Our Top Rated Sci-Fi & Space Slots

The table below gives an overview of which sci-fi slots we’ve ranked as the best. We’ve included essential notes, such as RTP, paylines and features that make them stand out.

1. Zap Attack – Thunderkick

Features:

• Expanding Wilds
• Multiplier Wilds
• Free Spins
• Symbol Collection

Zap Attack captures a dystopian atmosphere set in the fictional town of Roswealth. Your goal is to fight off an alien invasion, and your reward for doing so is coins and lots of them.

The backdrop is a smoky, desolate landscape, which creates an eerie vibe with brilliant graphics synonymous with Thunderkick slots.

The high-quality visuals and soundtrack are just a couple of reasons this is one of the best sci-fi slots on the market. It’s one of the most immersive online slots we’ve tested, seamlessly adapted for online and mobile play.

2. Star Bounty – Pragmatic Play

Features:

• Free Spins
• Tumbling Reels
• Random Wilds

Star Bounty is one of the leading space slots by Pragmatic Play and takes you on an intergalactic adventure. It’s a futuristic theme set aboard a spaceship with a view of the alien world filled with tech and space bounty hunters.

We loved that Star Bounty offered something a little different, with a hexagonal grid layout, working brilliantly with tumbling reels and random wilds. Notable symbols include futuristic images, brave heroes, and masked villains, adding depth to the storyline.

3. Sparky & Shortz – Play’n GO

Features:

• Free Spins
• Stacked Symbols
• Boost Meter
• Wild Symbol

Take up the role of Sparky and Shortz, whose mission is to save endangered alien creatures in this epic sci-fi slot from Play’n Go. Your journey starts on the planet Alpha Labori, where it’s your job to guide the two characters to save the day for all alien life forms.

This is a brilliantly designed slot, set against a high-tech background with reels positioned within the chest of the robot Shortz. Everything from the colourful space rocks, alien symbols and floating aliens in test tubes makes this ga.me unique and captivating simultaneously.

With a high volatility rating, the immersive gameplay intensifies with the upbeat techno soundtrack, quickening as those big wins draw closer. A 10,000x max win, with multiple playing symbols, creates depth, giving Sparky and Shortz a deserved spot on our list of space slots.

4. Cosmic Fortune – NetEnt

Features:

• Avalanche Feature
• Free Falls Bonus Game
• Jackpot Bonus Game

Cosmic Fortune is NetEnt’s venture into space slots, and what an entry it is. The game takes you on an interstellar journey throughout the galaxy, where you must dodge meteors, UFOs and anything else that will derail your quest.

The slot benefits from a brilliant deep space background, with vibrant symbols that bring the game to life. An upbeat soundtrack is available throughout, creating drama for those big wins, with the game being individually developed for mobile and desktop play.

Cosmic Fortune doesn’t have the storytelling capabilities of Sparky and Shortz, but what it lacks in this area, it makes up for in gameplay. Most notable are the massive multiplier wins, bonus round jackpots and free fall bonus game.

5. Mystery Mission: To the Moon – Push Gaming

Features:

• Free Spins
• Mystery Stacks
• Wild Moon Symbols

Mystery Mission: To the Moon by Push Gaming is one of the best slots for sci-fi lovers. You aim to explore the cosmos, opening up new galaxies with hidden treasurers as a reward.

The design is futuristic, and the soundtrack adds much-needed drama to the game, even if it can sometimes be repetitive. However, the range of symbols, such as asteroids, ray guns, and astronauts, all add to one of the more creative games we’ve tested in the genre.

It’s another highly volatile game, meaning big wins are never too far away. With a max win of 10,000x, it’s a popular online slot for high rollers chasing the big payday.

Keep an eye out for the Mystery Stacks, which nudge reels and symbols to create multiple winning combinations and the free spins round, which is the best chance of landing that monster jackpot.

6. Starburst – NetEnt

Features:

• Win Both Ways (paylines work left to right and right to left)
• Expanding Wilds
• Re-Spins

Regardless of theme or genre, Starburst by NetEnt is one of the most popular online slots in the industry. It’s often linked with free spin promotions as part of casino welcome packages and is one of the best slots for beginners to learn how these games work.

Starburst is set in outer space within a cosmic backdrop. It features sparkling gems, lucky sevens and BAR symbols, which, granted, aren’t usually linked with space slots but play a vital role in the gameplay.

It’s a simple slot to play with low volatility, allowing you to win little and often. But don’t think for a second that those big wins aren’t out there, with a healthy 500x win multiplier constantly in play.

The main attraction comes in the form of the expanding wilds. These drop on the middle three reels, and when they land, they expand and cover the entire reel, triggering your re-spins.

7. Space Wars – NetEnt

Features:

• Cloning Pod Re-Spin
• Stacked Symbols
• Wild Substitutions

Weapons ready as you enter a thrilling intergalactic battle in NetEnt’s Space Wars. Your mission is to fight to save the galaxy against those pesky aliens, and by doing so, you’re rewarded with big wins and multipliers.

Space Wars is reminiscent of animated alien films and is a game that doesn’t take itself too seriously, with a quirky soundtrack as you pick fights throughout.

The gameplay is fast-paced but well-balanced, with a medium volatility rating. You have 40 paylines to work with throughout, including features such as Cloning Pod re-spins and stacked winning combinations.

8. Space Invaders – Playtech

Features:

• Win Both Ways
• Invaders Turn Wild
• UFO Wild Re-spins

If you’re a space and sci-fi geek, like we are, then you’re bound to have heard and probably played the iconic 1978 arcade game Space Invaders. Well, Playtech has brought the game to the online casino sector in what is a wonderful tribute.

The slot retains that classic theme from the game. Everything from the retro graphics to the bustling sound effects creates a huge nostalgia trip, all set in that familiar outer space backdrop where it’s your job to defend Earth from the pesky alien invasion.

Even if you’ve never heard of or played the game before, as a stand-alone slot, it’s highly impressive. The standout feature is the Invaders Turn Wild, where the cannon fires symbols across the reels to create winning combinations.

9. Attack on Retro – Microgaming

Features:

• HyperSpins
• Random Wilds
• Free Spins

Run it back to the vibrant neon-lit era of the 1980s with this brilliant little slot, Attack on Retro, from casino giants Microgaming. The game has been created alongside Triple Edge Studios and is set in a neon cityscape, which is a delight to play.

The soundtrack is one of the strongest you’ll find, with vibes of the film Drive for those familiar. You follow the main characters, Billy and Jesse, whose job is to fight off robotic invaders in what turns out to be a gripping storyline.

Attack on Retro has excellent gameplay, with HyperSpins, random wilds and free spins rounds, allowing you access to a 5,000x multiplier jackpot.

10. Arcane Reel Chaos – NetEnt

Features:

• Random Hero Bonuses
• Free Spins
• Multipliers

If you’re a fan of superheroes vs villains set in a dystopian future, then Arcane Reel Chaos by NetEnt will be right up your street. The slot is set in a dark, ominous cityscape, and it’s your job as the superhero to defend it at all costs.
