From the RTP figure to one real session
On the 6x5 grid, each spin decides whether golden pretzel Scatters land anywhere on the board, and four or more of them start Free Spins. How often that happens cannot be known in advance. The result of one session is random too, whatever the RTP version. A player can see the RTP as a long-run figure, but it does not predict a single evening at the reels.
Each spin on the reels runs on one of the three RTP versions of the game, and the rules screen is the only place that names the version in use. Read those rules before you decide how much to stake.
Winning symbols on the 6x5 grid vanish and refill, so a single spin can chain several wins. The top prize, x15,000 the bet, sits at the far end of that chain. It is a ceiling reached very rarely, not an expected result.
