From first spin to last, the outcome stays open
Before you pick a bet, know that the bonus round does not come on a schedule. How often it lands is not known in advance, and the result of any one session is random, whatever RTP version runs. With high volatility, a quiet stretch tells you nothing about the next spin. Size your stake for the session, not for one big hit.
Before you choose a version, look at the game rules, since they are the only place that shows which RTP is running. The versions sit within a narrow band, so the gap in return is small, and it helps to know which one applies to the session you are about to start.
Before you chase the top prize, treat the maximum win as a ceiling and nothing more. It is reached very rarely, and no session can be planned around it. The top prize is a multiple of the bet, so the money amount grows with the stake you pick.
