Starlight Christmas outcomes cannot be forecast
Choosing a bet size for Starlight Christmas is a decision you make before the first spin, yet how often the bonus round comes is not known in advance. The result of one session is random, whatever the RTP. A quiet stretch tells you nothing about the next spin, and a fast start tells you nothing either, so treat each session as an independent outcome.
Deciding how much the RTP matters to you starts with the game rules. The RTP version running here is shown only in that screen, so check it before your first stake, not after. A player who skips that screen is working from an incomplete picture.
Reading the maximum win as a target would be a mistake, because the ceiling sits at x5,000 of the bet and is reached very rarely. Keep your stake in line with the money you can afford to lose, and treat the top figure as a limit on the game, not a forecast.
