pay attention to the amount of the maximum win. This can be lower than the potential win you can get when betting on one line. So always read all terms and conditions carefully. But your chances of winning are really low, so don't play with this strategy if you don't have the relevant budget.

Constant Betting Strategy

Constant Betting Strategy is among the safest, which makes it especially suitable for cautious players who don't want to get into any big action. On the other hand, it will bring you very low winnings, if any. This strategy is simple, you set the time for which you will play, choose the amount of the bet and start playing.

You will not increase or decrease the set bet, regardless of whether you win or lose. In this way, you will avoid sudden emotional decisions that can deepen your loss even more.

Progressive Betting Strategy

In this case, you gradually increase your bets when you win and decrease them when you lose. Compared to other strategies, this is the only approach that tries to balance possible wins and losses as much as possible. Such an approach is more demanding and requires detailed planning, which may be a bit of a pain for you at first.

Your Mom's strategy

The last and funny strategy is Your Mom's Strategy, which is one of the easiest. Just follow your mom’s advice, who would very likely not recommend that you play slot machines. You have nothing to lose, but nothing to gain either. If you want to completely avoid risk and losing your budget, this strategy is definitely the most effective.

If you want to start playing slots, first familiarize yourself with how they work and all the features they offer. Immediately after that, you can start creating your first strategy. During it, focus not only on your bankroll, but also on various restrictions associated with the maximum loss or amount of bets. In any case, pay attention to your safety first and try to avoid unnecessarily large risks at first.

Like to let off some steam in online casinos from time to time? Then, with every spin, you might wonder how the whole mechanism actually works. The truth is that slot machines still run on a similar principle as they once did, but their appearance has changed significantly in the more than 100 years of their existence.

Slot machines have come a long way

The first slots from the late 19th century were purely mechanical, with players turning the drums and reels using a manual lever. In 1894, Charles Frey came up with the important invention of automatic payout and also with the five basic playing symbols, which were diamonds, spades, hearts, horseshoes and the liberty bell.

At the beginning of the 20th century, players faced a challenging period riddled with restrictions, and the first electromechanical slot machine was created as late as in 1964. The reels of this slot had an electric drive and the lever could be dropped.

The popular video slots came along in 1976 and first appeared in Las Vegas. However, the online casinos we know today began to develop from 1994, when developers began creating sophisticated machines controlled by microprocessors. These have a lot of advanced features, from calculating the average bet volume to tracking odds.

Basic principles and division of slot machines

Playing on slot machines is relatively simple, which is why this type of gambling is so popular. Today, their reels work electronically and are controlled by software that stops spinning at a certain moment at the player's prompt. Since most of them are played for money, they are subject to strict regulations and can only be placed in licensed gaming rooms and casinos.

Slot machines can be divided into mechanical, digital and video slots. You will no longer encounter mechanical machines, at most in museums or retro arcades, but digital slots are still very popular and you can find them in casinos all over the world. The best thing about video lotteries is that they are connected to the entire network of machines and are played for the jackpot. A separate category are those in online casinos that you can play on your computer or smartphone.

RNG as the heart of the slot machine

The software device in slot machines can be referred to Random Number Generator or RNG. So whether you play slots, roulette or blackjack, this mechanism monitors all moves. And because it is based on random results, it no longer applies that players most often used to win when the machine was full of loose change and needed to empty out.

Nowadays, everyone plays according to the same rules and the probability of winning is not affected by previous results, the current jackpot or the frequency of bets. Stories of overtly benevolent machines overflowing with money are but a false tale. Just watch out for scammers and always check the credibility of the establishment.

You can read more about RNG in our article: What is RNG?

Payout Ratio or RTP

The calculation of the probability of winning is denoted by the RTP or Return to Player. This return or payout share is given by a theoretical value that is based on mathematical probability. This means that the larger the amount you spin, the closer you should get to the given value.

So RTP is the ratio of money that is returned to the players, so it is usually given as a percentage - we focused on the subject of RTP in more detail in this article.

Just be careful that it is based on the bet, not the turnover. But you don't have to worry about complex mathematics, current slots usually have this information listed in the game plans. But there are those math whizzes who want to check whether the numbers really correspond to reality.

