Stack’Em Slot Review

If you are a fan of vintage cartoons then chances are that you are going to absolutely love this slot by Hacksaw Gaming. The Cuphead-like game offers hours of entertainment and intuitive bonus features. Let’s check it out!

This slot isn’t for everyone as some people may find the visuals a bit old-school but we loved it. The story takes place on a grass field located at an opening between a series of huge trees. On the left side of the screen, you’ll notice a mouse and at the right, the main character with both of them dancing. The reel set appears tall and slim with the logo of the game standing on top.

The mechanics are slightly different than usual as the reels clear and new symbols appear falling from the top altogether. Winning combinations are formed by getting at least 5 vertically or horizontally adjacent symbols.

Hacksaw Gaming likes making such slots so much that almost all of their titles feature a funny and entertaining theme. They focus on quality over quantity which is why they haven’t released many games to date. If you are eager on having fun then feel free to also check out “Cubes 2” as well as “Om Nom”. Now, let’s take a look at how Stack’Em works.

How to Play Stack’Em

The game consists of 6 rows and 5 reels. Just like other games of the same developer, the controls interface can be found at the bottom of the screen allowing you to adjust the bet size, enable the autoplay function, buy a feature, spin, or enter the in-game menu to check out the paytable or customize the gameplay.

As for the stakes, you can bet anywhere between $0.20 and $100 per spin. Stack’Em is a high volatility game meaning scarce wins but with an increased chance of getting a big payout. The maximum exposure is 10,000x your stake while the RTP is above average at 96.20%.

Stack’Em features 5 low paying and 5 high paying symbols.  These come in the form of the letters A, G, E, R, and T followed by a leaf, a bird, a skull, a snake, and a thumbs up icon.

The slot’s special symbols are:

  • Wild – The wild substitutes for all other symbols except for the scatter in order to form or improve upon winning combinations.
  • Scatter – Get at least 3 of these symbols to trigger the free spins feature.
  • X/? – Special symbols that only appear during the free spins feature.

Game Rules

Stack’Em Features

There is no denying that Stack’Em is a fairly unique and fun game but what about its special features? Let’s check them out!


After winning spins, the non-winning symbols will disappear causing the winning ones to fall to the bottom. Below each reel, a value will indicate the number of winning stacked symbols on that reel. All winning combinations will be multiplied by the total value of the reels they are on. 

This process continues as long as new winning combinations are formed. If for example, the reels display values 3x, 1x, and 5x then the winning combination’s payout will be multiplied by the sum of these three values which in that case would be equal to 9x.

Free Spins

Getting at least 3 scatter symbols will trigger the feature awarding 5 initial free spins displayed as hearts above the reels. The free spins will continue until no hearts are left. Every winning combination increases the total multiplier by the number of symbols it consists of. The feature can be bought at the cost of 129x your current stake.

All winning clusters that connect with the X mystery symbol will be multiplied with the factor shown above the reels. The question mark symbol will reveal award one of the following:

  • 2-5 additional lives;
  • Add 1, 2, 5, 10, 25, or 50 to the total multiplier;
  • Multiply the total multiplier by 2x, 3x, 4x, or 5x.
