Chasing a dry stretch of spins
Deciding to chase the bonus round means accepting that it will not arrive on a schedule. How often it comes is not known in advance, and no figure here predicts it. The result of one session is random whatever the RTP, so a higher RTP never promises a win. Set your budget before the first spin; the outcome stays open until the reels stop.
Checking the RTP means opening the game rules, because they are the only place that shows which version is running. Neither the lobby nor this page says which one is running. Read that section before you commit a session budget, because the version sets the RTP you are working with.
Choosing to aim for the top prize means facing the maximum win of Sweet Bonanza, a ceiling reached very rarely. The cap is 21,100 times the bet, so the number sounds large but describes the limit, not an expected result. Judge the game by how it plays for you, not by that figure.
