RTP explained
RTP stands for return to player. It is the share of all money staked on a game that the game is designed to pay back over a very long period, shown as a percentage.
It is a useful number for comparing games, but it is often misread as a promise about a single session. This guide shows what it measures, what it does not, and where to look for it.
What RTP measures
If a slot has an RTP of 96%, the game is built to return 96 units for every 100 units staked, averaged across a huge number of spins. The other 4 units are what the operator keeps.
The figure comes from the game's maths: the symbol values, how often they appear and what the features pay. It is calculated in theory and is also checked by simulation. It is not a record of what happened recently on a given site.
RTP applies to the whole game, including all bonus rounds. It does not tell you how often a feature appears or how big a typical win is. That is the job of volatility.
House edge is 100 minus RTP
The house edge is the other side of the same coin. Subtract the RTP from 100 and you get the long-run margin in favor of the casino. A 96% RTP slot has a house edge of 4%. A 94% RTP slot has a house edge of 6%.
Here is a simple example. Suppose you stake a total of 1,000 EUR across many spins on a 96% game. The expected return is 1,000 × 0.96 = 960 EUR, so the expected cost of play is 40 EUR. On a 94% game the same stake has an expected cost of 60 EUR.
| RTP | House edge | Expected cost per 1,000 EUR staked |
|---|---|---|
| 97% | 3% | 30 EUR |
| 96% | 4% | 40 EUR |
| 95% | 5% | 50 EUR |
| 94% | 6% | 60 EUR |
These are averages over a very large number of spins. A real session can finish well above or well below them.
Why your session will not match the RTP
A few hundred spins is a tiny sample. In a small sample, luck dominates, and results scatter widely around the average. Some players finish ahead and many finish behind, even when the game is working exactly as designed.
The more volatile a game is, the wider that scatter. A high-volatility slot can go a long time without a meaningful return and then pay a large sum, and both outcomes sit inside the same RTP figure.
That is also why a high RTP is not a way to win. It lowers the expected cost of play, but it does not make a loss less possible and it does not make a session any more predictable. A game is never "due" to pay back its RTP either. Each spin is independent, as explained in how online slots work.
Some games have several RTP settings
Certain providers release the same game in more than one RTP version. The maths is identical in every other way, but the paytable or reel weights are tuned so that the long-run return is higher or lower.
The casino chooses which version to offer, not you. Two sites can run the same title, with the same name and artwork, at different RTPs. The difference might be a point or two, or more in some cases.
Do not assume the RTP you read about for a game applies at the casino where you play. Check the figure inside the game at that casino before you stake money.
How to find the RTP in the game
Most modern slots show the RTP inside the game. The place varies by provider, but these steps usually work:
- Open the game and look for an "i", a menu icon or a "Help" button.
- Open the rules or paytable pages and scroll to the text about return to player.
- Note the exact percentage shown. If the page lists several figures, check whether they apply to the base game, to the bonus buy or to different settings.
- If you cannot find it, ask the casino's support team which version they run and ask for it in writing.

Using RTP sensibly
RTP is best used as one input when comparing similar games, together with volatility, the stake range and the features you enjoy. If two games are otherwise alike, the one with the higher RTP costs less in the long run.
It does not change the fact that gambling has a negative expected value for the player. Decide how much you can spend on entertainment, keep to it, and use the limit tools your casino offers. More support is on our responsible gambling page.
Frequently asked questions
What is a good RTP for a slot?
There is no fixed line, but many slots sit around 96%. A higher figure means a lower house edge, while a lower one means a higher long-run cost.
Does a higher RTP mean I am more likely to win?
Not in any way you can predict. RTP is a long-run average over a huge number of spins, and a single session can end well above or below it.
How is the house edge calculated from RTP?
Subtract the RTP from 100. For example, a game with a 95% RTP has a house edge of 5%.
Why does the same slot have different RTPs at different casinos?
Some providers offer several RTP settings for one game, and each casino chooses which one to run. Check the figure in the game's info screen.
