4 Scatters trigger 8 Free Spins. During Free Spins, 4 Scatters trigger 3 additional Free Spins. At the start of Free Spins, an Unlimited Win Multiplier is activated and starts at 1. The multiplier increases by 1 for every winning cascade in that round and is applied to the win achieved in that cascade.
Symbols fall into positions on the reels, instead of spinning. Wins are achieved by getting 5 or more symbols in a horizontal or vertical cluster. Winning symbols will be removed, remaining symbols will fall to the most possible bottom position on the reels. A new cascade will start to fill up empty reel positions which can create additional wins.
In the base game, a cluster of 5 to 10 Wilds is added to the gameboard. During Free Spins, a cluster of 5 to 8 Wilds is added to the gameboard. Spotlight Wilds can be triggered at the start of a spin or when all cascades are over.
One 3×3 Colossal Symbol and up to four 2×2 Colossal Symbols can land at any time. Only Majors and Minors can land as Colossal Symbols. Colossal Symbols can be of size 2×2 or 3×3. Colossal Symbols always land fully.
The Wild symbol substitutes for all other symbols except the Scatter symbol.
Wins are awarded for 5 or more matching symbols touching horizontally or vertically, or a combination of both.
