Long-run average, not your next session
Three scatters trigger 10 free spins in Sugar Rush, but no one can say in advance how often that happens. How often the bonus round comes is not known before you play. Each session is random, so one visit can bring no bonus round at all while another brings several. The RTP of 96.50 is a long-run average over many rounds. It does not predict your next session.
96.53 belongs to Sugar Rush 1000 and 96.58 to Sugar Rush Super Scatter, so the name alone does not tell you the RTP. Which RTP version runs in this lobby is shown only in the game rules.
x5,000 is the most Sugar Rush pays, a ceiling that players reach very rarely. At the example top bet of A$5 that is A$25,000, and at the highest bet allowed here, A$240, it is A$1,200,000. Nobody can predict whether a session will get near it.
