Unpredictable outcomes of every session
Before you choose a bet, know that nobody can say in advance how often the free spins round will come. Every spin is random. The RTP describes the long-run return across many rounds, not the outcome of one session. Your session can finish above or below what you staked, whatever the RTP.
Before you bet, find out which RTP version this lobby runs. That detail is shown only in the game rules, so open them before your first spin. The RTP is the return to player, and the version tells you which figure applies to your session.
Before you chase the top prize, remember that the maximum win is a ceiling. A round reaches it very rarely, so it should not shape how you size your bet. Set your stake from what you can afford to lose, and treat the top multiplier as the limit, not the expectation.
