Welcome to Stack ‘Em Slot

Canny the Can is back for more in Stack ‘Em slot by Hacksaw Gaming. Stick ‘Em was the first slot that featured this character, and now he is back for another fun ride with his friend Mona the Mouse.

It looks like a worthy successor to the original because of the clever use of Multipliers. It was launched in May 2021 and has become one of the most popular free slots created by Hacksaw Gaming.

It is not hard to see why this slot is so popular after the first few spins. We are excited to see how good it is as we move forward in this slot review.


How to Conquer Stack ‘Em Slot

This slot with 5 reels and 6 rows rewards you based on clusters of matching symbols. All you need to do is land 5 or more matching symbols that are connected to get a win in this slot. The symbols can be connected either horizontally or vertically. There can be many symbols in a cluster, and landing more than 25 symbols will give you the highest reward.

The special feature of this slot is that the winning symbols won’t disappear, and the rest of the symbols will disappear. The winning symbols will drop to the bottom and give you bigger potential wins through the Multipliers.

The thumbs-up symbol is the most profitable symbol that will pay you 200x of your bet for landing 25 or more symbols in a cluster. Even the lowest-paying symbols will pay you 25x of your bet for landing 25 or more symbols in a cluster.

The Wild symbol is a symbol with the word ‘Wild’ written on it. The free spins symbol or the Scatter is the symbol with the mouse and the short-form of Free Spins on it (FS).

You can bet in the range of €0.20 to €100, which is a pretty good range. Overall, the gameplay is simple to understand, and you won’t have any problems playing this slot.

Cartoonish Theme and Entertaining Graphics

Theme and Design

Compared to Stick ‘Em slot, this slot has made an incredible leap in terms of the theme and graphics. Hacksaw Gaming quickly realized that they had to improve their slots to compete with other developers. Honestly, Stack ‘Em looks exquisite and manages to do a lot with its simple design.

We can see Canny the Can with his rhythmic up and down movement on the right side of the reels. On the other side of the reels is Mona the Mouse, who is also doing the same movement as Canny. This slot will remind players of the old animation style, and there is no doubt that Canny the Can is a memorable character.

Symbols and Betting Range

The betting range is €0.20 to €100 per spin. This range is pretty standard for modern slots and enough to suit all types of players. As far as the symbols are concerned, their payouts are decent. A, G, E, R, and T are the low-paying symbols that will pay in the range of 0.10x to 25x of your bet.

The highest-paying symbols are a leaf, dead bird, skull, snake, and thumbs-up symbol. All high-paying symbols have the same payouts except for the thumbs-up symbol, as they pay in the range of 0.25x to 100x of your bet. The thumbs-up symbol will pay you 0.50x to 200x of your bet.

The payouts can seem a little low, but they are fair as one win can lead to another, and the Multipliers are also there to give you bigger wins. The potential of this slot is much higher than it looks.

Big wins are much easier to get during the Free Spins

Mighty Bonus Features

In this beautiful journey, you will be assisted by powerful Bonus Features. This slot has Free Spins, Multipliers, Wilds, and the Bonus Buy option. Let us explore the Bonus Features of this slot now.


The Wild symbol does what it is supposed to do, and that is substituting for other symbols. However, it doesn’t substitute for the Free Spins symbols.


After you get a win, the winning symbols will stay and drop to the bottom of the reels. The Multipliers below the reels will unlock and show the number of stacked symbols on the top of the reels. So if there are 4 stacked symbols on a reel, the Multiplier below it will be 4.

The Multipliers below all of the symbols involved in a win will be added together and multiplied with your win. You can continue landing symbols on top of each other and enjoying the Multipliers as the number of wins increases.

The maximum Multiplier you can enjoy is 30x because there are 5 reels with 6 rows. So when you fill all of the reels with winning symbols, you can enjoy a Multiplier of 30x.

Free Spins

Landing 3 Free Spin symbols or Scatters will trigger 5 Free Spins. The hearts above the reels represent the Free Spins. When you run out of hearts, the Free Spins feature will end.

The Free Spins have a Multiplier that will increase whenever you get a win. The Multiplier will increase by the total number of symbols involved in a win. So a win with 8 symbols will increase the Multiplier by 8.

The special X symbol is the key to using the Multiplier. The wins from all winning clusters connected with the X symbol will be multiplied with the Multiplier shown above the reels.

There is another special symbol, which is the "?" symbol. It will give you one of the following.

  • 2-5 additional Free Spins
  • Add values in the range of 1 to 50 to the total Multiplier
  • Multiply the Multiplier by 2, 3, 4, or 5

Bonus Buy

This slot gives you the option to directly buy Free Spins by paying 129x of your bet. Ideally, you should use this option if you can do it multiple times.

RTP, Variance, and Max Win

The RTP of the base slot and the bonus buy feature is 96.20%.

The variance of this slot is high, and it is completely justified.

The variance is justified because you can get a Max Win of 10,000x of your bet in this slot. You can go after the Max Win during the Free Spins as they have a Multiplier that never resets.

Is Stack ‘Em Online Slot Worth it?

Stack ‘Em serves as a great example of an innovative, fun, and rewarding slot. This deadly combination is rare in the world of slots, where most slots fail to excel in all areas. In short, there is no doubt that Stack ‘Em online slot is worth your time.

The graphics and theme are fun, and the symbols look great. The use of hearts to show the number of Free Spins will remind you of the older games.

The base slot is solid and can reward you with easy big wins. It is easy to win and continue getting bigger wins by stacking up the symbols. Remember that a single win with high-paying symbols can pay you a huge reward when it is multiplied by a big Multiplier.

Even if you fail to trigger Free Spins during the initial spin, they can be triggered by stacking up Free Spin symbols by landing wins. This makes it easy to trigger Free Spins. Obviously, the Free Spins are super powerful as the Multiplier increases really quickly during this feature.

Hacksaw Gaming has certainly caught our attention with this slot. You should try this slot and see how impressive it is.
