«Canny the Can is back in Stack ‘em! This time he brought his friend Mona the Mouse with him. Stack ‘em is a 5×6 grid slot 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. «
