Set realistic expectations before placing a bet
On the reels, four or more SCATTER symbols anywhere on the grid start the Free Spins round. How often that round comes is not known in advance, and the result of one session is random whatever the RTP of the version in play. A session can end with no bonus at all, and the next one can bring several.
Each spin across the 6x5 grid is settled by the RTP version the game runs, and Winspirit Casino shows which version that is only in the game rules. Read those rules before the first bet, because the version sets the long-run return that the game is built on.
A winning cluster on the 6x5 grid can grow with tumbles and Multiplier hearts in Free Spins, but the maximum win is a ceiling reached very rarely. The ceiling is set as a multiple of the bet, so the cash figure moves with the stake. Reaching it is not something a player can plan or count on.
