Clear expectations ahead of any stake
You decide to start a session, knowing that how often the bonus round comes is not known in advance. The result of one session is random, whatever the RTP. Two players with the same stake can finish with very different balances. So plan each session around money you can afford to lose.
You want to know which RTP version Crownplay runs before you play. That detail is shown only in the game rules, so look there before the first spin. The rules name the version in use, and each version has its own RTP.
You look at the maximum win before you bet, and it is a ceiling that is reached very rarely. Sweet Bonanza lists its top multiple of the bet, and the figure is the most the game can pay, not what a session is likely to return. Read it as the game's limit, not as a forecast.
