Space Stacks Features

When the game opens up, players set their bets aka chips on the blocks that they want to select. There are 10 potential blocks to bet on with 3 of those being special features. The other blocks are just instant prize blocks giving players the chance to win up to 5,000x stake.

Push Gaming allows players to place multiple bets at once with the Reelbets feature. This means that you can technically bet on everything at once!

The three features

The first is Astro - which delivers a prize wheel with 32 segments with multipliers, instant prizes and collection. Naturally, this ends when the collect button is selected.

Players can also trigger Flip which consists of a 6x6 layout with selectable prize tiles. There are 3 picks in total and when an instant prize is selected, the picks return to 1.

When all 3 picks have been used, the feature ends. Players can win multipliers of up to x100 in this feature. It's worth mentioning that the number of picks will not decrease if a rocket is picked.

Finally, there is an Apex feature which features multiplier enhancements of up to x20. The game takes players to a screen where columns are filled up similar to the main game.

After 2 columns have been filled, 3 lives are activated. When one or more symbols land, the lives reset back to 3. If no symbols land, lives will be deducted. This ends when there are no more lives left.

Apex

When the Apex fills up first, it triggers a special feature. This takes players to a new set of columns where symbols fall and players are given three lives. The goal is to trigger multiplier enhancements of up to x20.

Space Stacks - Flip

Flip

If the Flip section fills up first, then this feature will be triggered. There is a 6x6 grid with selectable prizes and players get the chance to pick 3. However, all rocket picks do not count and do not decrease lives.

Astro

The final feature that can be activated is the Astro feature leading to a prize wheel with 32 segments. Throughout the feature, players can win multipliers and instant prizes. It all ends when the collection section is awarded.

Space Stacks Review

It's safe to say that Space Stacks is unlike any other slot that we've come across. The best way to describe this slot is as a mix between table games and online slots.

According to the developer Push Gaming, this game was created to give something refreshing to players and we definitely think they have nailed that with Space Stacks.

The game plays on a grid of 10x10 and wins are made when a specific column that a player has bet on reaches the top of the grid. There is the chance to trigger three different features as well leading to the biggest wins.

Design

Despite having a simplistic set-up, the visuals of this game are at a top-quality standard expected from Push Gaming. In the background, players will find space filled with shooting stars and orbiting planets. It's certainly designed to a high standard.

Even the little symbols on the reels have an intense level of detail that is appreciated. It's worth mentioning that each of the bonus features changes the background slightly to different locations and colours which is cool to see.

As for the audio, it's a lighthearted techno track that is reminiscent of Starburst. It definitely builds up the intensity throughout with faster beats but it never feels too overwhelming.

Gameplay

Whilst Space Stacks can seem quite overwhelming at first, the gameplay is incredibly simple. When the game loads up, all you need to do is bet on the chip that you want and you can even bet on them all.

During the game, there are three features that can trigger leading to even bigger wins! It all comes together to deliver a solid online slot that contains table game elements.

At the bottom of the screen, there is the spin button as well as the different bets. It's worth mentioning that there is a little button next to the spin button that resets the bet entirely.

Win Potential

This is not your average slot, so the win potential is examined a little differently. With a strong RTP of 96.23% and a medium volatility level, you can expect a mixture of big and small wins.

The biggest win in this slot is 5,000x the stake which is achieved by filling up the MAX column. During our playthrough, we managed to win up to 1,000x stake which felt massive and we were certainly satisfied.

Our Verdict

Space Stacks could certainly be the next step in iGaming bringing table game players to the online slot world. Not only is the gameplay incredibly simple, but it's also full of fresh and exciting moments.

There is not a dull moment throughout this game and it's even better with the creative flare from Push Gaming. Forget crash games, it's all about Space Stacks!

Live Updates

Tune in to the latest news about Space Stacks as it happens.

Could Space Stacks convert table game players into playing online slots?

It's no secret that table game players and slot players are two very different gamers. Online slots are often seen as quite flashy filled with thrilling and innovative mechanics, whilst table games keep it simple but deliver solid entertainment.

The two worlds haven't ever merged...that was until Space Stacks. In a completely unique and original step, Push Gaming decided it was time to combine table game elements with online slots to deliver something never seen before.

What's so special about Space Stacks?

Unlike any other online slot, this game contains a betting feature that allows players to place chips on certain numbers and features. Usually in online slots, players just set the bet level and spin with that level. However, that is not the case in Space Stacks.

There are ten different options to choose from with three of these being features to trigger. The numbered bets can go up to 100, whilst the features can only go up to 20. Evidently, this all means that a player could bet on everything and guarantee a win.

The most interesting thing about this game is that there are three features throughout Apex, Flip and Astro leading to big wins. This shakes up the base game and constantly keeps you on your toes.

Table game mechanics in other online slots

Whilst it's evident that Space Stacks is definitely the first of its kind, there have been other online slots that have utilised table mechanics. All of the games with the Side Strike mechanic contain a special feature that allows players to place extra bets.

It all started with Rise of the Valkyrie Splitz that added in the Side Strike mechanic that offered players the chance to bet on green or red to gain extra wins throughout. It's worth mentioning that the Side Strike often increases the RTP as well!

Is Space Stacks the next evolution in iGaming?

There are many developers trying to shake up the definition of online slots and the future is certainly looking bright for enthusiasts. First came the crash game Spaceman, and now it is all about Space Stacks.

Honestly, this could be the game that brings in table game players and converts them fully to the dark side of online slots. Space Stacks is refreshing and unlike anything else we've ever seen...it's definitely something to behold when it releases on slot sites on the 26th of October 2022.
