Plan your bet around the unknown
You choose the bet and how long to play, but nobody can know in advance how often the bonus round will come. Each spin is random, so the result of one session can land far above or far below the RTP, whatever the RTP is. Plan for a session that may end with no bonus at all.
Before you bet, check which RTP version this game runs in our lobby, because the game rules are the only place that shows it. Open the rules from the game window and read the version there before you commit any money.
Before you choose a bet, keep the top prize in view as a ceiling. The maximum win is reached very rarely, so it marks the limit of the game itself, not what a session will return.
