How often does the bonus round land?
3 to 7 scatters start the free spins, but how often they land is not known in advance. Each spin is random, so the result of one session stays open whatever the RTP says. Two players with the same bet can end a session far above or far below where they started.
96.50 is the RTP of this version of Sugar Rush, and the series has other versions with their own figures. Which RTP version is running here is shown only in the game rules, so read them before your first bet. The RTP is a long-run figure and does not tell you what one session will return.
x5,000 is the most this slot can pay on one bet, and it is a ceiling reached very rarely. Hitting it cannot be planned, and the figure says nothing about how often smaller wins arrive. Treat it as a limit on the top prize, not as a target for any session.
