Slots Payback Percentage

(editor) | Updated:

When you first take a look at the ever-popular slots genre, things might seem relatively simple. After all, you push a button and things happen on the screen. While this is true, there is a whole slew of processes behind the scenes that you never think about. One such factor to consider is the payback percentage of online slots. It is a vital metric for the entire industry and one by which we judge all casino games.

The payback percentage is often one of the first things you check when you start researching games in depth, and you should have a clear understanding of the role it plays in the gambling industry. To this end, we have written this review so that you can read up on this topic. In this article, you will find information about the basic functions of the payback percentage and the vital aspects that relate to it.

Payback Percentage Explained

Payback PercentagePayback percentage and return-to-player percentage are terms that are often thrown around in the online gambling industry, but what do they actually mean? The way casino slots work is that you bet money, and depending on your luck you may or may not receive a payout. For a casino to stay in business, it has to bring in money, and it does so by paying out less money than it takes in. The amount that it does pay out is referred to as the payback percentage or return-to-player percentage. It is the primary income source of online casinos, and it is what makes a gambling operation profitable.

The payback percentage is different for each individual casino game and slot title. This is due to the fact that every game comes with its own odds, payout ratios, hit frequencies, and so on. There are no two identical slots on the Internet, and each title offers a unique experience. Therefore, you can expect a different return percentage from each game.

The payback percentage indicates the share of the total turnover that the casino pays out over a long period of time. Those numbers do not indicate short-term payouts, and you should not confuse them with such. The data is gathered over the course of potentially millions of spins, far more than any single player can achieve in one gaming session.

The payback percentage is the primary metric that gamblers use to judge the fairness of casino games. Basically, the higher the percentage is, the fairer the game is to the player base. It means that the game will be closer to true odds, and you will not suffer as much from the casino advantage. Of course, remember what we said earlier. If a game has a 95% RTP, it does not mean that you will receive $95 for every $100 you wager. The RNG system makes it so that every spin is random, and the outcome is independent of the previous one.

Relation between Payback Percentage and House Advantage

mobile slotsThe payback percentage and the house advantage are intertwined with one another. While the payback percentage indicates how much a given casino game pays out as rewards, the house advantage shows what percentage of all money the casino keeps as profit. The correlation between the two comes from how we calculate them. When you combine the house advantage and the payback percentage, you will always get an exact 100%, or in other words, the total amount of the turnover. You can always calculate one metric if the other is available. Therefore, if a slot game has a house edge of 5%, then the payback percentage will be 95%, and vice versa.

Role of Volatility in Online Slots

slots rngWhen you talk about RTP and house advantage, you take into account the long-term consistency of a game. What you do not see is how the title functions in the short term. This is where volatility comes into effect. This aspect is not the most discussed or refined in the gambling industry, and we have relatively little information to go on. This is mostly because software providers do not focus on it, and all the data we have about the volatility of a given game comes primarily from user experience. While it is not as precise as RTP or house edge, it still gives us some insight into how a game is supposed to function and what experience you may expect to have.

Volatility is a factor in modern slots that deals with how often and how much a game will pay out. It shows us the likelihood of scoring a win in the short term, and with this information we can better adjust our play style to that specific game. Slots generally fall into one of two categories: high volatility and low volatility.

High-volatility slots tend to deliver infrequent payouts over the course of your gaming session. When playing such a game, you can expect to go many spins without a significant win. To offset this, these titles will give you better rewards when they do hit, because wins come so rarely. A high-volatility slot can be distinguished from its opposite by the payout ratios for winning combinations. Typically, a 5x combination will pay significantly more than a 4x one of the same symbol. More often than not, the larger combination will give you between 5 and 10 times more money, though this is only an example. It is important to take this information with a grain of salt, as it may not be applicable in some cases.

As for low-volatility slots, you will find that they are the opposite of the high-volatility type. These games offer frequent hits, though at the cost of smaller rewards. You can reasonably expect to score a winning combination every few spins or so, though the rewards will not be something you write home about. Since winning spins occur more often, the payouts will reflect your odds of winning. A 5x combination will not exceed a 4x one in terms of rewards by more than five times.

What should I expect when I play a slot with a low RTP?

Asked by: Christian | Asked on: 2023-06-12

The first thing you might notice when you play a slot with a lower RTP is that your bankroll will likely last for fewer spinning rounds. Even a 2% difference in RTP might not seem significant, but it can reduce your playing time by about 33%. Ultimately, a lower slot RTP means you will exhaust your bankroll faster, resulting in fewer spinning rounds. A high RTP cannot guarantee how much you will win, but it does give you better odds of larger returns in the long run. After all, playing more spinning rounds naturally increases your chances of landing a sizable payout.

How come the theoretical return on slots is way different than the actual payback rate?

In theory, if you play a slot with a 98% RTP, you can expect to receive about $0.98 back for every $1 you wager. The casino’s expected profit on that same bet is approximately $0.02. In reality, the return a player sees over a long session often differs, because multiple factors influence the actual payback of slots.

As mentioned in the review above, volatility is one such factor. High-volatility slots often feature lower RTPs, as the potential for larger payouts can skew the balance. Other factors that impact the real return include hit frequency, bonus feature frequency, special symbols, and progressive jackpots. Generally, the riskier the slot, the better the potential payouts over time. This increased risk usually lowers the RTP, so the actual return is often even lower than the theoretical figure.
