Winning: €17
Multiplier: x17
It’s an interesting slot realization! I especially liked that the game has 243 paylines and a special round with free spins. I was given 3 free spins, and with each spin, the multiplier increases. When I have a winning combo, the spins are reset to the initial 3. Also, a stacked Wild is added before the last spin, which will definitely help out. As a result, I played for €1 and won only €17.40 (17.40x) in the bonus game. The mechanics are cool, but the paytable could be better.

Well, it's a good question... It's really convenient that your multiplier increases, but I also like a big pack of free spins at once :D
