Stack 'Em review
A bright, deceptively cute slot about colourful little monsters that pile up into stacks. The core mechanic is right there in the name: matching symbols stack on top of one another, while special multiplier symbols multiply the whole tower at once. Stacks and multipliers show up more often in the bonus game, and that's where the potential of up to 10,000x is hiding. Easy-to-grasp mechanics, playful artwork and sharp swings in the wins made Stack 'Em one of the studio's early hits. A good way to get acquainted with Hacksaw's signature style without the darker aesthetic.
