Stack ‘Em is one of the most innovative and aesthetically pleasing video slots to come out in the last couple of years. The game features a 5×6 grid and uses the cluster pays mechanism. It is a follow-up title to Hacksaw Gaming’s debut title dubbed Stick ‘Em, reintroducing Canny the Can, a familiar character from the original game.
Hacksaw Gaming launched Stack ‘Em in May 2021, and the game instantly became a hit, premiering on several major online casinos in the UK. It distinguishes itself by the rubber hose style of animation typical for cartoons of the 1920s and 30s.
Nevertheless, Stack ‘Em is a good game for reasons beyond its visual representation. It has an atypical reward system coupled with a few bonus elements, resulting in exciting and potentially rewarding gameplay. Here’s what you should know about this awesome video slot before trying it out.
Where Can You Play Stack ‘Em?
Stack ‘Em is currently one of the hottest cluster pays slots on the market. Hacksaw Gaming might not be the among most well-known video slot developers, but many UK casino sites have recognised the quality of their titles and are gladly filling up their libraries with them.
This means you’ll find Stack ‘Em on quite a few top-rated UK online casinos available for both free and real money play.

Stack ‘Em Gameplay
Stack ‘Em has a 5×6 grid, and a cluster pays system, lacking traditional paylines. At least five symbols must match in a cluster, connected either vertically or horizontally (if a symbol is one position away diagonally, it won’t count).
Once the win occurs, the winning symbols drop to the bottom of the grid and remain there for the next spin, while all remaining symbols disappear. Below each reel is a number indicating how many stacked symbols are currently on that reel, and those numbers translate into a cumulative multiplier. For instance, if the numbers below reels show 1x, 4x, and 2x, the multiplier for the current win will be 7x.
Apart from regular symbols that come as various letters and pictures with the thumbs up symbol paying the most, there’s a wild symbol and a free spins symbol. A wild can be part of multiple clusters at once.
Betting limits in Stack ‘Em range between £0.20 and £100. The game has high variance, so prepare yourself for a series of losing spins before finally hitting a big win. The maximum win in Stack ‘Em is 10,000x.
Stack ‘Em Free Spins and Bonus Features
The free spins round will begin once three FS symbols appear on the grid. The player initially receives five free spins shown as hearts above the reels. The number of symbols in a cluster of every win get added to the multiplier count. For instance, a seven-symbol win will add 7x.
However, not every win awards multipliers and instead activates when the special X symbol becomes part of the winning cluster. All clusters that connect with X are multiplied by the factor shown above the reels.
During free spins, you may also get a question mark (?) symbol that can either add two to five additional free spins, add one to 50 to the total multiplier, or add a value to the total multiplier of two to five times.
What Is the Return to Player in Stack ‘Em?
According to the game’s info page, the RTP of Stack ‘Em is 96.2%, slightly above the industry average. The developers came up with this result after simulating 10 billion rounds.
What Do We Think of This Slot?
If you’re looking for a quality cluster pays slot with a fun theme and unique elements, you’re likely going to have a good time playing Stack ‘Em. We truly enjoyed the game’s payout structure and overall design and consider it one of the most original and well-made slots that came out in the last few years.
What we feel can be an improvement is the free spins round. There are only five free spins at the start, and if you don’t get lucky with Xs and question marks, the round can finish quickly and leave you dry.
