Accept that no spin can be predicted
Before you pick a bet, note that nobody can tell how often the bonus round will come. The frequency is not known in advance, and the result of one session is random, whatever the RTP version in play. The RTP describes the average over a very large number of spins, not a promise for your session.
Open the game rules before your first spin. Only the rules show which RTP version of Razor Returns is running in the lobby, so check it before you compare the RTP versions listed on this page.
Treat the maximum win as a ceiling, not a target, before you set your bet. The top prize is reached very rarely, and reaching it is not something any player can plan for. The figure describes the limit of the game, not the likely result of a session.
