The popularity of slots comes as no surprise to anyone, as they are extremely entertaining and can keep any player engaged. Whether you enjoy a certain book, movie, or pop star, you will likely come across at least one slot, if not several slots that you’ll enjoy. In addition to being fun, players also enjoy betting on slots because the games can sometimes be extremely generous to lucky casino enthusiasts.

Even though slots have always been and continue to be games of chance, many people are willing to risk some of their money for the chance to win hundreds – or even millions – of dollars. For this reason, many slot aficionados pay close attention to slot payouts and choose their games carefully.

If you are also interested in the payouts that slot games offer, you may want to continue reading this guide. We will help you understand slot payouts and teach you how to choose the slot variants that best suit you. One thing to keep in mind, however, is that no matter how high the RTP or variance of a slot is, it is still a game of luck. If luck isn’t on your side, don’t expect huge wins any time soon.


Understanding House Edge and Potential Return to Player

Whether we are talking about a land-based slot machine or you are spinning the reels of a virtual video slot, every casino game has both a house edge and a potential return. If you are curious about how a slot’s payout is determined, you should look at its hold percentage – commonly referred to as the house edge.

The hold percentage represents the portion of each wager that the house (casino) keeps. If you know the game’s Return to Player (RTP) percentage, you can easily calculate its house edge. Simply subtract the slot’s RTP from 100 to obtain the hold percentage for that particular variation.

If a slot has an RTP of 95%, it means that over a long period, for every $100 a player wagers, they will theoretically receive $95 back. Accordingly, the house edge is 5%, giving the casino a $5 profit from that same $100 in wagers.


RTP of Online Slots

The potential return of a slot indicates how much a player can expect to receive from their wagers over an extended period. Remember that RTP should not be taken too literally because it is calculated over a vast number of spins.

If you play a slot with a 96% RTP, it does not guarantee that for every $1 you bet you will get exactly $0.96 back. Instead, it suggests that after wagering $100 across many spins, you could theoretically end up with $96. Another key point is that a slot’s RTP often varies depending on whether you are making the maximum bet or choosing smaller stakes. In most cases, the highest advertised return assumes the player is wagering the max bet on every spin.

How to Calculate the RTP of a Slot

If you want to understand how much a particular slot may pay, the first statistic to check is the game’s RTP. In most cases, software providers and online casinos disclose the RTP of the slots they offer. Occasionally, however, this information is hard to find and you must rely on an alternative method.

Although RTP is calculated over a very large number of spins, you can still get a rough estimate for the slot you are currently playing. Remember that this figure applies only to your current session and does not represent the slot’s long-term RTP.

Calculating RTP for the Current Session

The simplest way to estimate the RTP for your session is to divide your total profit by the total amount staked during that session. For example, imagine a slot session in which you won $60 after wagering $50. Dividing 60 by 50 yields an RTP of 120% for that session. Conversely, if you finish with $30 in winnings after staking $50, the session RTP would be 60%.


Things to Consider When Calculating a Game’s RTP

The method described above can determine the RTP only for your current slot session. Calculating the overall RTP is far more difficult because many factors must be taken into account.

Estimating a slot’s long-term RTP requires you to consider:

  • The average number of wagers placed on the slot
  • The average payout amount the slot offers
  • The slot’s bonus features
  • The possible winning combinations

A slot’s RTP is typically calculated over hundreds of thousands, if not millions, of spins. In addition, the RTP is preprogrammed by the slot’s developers. Because it is impractical to invest that much time and money just to determine a slot’s RTP, we recommend relying on data published by software providers, online casinos, or independent slot-review websites.


Can You Trust RTP Percentages?

As noted earlier, a slot’s RTP is predetermined by the game’s software developer. Therefore, if the company lists a specific RTP on its official website, that figure represents the game’s actual RTP. Furthermore, when you play at a regulated online casino, you can typically find the RTP for every slot directly on the site.

Licensed Casinos Can be Trusted in Most Cases

Online casinos licensed by reputable regulatory bodies are required to disclose the house edge or RTP of the games they offer. In addition, they must maintain a minimum RTP across their portfolio and cannot adjust the house edge beyond the permitted limits.

Properly licensed casinos undergo regular audits by independent testing agencies to confirm that their games are fair. These audits verify both the published RTP and the actual RTP achieved in play. If an online casino does not provide a dedicated page listing each slot’s RTP, simply open the game and check its rules or paytable section; the percentage is usually displayed there.


One Game Can Have Several RTPs

In order to accommodate a wider range of casino operators, software providers often release the same slot with multiple RTP settings. These settings are usually lower than the highest RTP advertised by the developer and can mislead players who do not verify the percentage at the casino where they play.

While some regulators require their licensees to maintain a specific minimum RTP, others are less stringent. Therefore, it is essential to check the RTP of your favorite slots at the exact casino where you plan to wager real money. If the information is not available, consider choosing a different casino.

Virtual casinos licensed in the UK and Sweden must publish the RTP of each slot and use the highest RTP version offered by the developer. By contrast, casinos operating under licenses from Malta or other, less strict jurisdictions may offer the same games with lower RTPs.

If you know that a slot’s RTP is available at other casinos but cannot find it at the one you are visiting, you are better off playing elsewhere. After all, the most likely reason to hide a slot’s RTP is to offer the lowest possible version. This can significantly reduce your payouts and diminish your overall gaming experience.

For this reason, players should always verify the RTP of the slots they intend to play and ensure the casino provides the highest available return. Although the outcomes of games of chance are determined by the casino’s Random Number Generator (RNG), it is still important to make sure you are playing for the best possible long-term return.


