What is RTP and how does it work at online casinos?

What Does RTP Mean in Gambling?

RTP, short for Return to Player, is a gambling jargon. In the long run, it comes to the indicate the theoretical payout percentage. It is usually calculated as a ration between the probabilities and possible payouts in casino games. In other words, one can perceive RTP as the portion of money, bet on the casino, which goes back to the players.

To make it clearer, the average amount of winnings is labelled as RTP in Gambling.

Below is an illustration of how the concept works.

Let us imagine that the RTP at a certain slot is set at 96%. The probable outcome of users’ income in this case is this very 96%. If a player bets $100, his long-term payout ratio will be 96%, on the average. At the same time, it should be clearly borne in mind that this curve is not a short one, and the given percentage of RTP is covered over a longer period. Hence it takes time and quite a number of wagering on the part of users for this condition to be satisfied. Moreover, there is an individual aspect of RTP in gambling, wherein the variables change from player to player. So, while one player might get 0%, another could score big with 5000%. For clarity, it should be emphasized again that this concept is mostly theoretical and applicable as a long-run giveback.

RTP vs House Edge: What Is the Difference

Above was unfolded the gist of RTP and the tentative mechanics of its functioning. Now let us focus on what is left over once the players receive the expected return. As stipulated, in case a slot has 96% RTP, the remaining 4 percent goes to the casino and is labelled as House Edge in gambling industry. Hence, RTP and House Edge look like sides of the same coin, but they differ greatly in essence. While RTP is the winning probability of the users, the House Edge is the metrics which reflects the expected income of the casino.

However, the background of this concept extends far beyond mere calculations of percentage. It is of utmost importance to consider the notion of RNG (Random Number Generator). This is a special algorithm, which makes an indispensable part of every igaming software provider to back up the fairness of RTP in gambling. It determines that every spin is independent and legit. Audits like BMM, iTech Labs, eCogra and others usually test thoroughly the RNG mechanism for all the game provider companies.

RTP vs Volatility: Understanding the Difference

Another aspect where attention should be paid is the difference between Volatility and RTP. We mentioned above that RTP is calculated based on strict mathematical formula which is shown below:

RTP = (win1+win2+…win100)/(bet X 100) X 100%

To simplify RTP is the total sum of wins divided by the total sum of bets, multiplied by 100. Once again this is a hypothetical RTP which can fluctuate due to various circumstances and parameters, one of the most of which is volatility.

RTP vs Volatility

So, volatility is a variable is a measure for the risk of losing money based on the frequency and sums of wins and losses. Definitely it varies across providers, and slots from high to low. Specifically, low volatility slots are designed in a way to have more frequent payouts, but smaller in amount. Conversely, high volatility games give out much less frequently but in higher sums. The clear perception of volatility and its correlation to RTP can be used for more precise predictive analysis of game outcomes. Although the influence of the two on each other is explicit, yet it is quite significant.

Let illustrate this on an example of the slot with the same RTP but a different level of volatility.

Low volatility slot:

  • RTP: 98%
  • Payouts: smaller, but more frequently
  • About 60% of spins give back between $2 and $20 wins
  • The rest 40% does not bring wins in case a player bets $3 per spin for this case.

Results are as follows:

  • About 60% of the spins are to bring wins in between $2 and $20 dollars, while the rest 40% fail to bring any wins.

High volatility slot:

  • RTP: 98%
  • Payouts: Larger wins with less frequency
  • About 20% of spins result in wins between %50 and %100
  • The rest 80% bring no wins

Results are as follows:

  • Around 20% of the spins will result in large wins in between $50 and %100
  • However, most of the spins, namely 80% will bring no wins
