Before the first spin, not after the win
Each spin lands symbols on the 6x5 grid, and a session can pass with no Free Spins trigger at all. When 4 or more SCATTER symbols land anywhere, Free Spins start, but how often that happens cannot be known in advance. Nobody can predict the next result. The outcome of one session stays random, whatever the RTP version.
The reels run on one of three RTP versions, and only the game rules show which one Johnnykash Casino runs on this slot. Check the game rules before you play, because the difference between versions shows up over many spins, not in a short stretch of play.
Wins on the reels can climb toward the maximum win, but that ceiling is reached very rarely. The top figure is a ceiling on one bet's win, not a goal for a session. Set your budget and bet size before you start.
