How to Play

Please, check our simple guide to start playing Stack ‘Em online slot from Hacksaw Gaming:

  1. Find the game in the casino’s lobby and push the “Play” button
  2. Wait until the content is fully loaded
  3. Click to continue and proceed to the slot’s layout
  4. Use arrows to set the size of the bet. Min bet is €0.2, while the max bet is €100
  5. Check the info or change settings if you want to
  6. Start spinning the slot manually or with the auto-play feature

You can set requirements to spot auto-play, enable turbo-spin, and change visual and sound settings.

Stack ‘Em has a 5x6 grid and cluster pay mechanics. It means that symbols stay on the reel after a successful spin as long as they are part of the winning combination. Other (non-winning) symbols disappear while new elements replace them. A winning combination requires at least 5 connected elements.

During the regular game, the player will be constantly awarded multipliers. The overall multiplier of stake is the sum of multipliers of every row. These row-multipliers equal the number of winning symbols on a particular vertical row.

The slot has a bonus game, which can be activated with the buy feature for the price of 129x.

Stack ‘Em RTP and Volatility

Stack ‘Em is a high-variance spinner with an RTP of 96.2%.
The return to player of 96.2% is an average index for the industry. The good news is that the level of payouts doesn’t drop after buying the bonus. Stack ‘Em is a high-volatile game like most cluster-pay slots with an increased grid. Building a big and high cluster in the regular game is not easy. But that’s the only way to get good payouts and multipliers. Moreover, the chance of hitting the FS is relatively low, as you can see from the high-price of buy feature. We recommend playing this slot for more extended sessions to overcome possible swings.



Stack ‘Em

We can’t exactly say what the central theme of the slot is. It’s both funny and psychedelic with its symbols. The best part about the slot’s theme is the two main heroes: Canny the Can and Mona the Mouse. They stand on opposite sides of the gaming board, watching the process and even giving some reactions. Canny has already become a meme among gamblers because of his fun character.

The slot has a cartoon-like graphic and a lovely peaceful background of the young oak grove with birds signing here and there. You can hear a light soundtrack during the base game and a more fun soundtrack during FS. There are also a lot of sound effects of different actions (spins, special symbols, activation of features).

All in all, the slot looks and sounds brilliant. The duo of Canny the Can and Mona the Mouse is hilarious.

The choice of symbols in the slot may look random. But we think the provider tried to give the psychedelic vibes to the game. And did it successfully.

We have cheap symbols of letters (A, G, E, R, T) of the same value from 0.1x to 25x. More valuable symbols are scull, ship, leaf, and snake with the same payouts: 0.25x, 1x, 2x, 3x, 5x, 20x, 50x, and 100x. The most valuable element is “Thumbs Up” with the price twice of its peers. The special symbols of the slot are wild and scatter (mouse). Wild substitutes for all regular elements, while 3 or more scatters activate the free spins round. During FS, you will see other two special symbols (X, ?). Each has its meaning.

About Hacksaw Gaming

Hacksaw Gaming is a new innovative provider with unique gaming content. The company was established in 2018, and its first release was the Stack’ Em online slot. What a debut!

Hacksaw’s slots stand out from others because of their brave gameplay and unique storytelling. Take, for example, the Hand of Anubis online slot with its dark theme and ominous Ancient Egypt decorations. The company has a lot of talented mathematicians and likes to experiment with its content. And you can see it from games like Cubes or Cubes 2.0. The latter has an 11x11 grid, probably the biggest in the whole industry.

And the most shocking part about Hacksaw is the size of its portfolio. They have already produced more than 100 titles, including scratch cards and instant games.

Bonus Rounds & Free Spins


Stack ‘Em is looking fun and is also very fun to play. Let’s check the main features of the slot.


During the base game, you can multiply your winnings. To be precise, you will be getting an additional multiplier after each successful spin.

You can see multipliers below each reel of the slot. The value of these indexes equals the number of stacked winning symbols on each reel. Moreover, all winnings are multiplied by the overall value of all indexes. So, if you have 1x, 3x, and 2x below reels, the total value will be 6x. A multiplier is active until the end of the winning spin.

Free Spins

Catching 3 or more scatters on a grid activates the bonus round. For starters, the slot awards you 5 free spins. During this round, all winning symbols are counted. You can see the count above the grid in a special table. This count is your potential multiplier. If the “X” symbol connects with the winning line, the multiplier becomes active.

You can also catch an “?” symbol during FS. The mysterious element can give you different awards:

  • Additional multiplier to overall count (+1, +2, +5, +10, +25, +50)
  • Additional free games (2–5)
  • Multiply the total odds by 2x, 3x, 4x, or 5x

Bonus Buy

You can buy the bonus at the price of 129x of your initial bet.
