Unpredictable timing and single-session swings
Choosing a bet means accepting that the Money Respin may not appear in your session at all. How often the bonus round comes is not known in advance, and the result of one session is random, whatever the RTP. Two players with the same bet can finish with very different balances. Set the budget before the first spin, not around the bonus.
Deciding which version to play starts with the rules, because the RTP Star Casino runs is shown only there. The figures table lists the version this page covers, and a single RTP figure describes long-run returns, not one session. Check the game rules before your first real-money stake.
Deciding how far to chase a big win starts with the ceiling, which is x5,000 of the bet. Captain Kraken Megaways can pay up to that multiple, but reaching it is a very rare event. Read the maximum as a limit on paper, not as a result a session is built to reach.
