About the Game
Stack ‘Em is a 5×6 grid game with a maximum possible win of up to 10,000x.
The game involves stacking symbols on top of each other to increase multipliers shown below the reels.
In free spin mode, wins will increase the total multiplier with the size of the cluster.
The game starts with a fixed number of spins, indicated by heart symbols above the reels.
A question mark symbol gives a mystery reward that could be additional spins or a multiplier increase.
Connecting an X symbol with a win multiplies the win by the factor shown above the reels.
Multipliers and Base Game
In the base game, non-winning symbols are removed after each win.
Winning symbols are kept and dropped to the bottom of the grid. Each reel shows the number of winning stacked symbols.
Winning clusters are multiplied by the total multiplier values they are above.
For example, a cluster with multipliers 1x, 3x, and 2x will total 6x and multiply the winning cluster’s amount. This continues with more wins.
Freespins
Freespins are triggered by at least three scatter symbols in the base game, awarding five initial free spins.
Spins continue as long as there are hearts above the reels. In free spins mode, the total multiplier increases with the number of winning symbols.
Special X symbols multiply connected clusters, and a question mark symbol can grant additional spins or multipliers.
