Set realistic expectations for every bet
Symbols land on the grid and the free spins may come on any spin, yet how often that happens is not known in advance. One session is random from its first spin to its last, whatever the RTP says. The RTP is an average taken over a very large number of spins, so it cannot predict what your own play will return.
Each spin on the 6x5 grid pays out under the RTP version the game runs, and that version is shown only in the game rules. Read that line before you start. The title alone does not tell you which version you are playing.
Tumbling wins, Multiplier Orbs and retriggered free spins can stack on the reels, but the top prize is a ceiling that very few spins reach. Treat it as the most the game can pay, not a target. A bigger bet raises the top win in money.
