From the ceiling on paper to your actual session
Before you pick a bet, whether A$1 or A$10, accept that how often the bonus round comes is not known in advance. Each spin is random, so the result of one session stays random whatever the RTP. Two players with identical bets can finish on opposite sides of the same evening.
Deciding how much weight to give the RTP starts with the game rules, because which RTP version is running is shown only there. Two RTP values exist for this slot, so the rules decide which one applies. Open the rules before your first bet and read the version there.
Planning around the top prize means accepting a ceiling of 5,000 times the bet, which is reached very rarely. The money figure scales with your bet, so the bet you choose decides what the ceiling means in A$.
