Game Features

Sticky Win™ image
Sticky Win™

The Sticky Win™ feature triggers a Re-Spin when you land a cluster win with 6 symbols or when at least 3 Scatters land. During Re-Spins, winning clusters and Scatters stay in place. You keep getting Re-Spins as long as new symbols join the cluster or additional Scatters appear. The feature ends when no new symbols are added or no more Scatters appear.

Wild Features

The four corner positions can only hold Question symbols or Wilds. If a corner symbol joins a cluster win, Wilds trigger their special feature, while Question symbols turn into a Wild and activate its feature based on the table below. If four Wild features trigger at once, they activate in this order: Expander/Super Expander, Upgrader/Super Upgrader, Multiplier, and Cash Prize/Super Cash Prize.

Free Spins image
Free Spins

Landing 5 Scatters awards 3 Free Spins, starting with 3 multiplier symbols on the reels. During Free Spins, only multipliers can land, and each new multiplier resets the Free Spins counter to 3. Four special features—Unlock, Generate, Double, and Collect—appear in the corners and stay until Free Spins end. They activate when a multiplier lands next to them: - Unlock expands the play area by adding the top row first, then the bottom row (max twice). - Generate places 3 random multipliers and can activate up to 3 times before Collect triggers. -Double doubles adjacent multipliers and can also activate up to 3 times before Collect. - Collect sums all multipliers, removes them from the reels, and applies their value to the total win. If all four features trigger at once, they activate in this order: Generate, Unlock, Double, Collect.
