Can anyone predict the next bonus round?
Choosing how long to play Santa's Slay means accepting that the bonus round may arrive early, late or not at all. Nobody can know its frequency in advance, and a single session is random whatever the RTP version. Two players with the same bet can see very different results on the same day. Set your budget before the first spin and keep to it.
Deciding whether the RTP version matters to you starts with the game rules, because only they state which version this lobby runs. Read them before you place a bet. Once you know the version, compare it with the table above only as a long-run average. Each session still follows its own path, whatever the number says.
Judging how large a win can become in Santa's Slay means reading the maximum win as a ceiling, never as a target. The top prize is reached very rarely, and no session can promise that you will be near it. A session can end far below that ceiling, and the stake is at risk on every spin.
