Figures are the return-to-player values the games themselves report, averaged per casino. Sample sizes differ, so read the game count alongside the average.
Two cautions before you use this list. First, sample size varies: an operator with three hundred tracked games gives a more stable average than one with thirty. Second, the range matters as much as the mean. A casino averaging 96.3% with a floor of 94% is running some noticeably worse games than one averaging 96.3% with a floor of 95.5%.

Highest reported RTP in our sample. A high headline figure still says nothing about volatility.
A high RTP does not make a game safe or a session profitable. It narrows the gap between you and the house on average, which is a smaller effect than most players assume and a real one over volume.
Why the differences are so small
Slot studios build to a band that operators will accept, so the vast majority of the market clusters between 96% and 97%.
| RTP band | Games | Share of sample |
|---|---|---|
| below 94% | 50 | 1.9% |
| 94-95% | 17 | 0.6% |
| 95-96% | 47 | 1.8% |
| 96-97% | 2472 | 92.5% |
| 97% and above | 87 | 3.3% |
Across 2673 game entries tracked in our database.
The practical consequence: chasing a 0.3 percentage point difference in reported RTP is not a strategy. What actually changes your cost of play is whether the casino returns part of its edge to you on every bet, and whether you have to clear a playthrough to see any of it.
