Known paytable, unknown sessions
Choosing a bet does not set when the bonus round arrives. How often Free Spins come is not known in advance, and nobody can predict it from earlier spins. The result of one session is random, and the RTP only describes the long run.
Deciding how far to trust the RTP starts with the game rules. Which RTP version is running is shown only in those rules, so read them before you deposit. Any number in the tables on this page should match what the rules state.
Comparing the top prize with your bet is the first step. The maximum win is a ceiling in multiples of the bet, and the game reaches it very rarely. Treat it as the limit of the design, not as a target for any session.
