Can anyone predict the Top Charts Feature?
Deciding to spin Retro Tapes means accepting that nobody can tell in advance when the Top Charts Feature will trigger. How often it comes is not known before you play. The result of one session is random, whatever the RTP. Two players with the same bet can finish with very different balances, and no figure on this page predicts which of those outcomes you will get.
Deciding which RTP to play starts with the game rules. Which RTP version runs here is shown only in those rules, so read them before your first spin rather than guessing from the lobby thumbnail or a friend's report.
Setting your bet starts with the maximum win, which is a ceiling and not a target for any session. That ceiling is reached very rarely, so set each session budget around your bankroll, not around the top prize.