Volatility of slot machines

But volatility, which you may know from the world of finance, also comes into play. And in the world of gambling, it has a similar meaning. The higher the volatility, the more you can win, but you also wait longer for your return. In contrast, slots with low volatility do not offer such high winnings, but you will score points on them more often. It therefore depends solely on you, if you prefer an adrenaline rush, or if you are willing to settle for lower amounts without the risk.

Symbols and winning combinations

All seasoned players know the traditional symbols that are based on card symbols. These include hearts, spades and diamonds. Bells, which have a long history, are also widely used. On one of the first slot machines from 1894, its author, Charles Frey, used images of green bells that marked the main win. Since the 20th century, lucky sevens, fruit trees, gum and other symbols have also been used - you can read more about symbols in the article Symbols on slot machines – why to get acquainted?

In addition to the standard symbols, there are also wild or scatter symbols. The so-called Wild symbol can be found on most slot machines in brick-and-mortar casinos and online, and it is there to replace other symbols and enliven the entire game. The only symbol it cannot replace is the scatter symbol, because it also brings various useful functions – for example, it triggers bonus games and helps create new winning combinations.

Bonus games and features

In addition to all this, wild symbols can have various modifications. Some are expanding, others are sliding, which means that they also reach other positions on the winning field or are applied in the next round. And another popular bonus is, of course, free spins, where you get to spin for free. You will also enjoy the multiplication functions or the purchase of symbols, all of which make the game more exciting. This article discusses how you can get bonuses and make the most of them.

Modern trends and innovations in slot machines

Online casinos, which you can access in a few seconds directly from your mobile phone, are a common phenomenon these days. However, current technologies go even further and offer experiences similar to visiting Las Vegas even while playing in a digital environment. The key to this is virtual reality, which makes you feel like you are playing real slots. According to experts, this is exactly the direction casinos will continue to take in the future. And hand in hand with that go virtual currencies and other new age developments.

As you can see, the era of slot machines is far from over. The gambling phenomenon that can adapt to any conditions is constantly changing and evolving. So you can try new games and trends at any moment, and you certainly have something to look forward to in the future.

RNG denotes a Random Number Generator, i.e. a process in which sequences of numbers are generated at random. They do not follow any formula or system and are not influenced by external circumstances. RNG can therefore be used, for example, in computer simulations, in various types of modeling or in gambling. This applies to roulette and blackjack, as well as to slot machines.

Concept and definition of RNG

An RNG generator is a type of microprocessor that generates hundreds of random number sequences in just one second, producing billions of combinations in total. Many current technologies, including gaming machines, employ such an algorithm. Just be aware of the difference between true and pseudo-random random number generators.

A true random number generation is, for example, rolling dice or drawing lots. But if we want to apply this principle in programming, we need special hardware, which is available only to a few military and commercial institutions that work with strictly secured systems.

In most cases, so-called pseudo-random numbers are sufficient. Their sequence can be created by almost any generator, in such a way it resembles random numbers as closely as possible. The only problem is that they are periodic, so they repeat themselves after some time. It is, however, sufficient for the needs of computer games and slot machines.

RNG in the world of slots

RNG is essential not only for math wizzes, but also for fans of slot machines and gambling entertainment overall. Modern versions of slot machines have built-in software that works on the RNG principle. This control center then has control over every game and individual spin, and without undue exaggeration is referred to as the heart of every slot machine.

Thanks to the use of RNG, today it no longer the case that a machine would give out money only when it is full and needs to empty out. And neither does anything depend on when the jackpot was last hit or how long it's been since the last win. Modern casinos really give everyone the same chance.

RNG and fairness

If the chosen casino employes RNG, you don't have to worry about its fairness or reliability. Currently, every slot machine must have this function, whether it be a physical slot machine or an online one. In addition, all these systems must go through a rather complex testing process by law, which is why casinos and gaming houses demonstrate their use of this technology with various licenses. If they don't have a certificate or won't show it to you upon request, it's best to avoid them.

