Space Stacks

A trip to outer space is ahead but, however, this is not your ordinary venture into the cosmos to gaze among stars, meteors and black holes. No, casino software Push Gaming introduces players to the Space Stacks online slot.

What is so unique and special about the game, you might ask? The sole gameplay experience revolves around the Reelbets system, it all comes down to this clever mechanic when it comes to winning prizes as well as features.

Grab a cold one and let’s begin.

Theme and Symbols

As you figured out already, the theme of the Space Stacks online slot is a Space one with appropriate sound effects and a mesmerizing background. Needless to say, high quality combined with a player-friendly interface.

When it comes to the symbols of the game, these aren’t as important as in the rest of slot machines but they are present nonetheless. 

Betting Options and Features

The game is played on a 10x10 layout with Reelbets system, here’s how it works. The first 7 reels correspond to Instant Prizes with bet multipliers of 2, 2, 3, 5, 10 and 50 respectively, then we have Astro, Flip and Apex feature reels.

The last reel belongs to the Max, which awards the highest win of 5,000x the stake. Players pick the size of the bet by selecting chips and then clicking the reels you wish to bet on.

You can bet on as many reels as you like and should you wish to place your bets on all of the reels, then the Bet on All button comes handy. A pretty unusual approach so far for Push Gaming’s online slots, right?

Once settled in, the grid starts filling with symbols and blocker tiles that disappear with each spin. Once any of the reels gets filled to the top with 10 symbols the round ends. If you had your bet/bets placed on the successful reel/reels, the corresponding prize is awarded.

Now, there’s a chance for the Enhancement Feature to occur, adding values of +2 - +1,000 or multipliers of x2 - x100 to the first 6 reels ( instant prizes ). That’s about it when it comes to the instant prize reels.

The feature reels and their respective features are won in the same manner and here’s what each of those bring to the play: 

Astro - Players are presented with a Wheel consisting of 32 segments where Instant Prizes, Multipliers and Collect Segments are spread. The latter scoops up all of the rewards won by then and ends the game.

Flip - A 6x6 layout with Instant Prizes lies before players. You get 3 picks in total and, aside from the Instant Prizes, revealing the Rocket Symbol ( doesn’t count as a Pick ) unleashes the win multiplier which increases each time the Rocket is found.

Players lose 1 pick when an Instant Prize is found.

Apex - This one is rather similar to the base game with a couple of alterations. For starters, the Enhancement feature occurs with x2 - x20, then filling a column awards the prize. Upon filling the second column, the already collected prize multiplies it.

Once 2 columns are gathered, players are granted 3 lives where a life is deducted when no symbols land in view. The game ends once you run out of lives or if you manage to fill all of the columns. The final win is multiplied by the Feature Block which you can keep track of on the screen.

As far as the title’s best odds are concerned, the number is slightly above average at 96,23% while the volatility sits in the medium zone.

Wrapping Up

There’s plenty of unique and different things about the Space Stacks online slot, the majority of which revolve around the Reelbets system. However, there’s nothing complicated or hard to grasp, you’ll get it figured out in no time.

What is more, the game is completely optimized for all of your devices, including mobile gadgets.
