RTP, or Return to Player, is the percentage of total stakes that a game pays back to players in the long run. A 96% RTP means the casino mathematically keeps 4% of turnover — and that 4% does not go away even when your evening goes well.
What the number actually says
RTP is an average over millions of spins, not a promise about your session. The expected return on 100 USDT of turnover is 96 USDT; the actual result can be zero or several times that. How bumpy the road there is is shown by volatility: at the same RTP one slot pays often and little, another rarely and a lot. The fewer spins, the greater the spread — in both directions.
Why it matters at a crypto casino
RTP is the only way to put a price tag on a bonus. If you have to fill a wagering requirement with 3,000 USDT of turnover, at 96% RTP the statistical cost of that is about 120 USDT. Compare that with the size of the bonus before you accept the offer — the same calculation applies to every offer, regardless of how big the percentage on the banner is.
What to check
- The game's info window (the i button). That holds the number for that particular version, not the provider's marketing line. - The same slot, several RTP versions. Some casinos offer a lower-return variant — compare the info-window number with the range on the provider's page. - Table games. There the talk is of the house edge, not RTP: European roulette is at 2.7% because of the single zero, blackjack depends on the rules and the strategy. - When playing with a bonus, high-RTP games may fill the wagering at a reduced weighting or be excluded altogether.
A game's RTP is the only thing you know before a stake — the choice of casino determines which versions you are offered at all.