Even when using RNG, however, casinos need to remain profitable. So related to this is the RTP (Return to Players) check, which is a theoretical value that players should approach according to mathematical probability.

And last but not least, it is also a matter of choosing slots with the corresponding volatility. This term is borrowed from the real world of finance, notably investing. In the gambling world, it basically denotes the same. The higher it is, the more you can win, but you will have to wait a bit longer than with machines with lower volatility. In their case, luck will smile on you more often, but you with smaller winnings.

Role of RNG in bonus games

You get not only wins in the base game, but also bonuses on regular slot machines based on RNG. This means that they are determined only after your spin and, just like in mathematics, the situation balances out gradually. It is therefore likely that after the free spins and other benefits there will be a less successful period and so this pattern continues back and forth.

Hopefully, we have shed some light on the issue of the random number generator. After all, it is an important element that all slot machines in licensed casinos and gaming rooms have today. And it certainly doesn't seem as though it will get replaced by another technology anytime soon. Rather, we can count on its gradual improvement.

Gambling games are not just made for all lovers of entertainment, but especially for professional players. If you want to one of them, you will need to learn the basic terminology used in this world in order to maximize your chances of winning. One of the most important of these terms is the RTP, which you will encounter in most gambling games. What is it?

What is RTP and how does it work?

RTP, or Return to Player, indicates the return of slot machines and other games in online casinos, and is always stated as a percentage - you will most often come across an RTP between 92% to 99%.

For most players, it therefore represents one of the key indicators that helps them manage their game strategy better. The RTP calculation depends on the long-term average of game results, not the short-term results of individual games.

Therefore, if the machine offers an RTP of 95%, for every bet of 100 CZK the players will theoretically get a return of CZK 95 in the event of a win. But as already said, this is only an average calculation, so in the short term the actual return will be lower.

The meaning of RTP for online casino players

If you really delve into the world of online casino games, you will come across the term RTP quite often. It is important to note that RTP is not completely accurate and is only an average indicator that is calculated from the total volume of bets and not from individual games.

Even so, with its help, you can easily estimate the winnings you can collect in case of success. We will show you how this works on a simple example with a slot that offers an RTP of 96%.

In practice, this indicator tells you that, in the long run, the given slot should pay out 96% of the bet amount. However, this does not mean that if you bet CZK 1,000 and win, you will get CZK 960. In reality, the real amount will be lower, but it should always be higher than, for example, a slot with an RTP of 92% - so higher returns will only be noticeable after playing for a longer period of time.

So, for simplicity’s sake, RTP should only be approached as an indicator that will help you choose the slot or game with the highest return. However, the average value given cannot be expected to apply to any particular win.

RTP and volatility of slots

In addition to RTP, you will come across another concept during the selection of suitable gambling games, namely volatility. While RTP will give you an insight into the approximate return of the given slot, the volatility will inform on its level of risk. Volatility is therefore used to measure the average frequency and amount of wins. Although the two indicators are not dependent on each other, they are worth taking note of them while playing.

Overall, low volatility slots offer frequent wins and low payouts. High volatility slots are known for high wins, but they only come from time to time. While playing such a slot, you have a very small chance of winning. Normally you can choose between:

Fortunately, RTP and higher volatility are not mutually exclusive, so you can come across slots with low volatility and RTP around 92%, but also variants with high volatility and RTP above 98%. You can see specific examples in the table below.

Type of slot machine RTP Volatility
Starburst 96 Low
Gonzo's Quest 95 Medium
Book of Ra 93 High

When choosing slot games, first pay attention to the volatility, so that you know in advance what level of risk you are subjecting your placed a bet to. Then focus on the RTP, which should ideally be as high as possible.

RTP in online vs physical casinos

You should also take RTP into account when choosing between playing in online casinos and physical casinos. Online casinos usually offer a higher RTP, with their average value often ranging between 92% to 98%.

One of the reasons is the lower operating costs of running an online casino, as there are no expenses associated with renting premises or employee salaries. In addition, online casinos face much more competition, which forces them to offer higher RTPs to attract more players. On the contrary, classic physical casinos offer a lower RTP, which usually ranges between 75% and 90%.

