Search a slot →What is your real RTP?
RTP (return to player) is the share of your bets a game pays back over the long run. The rest is the house edge: a 96% slot keeps 4%. Rakeback hands part of that edge back to you, so your real RTP is higher than the number printed on the game. With 50% rakeback, a 96% slot plays at 98%. These tools show you exactly how much, at each casino.

Are the results exact?
