Before the first bet of a session
Deciding whether to start a session means accepting what nobody can see yet. How often the bonus round comes is not known in advance, and this page does not estimate it. The result of one session is random whatever the RTP is. The RTP describes an average over a very large number of spins, so a single session can end far above or far below that average.
Choosing how to play starts with knowing which RTP version you are on. That version is shown only in the game rules, not anywhere else in the lobby. Read the rules before the first bet, then match the version they name to its row in the table on this page.
Weighing the top prize means deciding what to expect from the game, not what the next spin will pay. The maximum win of Sweet Bonanza 1000 is a ceiling, and the game reaches it very rarely. Because the ceiling scales with the bet, the money figure in the table moves with the stake you choose.