A higher RTP will be more of an exception, as the casino must keep enough funds to run the establishment. So if you want to achieve higher winnings, an online casino will be a better choice for you. If, on the other hand, you want to experience an authentic gambling atmosphere, you will have to sacrifice part of your potential winnings.

What regulations is RTP subject to?

RTP is one of the regulated components of gambling. Specific parameters vary depending on the country in which the casino operates the slot machines. In the Czech Republic, the Ministry of Finance oversees regulation, subjecting all casinos to a thorough inspection.

One of the criteria is the fair setting of the conditions of the individual games, including the RTP, which must always be higher than 75%. In other countries, the minimum RTP ranges from 70% to 90%. Adherence to the rules is regularly checked, and testing is no exception. Dissatisfied players also have the option to file a complaint with the casino.

Myths about RTP

Like many other indicators, RTP is also victim to various myths that often lead to bad decisions by players. That's why it's important to really understand all the game terms. Let’s bust some of these myths now.

  1. Higher RTP guarantees a win

One of the most common and probably the most widespread myths is the notion that slots with a higher RTP automatically guarantee a win. However, this is nonsense. In fact, a high RTP only indicates that the slot in question offers a specific average return.

The only thing that the RTP can guarantee you in this case is a possible higher win, especially in the long term - for higher wins you must spend more time on the given machine.

  1. Slots with low RTP are pointless

Another myth is that slots with a low RTP are pointless and therefore not worth playing. The opposite is true, however. Slots with a lower RTP are not pointless, but they do offer lower winning amounts. If you also choose a machine with low volatility, you can count on the fact that wins will be more frequent.

  1. RTPs are customized by casinos

Many players believe that the RTP for slots is set by the online casinos themselves. Online casinos don't own slot machines, and it is therefore not possible for them to determine their RTP. It is the online slot developers who are in fact in charge of the various settings.

RTP is undoubtedly an important parameter that is important to take into account when choosing a suitable slot, but also other online gambling games. For beginners, it is enough to simply choose slots with a higher RTP. In addition, pay attention to the volatility, which should correspond to the level of risk you are willing to take during betting.

The world of online casinos excites at first glance, but at the same time overwhelms with a whole bunch of unknown terms. One of them is volatility, which is one of the basic building blocks of the game strategy of any seasoned player. Why is it important and how can you use it to your advantage? Read on to get a grasp on all you need to know.

What is volatility and variance?

If you want to take your gaming strategy to the next level, you will need to familiarize yourself with two basic concepts, namely volatility and variance. In fact, these are synonyms that you usually come across in the world of finance, but they quickly found their place in the world of gambling. Both terms express the risk associated with the variability of winnings, specifically as to how often and what amounts players can win on slots. Volatility is calculated based on long-term data, so it cannot be expected to accurately reflect the outcome of your game. In general, games with high volatility offer high winnings, but they don't happen often. On the other hand, low volatility games provide significantly smaller wins, but they come more often. In short, volatility is used to estimate the risk associated with a particular game.

Volatility and slot machines

Slot machines are an integral part of online casinos, which is evidenced by their great popularity among players. For them, volatility can generally be divided into three levels, which we will describe below.

Low Volatility – Low volatility slots are ideal for players who like stability. The frequency of wins is quite high, but their value is low. The game is thus less exciting, but on the other hand, you don't have to worry about high losses.

Medium Volatility – Medium volatility slots provide a balanced ratio of risk to potential reward. The amount of winnings is therefore fair and appears at a reasonable rate. In general, this is a suitable choice for players who are looking for a balanced and at the same time more exciting gaming experience and for those wanting to play for higher amounts.

High Volatility – High volatility slots are for those players looking for a rush of adrenaline. At the same time, they must reckon with a low frequency of wins, which, however, can climb to very high amounts Playing such slots is riskier, and often leads to higher losses.

Volatility Level of risk  Potential win Frequency of wins
Low Lower Lower Frequent
Medium Average Average Occasional
High Very high High Rare

Using the volatility rate, you can easily manage the level of risk during play. If you don't plan on betting big, don’t go straight for high volatility slots. It is better to choose less risky options with low volatility, with which you will not hit the jackpot, but you will minimize the risk of a big loss.

