Stack’em is a 5×6 grid game featuring a max win of up to 10,000x.

Stack symbols on top of each other to increase the multipliers shown below the reels. Keep stacking them to multiply your wins!

In the free spin mode all wins will increase the total multiplier with the size of the cluster. You enter the game mode with a fixed number of spins, shown as heart symbols above the reels.
The ? symbol will give a mystery reward which can be either additional spins or increase the multiplier.
If the X symbol connects with a win on the grid, the win will be multiplied by the factor shown above the reels

Multipliers

In the base game, non-winning symbols are removed after every win, and all winning symbols are kept and are dropped to the bottom of the grid. Below each reel, a value is shown indicating the number of winning stacked symbols in that reel. All winning clusters will be multiplied with the total of the multiplier values they are above. For example, if a winning cluster is above 1x, 3x and 2x, those multipliers will first be added together to a total of 6x, which will then be multiplied with the winning cluster amount. This process continues as long as you stack more wins.

Freespins

Get at least three free spin scatter symbols in the base game to trigger the free spin feature. You are initially awarded 5 free spins, displayed as hearts above the reels. The free spins mode continues until no more hearts remain. In free spins, all symbols are removed between each spin. Every time you hit a win in the free spins mode, the total multiplier will be increased by the number of winnings symbols.
Example: If a winning cluster consists of 6 symbols, 6 will be added to the total.

On each free spin there is a chance that the special X symbol appears. All winning clusters that connect with this symbol will be multiplied with the factor shown above the reels.

The ? symbol will give you additional spins or increase your multiplier. The following outcomes are possible:

– 2-5 additional lives
– Add one of the following to the total multiplier: 1, 2, 5, 10, 25 or 50
– Multiply the total multiplier by 2, 3, 4 or 5
