Why one session cannot predict a win
96.71 percent RTP is a long-run figure, and it does not tell you when the bonus round will land. How often the free spins come is not known before you play. Two sessions at the same stake can end at opposite results, because each spin is random. The RTP does not change that for one session.
Ten fixed paylines pay the same way in every round, but the RTP version that Star Casino runs is shown only in the game rules. Open those rules before you stake, since the series includes releases with other RTP figures.
x5,000 is the largest multiple of the bet that the game pays, and it is a ceiling reached very rarely. Nobody can plan a session around it, and no spin is guaranteed to come anywhere close to it.