Volatility vs RTP - Why pay attention to them?

In addition to volatility, you will also come across the term RTP (Return to Player) in connection with slots. The latter monitors the return of the given slot machine, or the amount it will pay out to players from the money bet in the long run.

The RTP is always given as a percentage, and it usually ranges from 92% to 98%. Simply put, the higher the RTP, the higher the ratio of the wagered amount should be paid to you in the event of a win. Theoretically, a slot machine with an RTP of 95% will return to players CZK 95 for every one-hundred-crowns bet.

However, it should be noted that this is an average value calculated based on multiplayer games played over a longer period of time. Therefore, the actual amount of winnings may vary significantly during short-term play. Both volatility and RTP are important to consider when choosing a suitable slot.

Through volatility, you can easily control the risk you are exposed to, while with RTP, you can see how high your potential winnings can be. In terms of risk, it is recommended to choose slots with low to medium volatility and a high RTP, ideally above 97%.

Choosing the right slot based on volatility

Now that you know what volatility is and how it works, you can start choosing a slot machine that will suit your gaming strategy. Below, we will look at several points that are worth considering when choosing a slot machine.

Off-setting risk

Always pay attention to the level of risk you are taking when playing slots. If you are a conservative player, look for slots with low volatility. These comes with low winning amounts - this can be partly compensated by a high RTP.

Conversely, seasoned players with a high-risk tolerance will appreciate high-volatility slots that, with a bit of luck, can give them big wins. On the other hand, the probability of winning here is very low, which can lead to significantly higher losses.

Player's personal goals

In addition to risk, consider your personal goals, on which you will base your game strategy. First of all, make it clear to yourself if you want to play just for fun, or if it should be a long-term activity, the goal of which is profit. With the first variant, there is no need to overthink your budget or the RTP - on the contrary, focus on the volatility and the amount of the winnings you are aiming to get.

For longer-term strategies, it's good to also focus on RTP and a more sustainable way of playing. In the long run, it pays to stick to low to medium volatility, which you can intersperse with higher volatility slot play from time to time. Whatever strategy you choose, remember that only in a minimum of cases it is worthwhile to invest only in high-risk bets.

Bankroll management

When playing in online casinos, one of the most important aspects is the bankroll, or budget, that you intend to work with. Always set a limit in advance of how much money you are willing to bet and ultimately perhaps willing to lose.

At the same time, it is important to keep to this limit regardless of how the game unfolds. Otherwise, you can quickly get into trouble. For slots with low volatility, you can get by with a smaller budget, on the other hand, for slots with high volatility, it is better to enter the game with a higher initial investment.

TIP: If you want to check the effectiveness of the ATM, test it first with free spins.

The effect of volatility on casino bonuses

The volatility of slot machines plays a key role not only in the frequency and amount of winnings, but also in the availability of popular casino bonuses. In general, the more risk you expose yourself to, the bigger bonuses you will get - however, each casino sets its own rules.

High volatility slots usually offer more attractive casino bonus packages to motivate players to be more intrepid and take even more risks. High numbers of free spins are common, but the casino rarely offers them to you. You can reach bonuses much more often with less volatile slots, which, however, tend to have a lower number of free spins available, which also leads to smaller wins.

Myths associated with volatility

Volatility is a complex concept for most novice players that they do not know how to work with at first. In addition, several myths haze the real facts. Read on to bust these myths once and for all.

  1. Higher volatility guarantees winning

Higher volatility does not automatically mean a higher chance of winning. On the contrary, it indicates that if you win, you are more likely to secure a large amount. Unfortunately, with higher volatility, the frequency of wins is much lower.

  1. Slots with low volatility are not profitable

Low volatility slots won't offer you big winnings, but they're likely to yield higher returns in the long run. So, if you are among the long-term players who are patient and at the same time like stability, slots with lower volatility may be the right choice for you.

  1. Volatility decides your win or loss

Volatility, like RTP, is a long-term indicator and therefore has no direct effect on the outcome of individual games. Each spin on the slot machine is independent and completely random. Therefore, it is better to see it only as an indicator that will help you estimate the level of risk of a given bet, and not as an automatic confirmation of a win or a loss.

