Space Stacks – Online Slot By Push Gaming

Space Stacks is a stacking slot from Push Gaming played on a 10×10 grid with a theoretical RTP of 94.23%. You bet on which stack of space symbols will reach the top first, and the special symbols trigger bonus features with a maximum win of 5,000x your bet. Read on for the specs, symbols and features.

Instead of paylines, Space Stacks asks you to pick the stack you think will hit the ceiling first. You do not need to move anything: one push of a button and the celestial bodies start stacking on their own. If you have never played a stacking slot, the sections below explain how it works.

Space Stacks Specs

RTP is a theoretical, long-run figure that says nothing certain about a single session. Read more in our guide to what RTP means. RTP can differ between versions of a game, so check the game’s info screen at your casino for the figure it uses.

Blast Off: Theme, Graphics and Sound

You drift in space among twinkling distant suns, with small background animations that make the vastness feel alive. Two planets sit close to the grid, one of them ringed. The upbeat music matches the theme, and the sound effects add futuristic beeps and boops to the space-faring fantasy.

Stacking slots are not something you see every day, so this one may make you do a double-take in the Push Gaming game range.

Heavenly Objects: Symbols

Ten symbols sit on top of the grid and fall into it each round: a Crescent Moon, a Triangle, a Cube, Earth, a Star, a Blue Meteorite, a Red Meteorite, a Rocket and the MAX icon. Random stacks of symbols fall onto the grid with each press of the button, and after a few drops the stack that reaches the top wins. If you bet on that stack you are paid, otherwise you lose the round.

Placing Your Bets

Bets are placed with chips, from 0.01 to 1. Before each round you can place chip bets on one or more symbols you think will fill first. After that, the enhancement feature triggers: the basic symbols fill up with additional symbols and multiplication symbols, which either add to or multiply the base value of the symbol.

Special Symbol Features: Astro, Flip, Apex and Max

The Blue Meteorite, Red Meteorite, Rocket and MAX icon are special. If you bet on one of them and it wins, it triggers a different effect:

• Astro: a Blue Meteorite win brings up a wheel of random prizes with 32 segments, split into bet multipliers, instant prizes and collectors. Spinning a collector awards the value of all the instant prizes.
• Flip: opens a 6×6 grid of selectable mystery tiles. You get three picks, and each time you reveal an instant prize your remaining picks drop by 1. If a rocket is revealed, the instant prize multiplier increases.
• Apex: the round plays as normal and the enhancement feature activates, but the possible multipliers are 2x to 20x. Once 2 reels are filled, 3 lives are activated. If no new symbol lands, a life is lost, and landing a new symbol resets the counter to 3.
• Max: awards the maximum payout of 5,000x the bet.

Our Verdict

Space Stacks is a different kind of slot, built around betting on stacks instead of lines, with four special symbols that trigger their own features. Medium volatility and a 5,000x top prize make it worth a try in demo mode if the format is new to you.
