RTP, or return to player, is the share of all money wagered on a slot that the game is set to pay back over a very large number of spins. A game with a 96% RTP is set to return $96 for every $100 wagered, across millions of spins.
What RTP doesn’t tell you
RTP is a long-run average across all players. It says nothing about a single session. You can win far more or lose far more than the RTP suggests in an evening, because each spin is random. How wins are spread out is described by volatility, not RTP.
Why one slot can have several RTPs
Many providers release the same game with several RTP settings, for example 96.29%, 94.21%, 92.30% and 86.24%. The casino chooses which version it runs, within what its state allows. That’s why the same slot can pay back differently at two casinos, and why a casino’s game page may show a different RTP from the provider’s.
How we show it
In the calendar we list every RTP the provider publishes, each linked to the page we found it on. When a casino publishes the RTP of the version it runs, we can add that too. If no RTP is published, we say “not published” rather than guess.
In the monthly numbers, each game counts once, at its highest published RTP. Games above 96.5% are flagged in green. That line is a marker, not a recommendation.