  1. High volatility slots are always a better choice

High volatility slots are no better or more profitable than low volatility slots. The choice of slot machine should always correspond to your individual preferences and game strategy. Moreover, remember that slots with high volatility offer high winnings, but at the same time come with a higher probability of loss.

Volatility is one of the decisive factors associated with the level of risk and profitability of bets on specific slot machines. However, your entire game strategy should not be based solely on volatility. It is best to take volatility into account as one of the important indicators that will help you evaluate the risk and potential of a given bet. In addition to it, also focus on the RTP and reviews of individual slots.

Both physical and online slots work on the principle of random number generation (RNG). Factors such as RTP and volatility also come into play and determine the level of risk of the game and the player's chance of winning. Basically, this is a game of mathematical probability, and it is therefore not possible to bypass their operation in any way.

However, you can take advantage of the benefits offered by casinos, in the form of various bonuses and rewards. If you don't want to invest your own money, bonuses that do not require a bet will be relevant to you.

Not all bonuses are made equal

No bet bonuses are an attractive way to start playing slots without having to deposit money into your gaming account. Casinos most often offer them to new players as part of a welcome package when registering in their online gaming room.

However, various promotions for existing players, or rewards for winning or loyalty, are no exception. Most often, bonuses take the form of:

Free spins – players can spin the machine's reels without having to bet money or credits from their bankroll (game account);

Bonus Cash (bonus credits) – a small amount in the form of game credits that can be used for betting in the casino;

Winnings from bonus bets are usually blocked in the account and cannot be withdrawn and can only be used for further betting. They are available for withdrawal only after you meet the so-called Wagering Requirements (requirements for spinning). In practice, this means that you will have to make bets in the amount of several times the bonus that you won before you can make a withdrawal.

You may also find that the casino will allow you to withdraw money, but only a part of it. It is also not unusual that the bonus credits are only valid for a few days, and if the player does not use them up, they will automatically expire. It may also happen that you will only be able to use the bonus on designated slot machines.

As you can probably see, all these measures serve to protect the casinos from the abuse of the offered bonuses, the so-called bonus hunting practice. Without them, it could easily happen that users would only withdraw the bonus and never even play the slot machines. After all, this is a business, not a charity.

Where to look for bonuses?

Luck must be met halfway and the same applies to bonuses. Of course, you can wait until the casino itself offers you the opportunity to get free spins or extra credits. But you will come across a wider range of interesting offers when you start looking for them on your own. But where to look for them? There are several options.

First of all, you can subscribe to the newsletter and start following the social network profiles of your favorite casinos, where they often highlight time-limited events, seasonal bonuses or various contests and free credits.

The group's Facebook pages can also be a rich source of inspiration, such as Free slot machines or Free spins and bonuses in casinos and bookmakers.

Various gambling websites can also be helpful. These include, for example:

Freespinhunters.cz – the best offers of bonus free spins from various casinos;

We also have an exclusive bonus for you, in the form of a competition that you won't find anywhere else! What is it about? All you have to do is register and play our slot for credits.

So, as you can see, the possibilities of winning in online casinos without having to place a bet are limited, but not non-existent. With a little research and creativity, you can have a lot of fun without risking your hard-earned money.

Slot machines are an integral part of every casino. Although the gameplay may seem simple at first glance, the reality is that playing slots can be quite complex. Various factors affect the game, one of them being the symbols that appear on the screen after each spin. Each symbol has its own meaning, which determines not only whether you land a win or some bonus function.

The evolution of symbols since the dawn of slot machines

Slot machines have been with us since the 19th century, but their appearance has changed significantly since then. Various basic symbols are used that can create winning combinations when three identical symbols line up in the right direction.

The first Liberty Bell machines featured card symbols that included hearts, spades, diamonds, and eventually bells. When a win was reeled in, the player received tokens that could be exchanged for various rewards.

