Space Stacks Game Review

Push Gaming is hardly afraid of pushing themselves to explore new and innovative ideas, and Space Stacks pretty much redefines what an online slot can be. The trademarked ReelBets™ system opens up a whole new dimension, as it allows players to freely choose which reels to place their bets on. You can bet on all reels if you wish, or apply any betting strategy you feel works best for you.

One or more reels will be filled with symbols each round, and the first reel(s) filled becomes the winning reel(s). You need to bet on the winning reel to win, and there are instant prize reels for up to 5,000x payouts. In addition, you get 3 bonus reels, and they trigger 3 unique and engaging bonus features that can also crack the 5,000x potential.

Space Stacks Slot Features

The game comes with 10 reels, and the first 6 reels are instant prize reels that award 2x, 2x, 3x, 5x, 10x and 50x your stake, respectively. Reel 10 is the Max Block, and it awards an instant prize of 5,000x your stake. In addition, there are 3 Bonus Blocks, namely the Astro, Flip and Apax blocks.

You can place bets on any or all reels, and the Enhancement Feature can upgrade the first 6 instant prizes by adding a value between +2 and +1,000.

If you placed a bet on the Astro, Flip and/or Apex bonus reels, and they get filled, the corresponding bonus feature triggers:

The Astro feature gives you a spin on an Instant Prize Wheel with 32 segments. The prize segments award between +2 and +1,000, as well as multipliers of x2 to x100. You will collect whatever prizes you land on until you hit the Collect segment.

The Flip is a pick game that plays out on a 6x6 board. You get 3 picks, and each pick reveals prizes between 1x and 1,000x your stake. You can also get a Rocket symbol that first triggers an x2 multiplier. After that, each rocket multiplier you get increases its value to x5, x10 and x100. Rockets do not reduce the number of remaining picks.

The Apex feature plays out like the base game, with some modifications. It comes with 6 instant prize reels, and they have starting values of 2, 3, 5, 7, 10 and 20. The Enhancement feature can boost the prizes by x2 to x20, and the prize of the first filled reel is collected. A second filled reel multiplies the original prize, and that happens from that point forward.

Having 2 filled reels activates a 3 life system, where each new symbol you land resets the life tally to 3 again.

Review Summary

We like that Push Gaming is pushing the boundaries of what a slot game can be, and Space Stacks is a highly innovative effort for sure. Whether or not it will be a success is an open question at this point, and it will take a while for players to get used to the gameplay. Most of the time the smaller instant prize reels get filled, and there are no features unless you actually bet on and fill a bonus reel.

This might be a problem for some players, as many regular slots come with base game features. Betting strategy is another element that becomes important in this game, and you get plenty of stats to help you out in the info section of the game.

Pros

• Place bets on which reels get filled
• Win instant prizes up to 5,000x
• 3 bonus reels w/ bonus features
• Max Block probability is 1 in 5,205

Cons

• Adjustable RTP ranges

If you love Space Stacks Slot you should also try:

Spaceman - is a burst mechanic release from Pragmatic Play, and it’s all about an astronaut traveling in space. It can be nerve-racking to see how long you dare wait until you collect your winnings, as the astronaut can crash at any moment. You get a 50% cashout option though, and the max win is 5,000x your stake.

Cygnus 2 - is a cosmic themed release from a more earthbound perspective, and this ELK release comes with avalanche wins that adds up to 4 extra rows. The gravity mechanic can tumble multiplier symbols to the left grid frame to activate them, and it never resets in the bonus round. The max win is 50,000x your stake.

Space Invaders - is a retro Inspired Gaming release with an 8-bit theme most players should be familiar with. It comes with tons of modifier action in the base game, as well as 6 different bonus games.
