RTP for your games is the theoretical statistical calculation of the return to the player according to each game's rules. Select a game and locate the Info/Paytable section to view the full game rules and the corresponding RTP.
As its calculation is theoretical and every outcome on slot machine games is random, the RTP expresses an average return based on gameplay over an extended period of time. So, it is more like a long-term indicator, rather than a sign of what could happen in the short term.