In the 20th century, a big change took over - the classic card symbols were replaced by fruit. Specifically, it was an initiative of the American company Bell-Fruit Gum Company, which created gum machines of various fruit flavors, namely cherry, lemon, orange and plum. Depending on which fruit the player managed to land, he subsequently received a chewing gum of the same flavor.

Cherries, unlike other symbols, had a special meaning. The player only had to reel in one cherry symbol, and he was automatically awarded a win. The cherry symbol itself became so popular that it has remained associated with slot machines to this day. Over time, however, other special symbols began to be added, which bring extra benefits and bonuses to the game.

Modern digital versions of slot machines have symbols with different themes and meanings. Wonder what they are? We will look at all of them in detail below.

Basic symbol types

You can still find classic fruit icons in most slot machines today. Also very common is the number 7, which is generally considered a lucky number - that's why it found its way into the world of slot machines in the early stages of their development.

Instead of fruits, you can also come across symbols from card games such as hearts, spades, clubs and diamonds. A common symbol is also the BAR, which was originally the logo of the already mentioned Bell-Fruit Gum Company. Currently, BAR is associated with higher winnings, in value corresponding to the number of displayed symbols.

Special symbols in slot machines

In addition to the basic symbols, sooner or later you will also encounter special symbols. Basically, they are divided into wild and scatter symbols, which are then further divided into subtypes according to their function.

Wild symbol

The wild symbol in slots represents the same as the joker in cards. Its job is therefore to help players create winning combinations by replacing the necessary symbol - but it must not replace the scatter or bonus symbol. Its presence significantly increases your chance of winning. You can meet several species:

Available wild symbols and their functions may vary from slot to slot, but in most cases, they will at least partially resemble the symbols mentioned above. In addition, the ways in which wild symbols can be obtained can also be different - some require at least one win.

Scatter symbol

In order to win, it is not important that this symbol be lined up in a row, it can appear anywhere on the board. As with other symbols, you need to land three scatter symbols. You can win money, but also free spins, which tend to be more frequent. Starting a bonus game can also be a reward.

Bonus symbols and their functions

In addition to special symbols, you will also encounter bonus symbols during the game. These can be marked with the full name "Bonus" or just "B". The number of symbols needed to get a bonus is different for each slot machine. Your reward can be money, but also a bonus game, which most often includes:

Winning combinations on slot machines

To get a win on a slot machine, it is necessary to achieve a certain combination - usually to line up three of the same symbols in a row. However, if wild symbols appear on the scene, you secure a guaranteed win, even if you only have two or even one symbol. In some slot games, you can reach the jackpot with a certain number of wild symbols.

In addition, it is important to understand the difference between two important terms, paylines and win possibilities. They both indicate how you can win on the given machine.

Winning lines

Most slot machines have winning lines, also known as paylines. These are the lines passing through the reels, on which you must form a series of identical symbols to win. The number of winning lines can vary for individual machines, and players usually choose which ones to bet on. These do not have to run straight but can also zigzag or form a specific shape.

Chances of winning

More modern slots offer different winning options – also referred to as “ways” – instead of traditional lines. According to them, a winning combination can form anywhere on the reels if the symbols are placed on adjacent reels starting with the first one from the left.

This leads to hundreds of winning possibilities. Their number depends on the number of reels and set rows in the game. In general, you can come across the following slot machines:

How symbols affect RTP and volatility

The presence of special symbols can offer you several advantages, but also cause an increase in the slot’s volatility, or a decrease in the RTP. However, the difference is usually not that important.

In most cases, it is impossible to estimate exactly how many bonus symbols will appear during the game and how many of them you will use. Therefore, one only works with the average, which can vary between 90% and 95%. Considering that the minimum RTP is 75%, this is not a significant reduction to worry about.

When using wild symbols, especially expect a reduction in volatility, which will lead to a higher frequency of wins, but they will be lower. On the contrary, with scatter symbols there will usually be an increase in volatility, and thus a decrease in your chance of winning - the same applies to bonus games.

Playing slots is not as simple as it might seem at first glance. The plethora of combinations can really make one’s head spin. Now you know the basic characteristics of game symbol and what you can expect. Keep in mind that playing on slots requires practice and often a bit of luck.
