Where Can I Play Space Stacks Slot?


Space Stacks is yet another innovative game by Push Gaming, it deviates so from what is expected as normal for modern online slot games that it initially surprises but is so much fun that it succeeds. The start of the show is the Reel bets feature that lets you bet singularly on any of the individual reels spread across its unusual 10×10 grid layout. While the minimum bet amount is 0.01, you can go as high as 100 per bet if you’ve got deep pockets.

With 6 regular prize blocks in the base game and 4 feature and bonus block reels in the bonus rounds make for an interesting game which opens-up the scope for innovative betting strategies. The payout goes as high as x5000 of your stake amount along with plenty of step rewards in between.

Push Gaming is on a mission to provide unparalleled entertainment and keep on striving for new avenues to make online slots entertainment even better. They have more than 40 games and each of those has its own premise for innovation and unusual feature sets. Some notable Push gaming slots besides Space Stacks include Deadly 5, Fire Hopper, Mad Cars, Big Bamboo, and Jammin’ Jars.


The game revolves around the sci-fi theme with a red on a dark blue gradient outer space backdrop with shooting stars and rocket symbols to fully set the scene. The online slot features six symbols in the base game with an average payout between x2 to x50. These symbols include blue, purple, green, pink, yellow, and red Prize Blocks.

The default bet multipliers of blue and purple are set at x2, while it’s x3 for green. Alternatively, the default win multiplier is x5 for pink, x10 for yellow, and x50 for red.

The next three reels are Astro, Flip, and Apex features where the prize multipliers can go as high as x300 per bonus round. The last reel houses the highest paying Max Block symbol that grants x5000 of your bet amount.


Space Stacks has a Return to Player (RTP) of 96.03%, the data was compiled from millions of spins by many players over a lengthy period of time. Although this could vary depending on the stake level you choose. This means that the game returns 96.03% of the money it received to its players.

The rest goes to covers the casino’s fees for providing the service and to purchase more new top-tier titles for your enjoyment from all the leading game providers. Generally, the higher the RTP, the higher your chances of winning.

Variance is different from RTP in the sense that it’s a measure of the game’s volatility. This video slot has medium volatility, which means that you’ll see winning symbols land with moderate frequency.

The total number of reels and rows is 10 vertical and 10 horizontal, with six of them reserved for Prize Blocks. Each individual block offers an average payout ranging from x2 to x150. The last reel which houses the Max Block offers the highest payout, which is worth x5000 your stake.

Gameplay and Features

Right from the start, you’re prompted to choose the individual reels that you’d like to bet on but you can also bet on all of them with a single click. Here, you can choose any one or more symbols from the 10 reels including the feature blocks. Conversely, you could click on the pointed star in the middle, and it’ll select all of the reels and start free spins. Below that, you’ll see the bet denominations starting from 0.1 and going all the way to 100.

When you click on the spin button, the game triggers free spins and random instant Prize Blocks start to pile on each other. The first tower to reach the top is the winning reel and if you placed a bet on it, then you win. However, the game has much more to offer than just random blocks falling on each other. Here’s a list of all Space Stacks features.


This is unarguably the most appealing feature of the game where you can bet on individual reels or all of them at once. You also have to option to bet a different amount on each reel.

Enhancement feature

In the base round, the first six instant prize reels get a minimum of 2 additional values ranging from +2 to +100 in any column. This additional value is the enhancement feature. That additional value will then be added to the default value of that reel. For example, the first reel has 2 written on it, then a +3 enhancement feature takes place. The total value will now read 5.

Astro feature

This is a bonus feature which is triggered when you fill the Astro column to the top. Here, an instant prize wheel with 32 entries spins and you get whatever value it stops on. It has multipliers, additional values, and collects randomly sequenced on the wheel. You’ll be able to collect your spin winnings as soon as you land the collect option.

Flip feature

This is triggered when you fill the flip reel, and then you’re presented with a 6×6 board with an instant prize located on random positions and you have three tries. You win instant prizes in those three attempts.

Apex feature

It’s one of the bonus games where you see a similar 6 Prize Blocks interface, and random blocks will fall to pile up on each other. If no instant prize block falls in a turn, then you lose a life out of three lives. This keeps happening until you have no lives left and if some column reaches the top, then you collect its reward.

Max Prize Block

If you’ve placed a bet on the tenth Max Prize Block reel, you win x5000 of your stake when you fill the Max Block.
