Base Game
A cascading 5×3 grid on 20 lines. Winning symbols clear, one Wild is left in a gap they leave, and the multiplier doubles after every win, from x1 to x2, x4, x8 and on, until the cascades stop.

Feed the Tiki fireballs, feel his wild fury erupt and claim the volcano's molten treasures.
Deep in the jungle of a forgotten Polynesian island, the Tiki has slept for centuries in the shadow of a smouldering volcano. Angry Tiki DoubleMax is about to wake him.
Every win clears from the 5×3 grid, leaves a Wild behind and doubles the multiplier. Fireballs fill the Tiki masks above the reels, and three of them unleash Angry Tiki Wilds on that reel. In Volcanic Free Spins the multiplier carries from one spin to the next.
A cascading 5×3 grid on 20 lines. Winning symbols clear, one Wild is left in a gap they leave, and the multiplier doubles after every win, from x1 to x2, x4, x8 and on, until the cascades stop.
Any symbol that drops in can carry a fireball, and each one fills one of three slots in the Tiki mask above its reel. Fill all three and the Tiki erupts, adding 1 to 3 Wilds to that reel on each of the next three drops. Fireballs stay in the masks from one spin to the next.
Three Bonus symbols on the grid when the cascades end award 7 free spins. A Fireball Boost shares six fireballs across the Tiki masks to start, and the multiplier carries over from one free spin to the next instead of resetting.
