A clear view of what remains uncertain
Before you choose a bet size, know that the bonus round cannot be timed. How often it comes is not known in advance. The result of one session is random, whatever the RTP shown in the game. The RTP describes a long-run average, not what happens in your next session.
Before you rely on any RTP figure, check which version you are playing. Uwin Casino runs one of the two versions listed here, and only the game rules show which one is live. Read those rules before you take any RTP as a picture of your own session.
When you weigh the top prize, treat the maximum win as a ceiling that is reached very rarely. It stands at x3,000 the bet, the most the game pays, and it says nothing about what you should expect. Nobody can say in advance when, or whether, a session comes close to it.
