The Double Stacks slot is a 5 by 3 classic slot game. It features Free Spins where the reels are packed to the brim with stacked Wilds. In Free Spins the Wilds can also double, potentially creating double the excitement! The Double Stacks feature is activated when a reel stops and all symbols on it are of the same type. When this feature is activated, all symbols on the reel will count as two symbols when calculating wins for the current spin.
When 3 or more Scatter symbols appear in the main game, Free Spins is activated. During Free Spins, stacked Wilds are added to the reels.
