How Stack 'Em plays
Clusters of five or more matching symbols pay. In the base game losing symbols are cleared after a win while winning symbols drop to the bottom and stay, and each reel's multiplier counts the stacked winning symbols in it; a cluster is multiplied by the sum of the multipliers beneath it. Three or more scatters start free spins with five lives, in which every win adds its cluster size to a total multiplier that applies when the X symbol connects to a win, and the ? symbol gives 2 to 5 extra lives or adds to or multiplies the total.
Theme: Cartoon (Canny the Can and Mona the Mouse).
Features in this game
- Cluster pays: A pay system where groups of matching symbols touching each other on the grid win, with no lines or reels-from-the-left rule.
- Multipliers: A value such as ×2 or ×10 applied to a win, a spin or a whole feature, multiplying the amount paid.
- Mystery symbols: Blank or question-mark symbols that all reveal the same randomly chosen symbol after the reels stop.
- Free spins: A bonus round of spins played at no extra cost, usually triggered by scatter symbols and often with extra features.
