Unseen bonus timing and random payouts
Decide your stake before the first spin, because the bonus round can arrive on any spin. How often that bonus comes is not known in advance. The result of one session is random, whatever the RTP version. Two sessions with the same stake can end in opposite results, and no one can say which you will get.
Read the game rules before your first session, because the RTP version your game runs is shown only there. Compare the figure with the versions table on this page, since each version pays back a different share of the stake.
Treat the maximum win as a ceiling that is reached very rarely, never as an expected result. Every round can end well below that top figure, and no session can be planned to reach it. The ceiling caps the payout. It does not forecast one.
