Knowing the limits before the first round
Symbols connect in clusters across the 7x7 grid, and three or more Scatter symbols can start the Free Spins on any spin. How often that happens is not known in advance, and no table can tell you when it will come. The result of one session is random too, whatever the RTP of 96.47 says about the long run.
Winning blocks tumble away and the grid refills from above, so one spin can pay out in several steps. Which RTP version is live is shown only in the game rules, so read them before the first spin rather than trusting a number on the lobby card.
Multiplier tiles land on winning blocks and multiply together, yet every block stops at its cap, and a Free Spins round ends early once its total win reaches the ceiling. The maximum win is therefore a multiple of the bet, reached very rarely, and it is not a figure to expect from any session.
