Space Stacks

• A Slot Revolution at Roobet.

• If you think you’ve seen it all in online slots, Space Stacks is here to change your mind.

• This bold release from Push Gaming flips the script on traditional gameplay with its unique ReelBets™ system—a feature that gives you full control over where to place your bets.

• Whether you want to spread your wagers across multiple reels or go all in on one, the power’s in your hands.

• At Roobet, we love when a game breaks boundaries—and Space Stacks does exactly that, blending strategic decision-making with serious win potential.

How to Play Space Stacks

• Rather than spinning standard reels, Space Stacks plays out across 10 vertical blocks.

• At the start of each round, you choose which reels to bet on.

• Once the round begins, symbols drop in randomly, and the first reel (or reels) to fill completely becomes the winning reel(s).

• You only win if you placed a bet on the correct reel, making each decision feel meaningful and exciting.

• The six main reels award instant cash prizes, while three Bonus Blocks open up unique feature rounds.

• Reel 10? That’s the Max Block, and it’s got a monster 5,000x payout waiting.

Theme & Graphics

• Space Stacks takes you on a visually slick cosmic adventure, loaded with neon-glow aesthetics and a retro-futuristic interface.
• Everything from the sound design to the smooth reel animations works together to create a sharp, space-age vibe.
• The game board looks like a mix between a sci-fi dashboard and a classic arcade machine, and it’s incredibly satisfying to watch the reels light up when they’re filled.

Bonus Features

• There are three Bonus Blocks that can trigger special feature rounds when you’ve bet on them and they fill up:

1. Astro Bonus:

• A dynamic pick-and-click style game where you choose tiles to reveal prizes or multipliers. Risk meets reward in a space-age prize hunt.

2. Flip Bonus:

• Inspired by board games and coin flips, this bonus takes you through a series of coin tosses, each escalating the potential payout as long as luck is on your side.

3. Apax Bonus:

• A multistage feature resembling a galactic climbing challenge. Reach higher levels by unlocking spaces with increasing rewards, with each step feeling more intense than the last.

• Each bonus round has its own flair and win potential, adding massive replay value.

Bonus Buy Options

• While there’s no traditional bonus buy menu, you have the power to directly bet on the bonus reels—Astro, Flip, and Apax.
• This lets you focus your strategy and bankroll toward chasing those specific features, essentially creating your own version of bonus buying without needing a buy button.

Betting, RTP & Max Win

According to Roobet Space Stacks offers the following to players:

• Min/Max Bet: You can stake between $0.10 and $100 per round, with flexible betting across individual reels.

• RTP: The return to player sits at a respectable 96.23%, right in line with other high-quality slots.

• Volatility: This is a high volatility game, so wins might not come constantly—but when they hit, they can hit big.

• Max Win: Up to 5,000x your stake if you land the Max Block or crush it in one of the bonus features.