How to Choose the Right Slot According to Its Volatility

When evaluating a slot’s payouts, you should also consider its volatility. While RTP indicates your potential long-term profit, volatility – or variance – describes how often small and large payouts occur. Depending on your preferences and bankroll, one type of variance may suit you better than another.

If you enjoy riskier play, slots with higher variance may be your best choice. High-variance games award smaller wins less frequently, but after a prolonged dry spell they can deliver substantial payouts. Conversely, low-volatility slots produce small wins more regularly, yet significant payouts are rare.

Is Volatility More Important Than RTP?

Although RTP ratings are important when selecting slots that might yield better returns, you should also pay close attention to volatility. In some cases, a game’s variance matters more to players than its RTP.

The theoretical RTP of a slot is usually achieved only after an enormous number of spins. For example, data from a UKGC-licensed casino shows that even after 50,000 spins, there can still be nearly a 5% deviation from the stated RTP. Reaching the true long-term return would require many more spins.

Therefore, sticking to the slot’s highest advertised RTP is primarily important to regulators, whereas an average player seldom plays enough spins to eliminate that deviation.

For this reason, a slot’s volatility may be more important to players seeking favorable outcomes. Choosing a low-variance slot improves the chances of reaching a smaller deviation more quickly because these games involve less risky bets, generate frequent small wins, and allow longer sessions.


Choosing Slots According to Their Volatility

If you have several days to devote to a low-risk slot, you can continue selecting games based solely on RTP. As noted earlier, it may take roughly 50,000 spins to approach a slot’s maximum RTP. If you are prepared to play that long, the fun factor may already be gone.

Although low-risk slots are not ideal if you are chasing larger payouts, you should also exercise caution with high-volatility games. Studies show that players who favor riskier betting styles tend to lose more than others. While high-volatility slots can be enticing because of their sizeable wins, extended losing streaks can quickly deplete your bankroll.

Nevertheless, if you are willing to tolerate the risk in pursuit of significant profits, high-volatility slots might be the way to go. Even the largest payouts on low-variance games seldom match the lucrative wins available in high-volatility slots.

Highly volatile slots generally have a lower hit frequency. Developers often pair a higher RTP with higher variance, making the games riskier but capable of delivering impressive payouts via bonus features and special symbols. A quick way to identify a high-variance slot is to check its paytable; if the lowest listed payout is still much higher than those on low-variance slots, you have likely found a high-volatility option.

While you play online, you will also encounter mid-volatility slots. These games sit between low- and high-variance categories, sometimes producing regular small wins and other times inflicting long losing streaks before a major payout appears.


Controlling the Slot’s Volatility

You may not realize it, but you can partly influence the volatility of the slot you are playing. A player’s actions almost always raise the variance; it is rarely possible to lower it.

Many video slots allow you to choose the type of bonus feature to activate. For example, you can select more free spins with lower multipliers or sacrifice some spins in exchange for higher multipliers.

A well-known example is Betsoft’s Good Girl Bad Girl. Choosing the Good Girl mode pays wins from left to right and results in low volatility. Selecting the Bad Girl mode pays from right to left and generates higher variance. There is also an option to be paid both ways, creating medium volatility.

Another method to influence volatility is by adjusting the number of paylines. You can increase variance by betting on fewer lines while raising your bet per line. Suppose you normally wager $0.01 on each of 30 paylines. By switching to a $0.02 wager on 15 paylines, you keep the same total stake but increase the slot’s variance.


Is a Higher RTP or Higher Variance More Important?

When selecting a video slot, its volatility can be far more important than its RTP. That does not mean you should ignore the return percentage, especially when comparing the same game across different casinos. Ideally, you should always play the version with the highest RTP offered by the developer.

To tailor your slot experience to your playing style, choose games with volatility that matches your bankroll and betting habits. If you dislike risk and are not chasing massive payouts, low-variance slots can provide plenty of entertainment.

Players chasing big wins, however, will likely enjoy high-variance slots more. These games are riskier but can deliver payouts that low-risk slots seldom match. Alternatively, mid-variance slots strike a balance by reducing risk while still offering the possibility of respectable wins over time.


Paytables of Online Slots

As already mentioned, the paytable of a slot can be extremely useful, especially if you want to estimate the RTP for a single session or determine whether a slot is low or high variance. Before wagering real money on a slot you have never tried, take a moment to review its paytable.

The paytable is an essential component of every slot. It typically contains the rules, paying symbols, special icons, bonus features, and paylines.

Although paytables vary in design because developers create diverse games with unique payouts and features, the information they present is usually straightforward. The first page or top section generally showcases the symbols used in the game and their payouts.

Paying Symbols

You will observe that some symbols award smaller payouts, while others carry higher values. The paytable also shows how many identical symbols must align to create a winning combination. Most slots pay for combinations of three or more identical symbols on a payline, although certain games grant a payout for just two of a kind. Payouts are typically displayed as the number of coins awarded for each winning combination, and some paytables clarify that these amounts represent a multiplier applied to the player’s bet per line.


Special Symbols and Bonus Features

The paytable also highlights any special symbols that may appear during play. Many video slots feature Wilds and Scatters with unique abilities that can trigger bonus rounds; if these symbols award payouts, their values are shown in the paytable as well.

Regarding bonus games, the paytable normally explains the features that can be triggered while the reels spin, helping players know what to watch for. If you do not see information about special features in the paytable, look for a separate “Rules” section.


Paylines and Ways to Win

When it comes to paylines, the paytable shows how winning combinations form across the reels. It typically notes whether the slot pays left to right, right to left, or in both directions. Certain slots offer multiple ways to win rather than traditional paylines. The paytable will state how many ways there are and how wins are created. Clearly, the paytable is an invaluable resource for learning all the essential details before you start spinning.
