Space Stacks (Push Gaming) – Review & Demo Play

Space Stacks: Slot Overview

Space Stacks from Push Gaming swaps lines for Reelbets, letting me stake on individual reels that either pay Instant Prizes or trigger a feature. There are 10 reels in view: six Instant Prize Blocks, three feature reels labelled Astro, Flip and Apex, plus a Max Block that pays 5,000x. It looks spacey and plays like a mash-up of a slot and a bet board, which suits players who like taking positions rather than just setting a single stake and spinning.

A round starts after I place chips on the reels I want to cover. Before symbols drop, an Enhancement can raise the first six Instant Prize values by adding +2 to +1,000, or by applying multipliers from x2 up to x100. Symbols fall while blockers clear until one or more reels reach 10 active symbols. If I backed any filled reel, I get the linked prize or feature. If not, I get nothing for that round.

Space Stacks Slot Information

Betting is flexible. I can spread chips from 0.01 credits per choice, up to 100 on the first six Instant Prize Blocks, 20 on Astro, Flip and Apex, and 10 on the Max Block. The six prize reels start at 2x, 2x, 3x, 5x, 10x and 50x. The other reels read Astro, Flip, Apex and MAX. There’s a Bet on All option, a one-step undo, and a clear-all. The paytable lists average returns per block, which helps me size stakes with more confidence.

Space Stacks: Slot Features

Instant Prize Blocks are straightforward. If my covered reel fills first, I’m paid its displayed value, which can be improved by the Enhancement adding +2 to +1,000 or multipliers from x2 to x100 before the drop sequence starts. The Max Block works the same way but pays a flat 5,000x if I manage to land it. In practice, the lower prize reels tend to resolve more often, while the high-value blocks and feature reels need more patience.

Astro sends me to a 32-segment wheel packed with additions (+2 to +1,000) and multipliers (x2 to x100), plus Collect segments. I spin and keep stacking prizes and multipliers until the wheel hits Collect. It’s a steady build with the chance to spike if multipliers arrive after some additions. The pacing feels like a tidy balance between small top-ups and the odd jump when a chunky multiplier drops on top of a grown pot.

Flip is a 6x6 pick. I get 3 picks to reveal 1x to 1,000x prizes or a Rocket. The first Rocket starts an x2 total-win multiplier, then further Rockets raise it to x5, x10 and x100. Rockets don’t use up picks, which adds a nice sweat when they chain. Apex mirrors the base flow with prize reels starting at 2, 3, 5, 7, 10 and 20, Enhancement boosts of x2 to x20, then a three-lives system. Each filled column multiplies the running total again, lives reset on hits, and the feature ends when lives expire or all columns fill. Winnings are multiplied by my bet on the feature block.

Space Stacks: Slot Verdict

Space Stacks clicked for me once I treated it like a numbers-led bet board. I’ll often weight 3x to 10x, nibble Red 50, and keep a satellite bet on a feature reel. The default RTP lists at 96.23% with medium volatility and a 5,000x max win. The info screen breaking down returns per column is handy for shaping a staking plan. If you prefer to pick your spots rather than spin and hope, this format feels fresh and rewarding when reads line up.
