Game Overview

Stack 'Em, created by Hacksaw Gaming and first launched in May 2021, is a high volatility online slot transporting players into a classic cartoon-inspired world. The game is set on a 5x6 grid and uses a cluster pays system, where you land a win by connecting five or more matching symbols either horizontally or vertically.

When you strike a win, the symbols involved drop to the bottom of the grid, while the rest disappear – letting new ones fall in and giving you more chances to win. This slot draws inspiration from 1930s animation, with characters like Canny the Can and Mona the Mouse bringing an old-school charm to your spins.

Its cheeky graphics are rounded off with a lively jazz soundtrack, adding to the sense of nostalgia. Stack 'Em isn’t short on features either: Multipliers Each reel comes with a multiplier at the bottom, increasing as you stack winning symbols on top.

These can combine to give your payouts a nice boost. Free Spins Nab three or more scatters to kick off the free spins bonus. You’ll get five spins to start, and as you win during the round, a global multiplier keeps climbing higher.

Mystery symbols can pop up too, awarding either more spins or beefed-up multipliers. Bonus Buy For those wanting to skip straight to the action, there’s a bonus buy feature that lets you purchase direct entry to the free spins round for a set price. With an RTP of 96.2% and a maximum win potential of up to 10,000x your stake, Stack 'Em delivers plenty of excitement.

It’s fully optimised for both desktop and mobile play, ensuring a smooth experience whether you’re at home or on the move.
