Can anyone predict the next bonus round?
You decide to spin Bigger Bass Splash, and the bonus round may or may not arrive in any given session. Nobody can know in advance how often the free spins will come. The result of one session stays random, and a 96.50 RTP describes the return over a very long run of bets rather than what happens to you tonight.
Before the first bet, you decide which version to play. Superb Casino runs the RTP version shown in the game rules, and the rules are the only place that version is stated. Other releases of the series list RTP figures of their own, so open the rules and check the version before you place a bet.
You decide how much to bet, and the top prize scales with that stake. Bigger Bass Splash caps a win at 5,000 times the bet, a ceiling that is reached very rarely. Reaching it is not something any player can plan for, so treat the figure as the outer edge of the game rather than a result.
