Space Stacks is a game from Push Gaming that is similar to an online slot, though it has similarities. In our Space Stacks review, we will explain how the game works so you can decide whether it is suitable for you. It uses a 10x10 grid, is highly volatile and offers a maximum payout of 5,000x your bet. There are multiple special features that make its gameplay unpredictable.



Space Stacks uses a 10x10 grid but unlike most other online slots, it does not have paylines. During each round, each block (column) receives a random number of symbols. When you play Space Stacks, you bet on which block reaches 10 symbols first, though it is possible for two or more to do this on the same turn.
You can bet on any number and combination of blocks. There are six Instant Win Blocks with prizes ranging from 2x to 50x, along with a Max Instant Prize Block that pays 5,000x. The other three are Feature Blocks, each of which triggers a bonus feature.
Space Stacks has an RTP of 96.23%. This is an average as each of the 10 blocks has its own RTP. The slot game’s top payout is 5,000x, which you can win if you bet on the Max Instant Prize Block and it wins.
There are lots of different online casinos where you can play Space Stacks. Here is my pick of the best slot sites:



Space Stacks has 10 symbols, each of which can only appear on one block. Each is a different colour and includes some sort of graphic or image that ties in with the game’s space theme.

Push Gaming has designed the Space Stacks game to be mobile friendly. You can play it on both smartphones and tablets, and it runs perfectly well on both mobile sites and through casino apps. The visuals and soundtrack are the same however you access the game. When playing on handheld devices, the interface’s layout may be slightly different, but you should have no problems finding everything.



First, there’s the Enhancement feature. After placing your bet(s), any of the six Instant Win Blocks can have its value increase by anything from 2 to 1,000. The game’s three other features come into play whenever you bet on a winning Feature Block.

Space Stacks is a very interesting addition to Push Gaming’s collection of online casino games. Every turn, you bet on which of the blocks is the first to have 10 symbols. Six of them give payouts, one of them gives the top payout and the other three trigger special features. The game is themed well and offers an intriguing alternative to the tried-and-tested slot gameplay. It has an average RTP of 96.23%, a maximum payout of 5,000x and three special features that each work in a different way. If you fancy trying something different, Space Stacks fits the bill perfectly.
