Before the first spin of the session
3 scatters anywhere on the 7x7 grid start the free spins, and no one can say in advance when they will land. How often the bonus round comes is not known before the first spin. The result of one session is random, whatever the RTP of 96.47 is, because RTP is a long-run figure and says nothing about a single session.
96.47 is the only RTP version listed for Fruit Party. Which RTP version Katsubet runs is shown only in the game rules, so read them before the first spin. On the RTP table here, A$100 staked is the basis, which means the long-run return of 96.47 is A$96.47.
x5,000 the bet is the maximum win of Fruit Party, and it is a ceiling reached very rarely. Because the cap scales with the stake, a bigger bet raises the ceiling in money. In free spins, the round ends early and forfeits the remaining spins once the total win reaches the 5000x cap.
