Space Stacks Slot Review

Space Stacks Slot Review

Fire up your rocket and blast off to the void above in Push Gaming’s Space Stacks slot machine to explore the vast universe in all its glory. Besides a magnificent view of outer space and striking planets, you’ll be treated to well-paying boosters, which include Instant Prize Blocks, Astro, Flip, and Apex features.

Welcome to Outer Space

The Space Stacks slot machine is a splendid title equipped with excellent graphics and space animation sequences that are quite literally out of this world. A futuristic tune resonant with many daft punk songs chimes on in the background to cheer you on in your mission.

To begin your expedition, you must first choose your bet by selecting the size of your chips and then click on the reels you would like to wager on. The first six reels of the Space Stacks online slot contain Instant Prize Blocks in different colors, bearing win multiplier values of 2, 2, 3, 5, 10, and 50. Meanwhile, the remaining four reels have Feature Blocks characters; Astro, Flip, Apex, and finally, Max, which is the best-paying character awarding 5,000x your bet.

Intergalactic Wins for the Taking!

As you play Space Stacks slot online, you’ll notice that this is not your average slot. Rather than spinning reels, clicking the play button will initiate a random sequence of filling the play area below the blocks. Filling a block will award you the corresponding payout or unlock a special feature. With a betting budget of 0.1 to 100 coins per play, the gameplay RTP sits at 94.29% and is complemented by high variance. Here’s a paytable highlighting the average payout table you could expect from filling up the columns across all betting budgets:

Feature Block
Red (50)
Amber (10)
Magenta (5)
Green (3)
Purple (2)
Blue (2)

Reach for The Stars with a Feature Packed Program

Some of the intergalactic power-ups you’ll encounter in the boundless cosmos of the Space Stacks online slot include:

  • Astro 

A filled-up Astro blocks column unlocks a 32-segment bonus wheel with multipliers, instant prizes, and a collect segment. When you hit the collect segment, you receive all the payout accumulated in the Astro block feature.

  • Flip

You’ll trigger a 6x6 grid where you must pick 3 prize tiles that could award instant bet multiplier prizes or a rocket symbol. The rocket symbol awards an extra pick opportunity on top of earning you a win multiplier that increases from 2x to 5x, 10x, and 100x for each successive rocket selection.

  • Apex

An Enhancement Feature activates to set you on a path of landing random multipliers from 2x to 20x by filling up other columns. Moreover, filling two columns grants 3 lives where 1 life is taken away hit a blank play that doesn’t land a new symbol in one of the columns. The feature ends when you fill up all columns.
