Bonus timing and the random outcome
Four or more scatters start the Free Spins, but how often that happens cannot be known in advance. Each session is random, and one session can end well above or well below its starting balance whatever the RTP. The RTP figure describes a long run, not the next few minutes of play, so a short session tells you little about the game.
Two RTP versions exist for this game, and which one Crownplay Casino runs is shown only in the game rules. Look for the rules page inside the game before you place a bet, since that page is where the version is named.
The top prize is x50,000 the bet, a ceiling reached very rarely. It caps the payout rather than marking a target, so no session can be planned around it. Multiply x50,000 by your own bet to see what that ceiling means in money.
