How to play Space Stacks mobile slot

The Space Stacks slot introduced the brand new ReelBets mechanics by Push Gaming, where you choose which symbol and feature to bet and activate.

The Space Stacks Reelbets online slot is set on a 10×10 grid with 7 instant win symbols and three bonus game features. You place your bets, spin the reels, and once you’ve filled a reel with symbols, you win the prize on the reel – if you’ve bet on it.

Roulette fans should see similarities in the betting mechanics introduced in the ReelBets. So what are Reelbets? Before Space Stacks begins, you get to choose how much and on which of the 10 reels you want to place a bet.

You can bet 100 cash in one reel or spread as low as 0.01 on all 10 reels for a low 0.10 a spin. You only win the prizes on the reels if you’ve bet on them. It’s very different from other Push Gaming slots but with a very playable medium volatility, a high RTP of 96.23% and a decent top win of 5,000x your bet.

Fill the reels, and win instant cash or bonus game features

Once you’ve placed your bets on this Space Stacks slot, you spin the reels. Symbols drop on the reels. This continues until at least one of the reels (or more) is filled to the top with symbols.

On the left-hand side, you have the instant prize symbols worth 2x, 3x, 5x, 10x, or 50x your bet. Before the symbols drop, you can get extra random multipliers added to this instant cash win.

Then you can win one of three bonus features:

• Astro: Wheel of fortune with instant cash wins
• Flip: 6×6 pick me bonus with instant cash wins and multipliers
• Apex: Free spins where you get 3 lives to fill as many instant cash reels as you can

Finally, you have Reel 10 with the Max Block. Fill this reel, and you’ll instantly win 5,000x your bet – the top amount.

Is there an ideal Space Stacks Reelbets slot strategy?

The big wins will always be in one of the three bonus features and in the Max Block. If you want to win big in this Space Stacks video slot, you should place a bet on these.

However, as you would expect if you’ve ever played any kind of online slot machines, you mostly filled the instant cash wins of 2x to 3x your bet.

Personally, we are a little lazy. We placed the same bet on all the reels to match our overall bet amount and placed a spin. We hate the idea of filling a reel and not winning. It’s the best way to make this a mid-variance slot and keep your budget in check.

But if you love high variance slots, the Space Stacks Reelbets slot mechanics allows you to place 100 in cash on the Max Block and win 500,000 in cash.

It’s the equivalent of going all in on one number playing roulette VS our more cautious approach of spreading our bet over the table and placing a bet on black or red.

Bonus Features

How to Place Your Bet: You can bet anything from 0.01 to 100 in a single bet on any of the reels. Click on one or more blocks to add a stake to that block. If you don't place a bet and win on that reel, you won't win anything. You only win on the reels on which you've placed a bet. The maximum amount you can bet is 100 in a single bet.

You can change on each spin or turn on auto spin once you've placed your favourite bets.

A 'bet on all' button allows you to place the same bet on all 3 feature blocks and all 6 instant prize blocks.

How to Win: The reels fill up with symbols on a spin. As long as new symbols keep falling, you keep 'spinning.' Once a reel is full, you get the prize associated with that block, if you've bet on it - including any instant prize blocks or special features.

Instant Prize Blocks: The Instant Prize Blocks are valued at 2x, 3x, 5x, 10x, or 50x your bet. Place a bet on that reel to win. They are on the left of the reel set, and before you spin, it's possible to get 2x, 3x, 4x, 5x, 6x, 7x, 8x, 10x, 15x, and 20x multipliers.

The Max Block: Sitting on the right of the reel set, if you win on that block, you instantly get 5,000x your bet.

Astro Feature: If you've bet on this feature and won, you can spin an instant prize wheel with 32 segments. These include bet multipliers, instant prizes, and collect segments.

You continue to spin and win prizes until you hit a collect segment.

Flip Feature: You get a 6x6 layout where you pick 3 options. Underneath hides bet multipliers, which turn into cash prizes. Pick three, and you end the round.

However, you can pick rocket symbols that do not take away one of the 3 lives and increase the overall win multiplier of 2x, 5x, 10x, and 100x.

The prizes you can win are 1x to 1000x your bet.

Apex Feature: When this feature is triggered, you enter a new stacking feature with all 6 instant prize blocks of 2x, 3x, 5x, 7x, 10x, and 20x your bet with possible multipliers of 2x to 20x your bet.

After 2 columns have been filled, you activate 3 lives. If no symbol lands, you lose a life. If a symbol lands, you reset the lives to 3. When there are no lives remaining, the feature ends.

Space Stacks Review Conclusion

How much you enjoy this Space Stacks Reelbets mobile slot will depend on how much you like to place bets.

This slot lives and dies on the thrill of being able to place different bets on different reels and whether you enjoy playing roulette. It won't be for everyone.

But as a new concept and way to play video slots, this will appeal to players looking for something different.

An interesting option to try at your favourite casinos online, knowing you can always hop on to the more traditional and excellent Fire Hopper slot by Push Gaming if it turns out you don't want to overthink your gameplay.
