Created by Play'n GO, the original Reactoonz cluster pays slot features a 7x7 grid where the symbols are a bunch of cute and colourful little aliens. Random Wilds and giant symbols add variety, while the Quantum Leap Generator is charged up following every win. Once it reaches 25 symbols, a special feature is activated. This can lead to Implosion, Demolition, Incision, or Alteration taking place with the potential to blast your bet to x4,570 its size!
The success of this sci-fi cluster pays slot led to the release of Reactoonz 2 with an updated look and set of new features, however it still blows you into cosmic space with its soundtrack and animation! This time, there’s a fluctuating alien present on every spin, giving you the chance to create Electric Wilds while charging up your metre. Fully charge your Quantametrer to set the mighty Gargatoon Wilds free. This one goes further into win galaxy potential, with the top prize at x5,083 your bet.
Space Miners from Relax Gaming brings us the interesting prospect of finding bug-eyed creatures who are mining for raw materials on a giant asteroid. The action is presented across a huge grid that starts with a 6x3 group of active symbols and 729 ways to win, with new positions being unlocked on every winning spin.
This space slot goes up to a million ways to win with Wild symbols expanding to cover all available positions. You’ll also want to look out for PowerUp symbols that are activated when you destroy blockers, which sets off the related feature. Three Bonus symbols are needed to trigger a free spins round. Start your countdown to playing as this galaxy grid can reward you with up to x50,000 your bet!
Space Spins slot by Wazdan sends us on another intergalactic mission with the six-reels filled with different coloured stars and celestial bodies. Rainbow Wilds are the highest-paying icons and also replace any other paying symbol to complete a winning line.
As is the case with most space slots we’ve been looking at, a free spins feature is brought into play when you land a certain symbol. In this game, you need three UFO Scatters to get ten free spins, while more Scatters mean more free spins up to a maximum of 25 for six UFO symbols. The free spins round also bring a boost in the form of the Space Pile symbols, which can land in rewarding stacks.
The idea behind Pigeons from Space by Playtech is that alien pigeons in cool little flying saucers zoom in over some of Earth’s most iconic landmarks. This sci-fi slot is played over a set of hexagon reels with the likes of the Statue of Liberty, the Eiffel Tower, and Big Ben, while the background is a star-filled sky.
The action gets more rewarding as pigeons swoop in over the playing area to drop special objects. Blue pigeons drop Wilds during free spins and re-spins, while purple pigeons drop crop circles that pay out a cash value. Free spins are awarded when two pigeons land on the reels during the base game.
Unlike the space themed online slots we’ve covered so far, Spaceman by Pragmatic Play is a simple crash game where your mission is to work out how far the Spaceman can fly. The starting point is when you’re asked to place your bet and when you do, you’ll be ready for space travel when the next round starts.
The Spaceman character initially stands under a UFO but when the betting round is over, he takes off and flies across the screen. As he blasts up and across the gaming grid, the win multiplier increases steadily, with a max x5,000 your bet possible!
The key to this game, but is knowing that a crash landing is possible at any time. So, it's a question of working out when to cash out before he crashes! There’s also a nice space twist of a full cash-out and a 50% cash-out option to muster through.
Rocket Reels by Hacksaw is a space adventure filled with rockets and differently-coloured space rocks. The game takes place over a 7x7 grid where you’re looking to land at least five matching rocks together. Rocket Reels can blast a bet to x10,000 its size with features that showcase a rocket smashing through rocks and leaving multipliers in its wake and a UFO that’s even more powerful, capable of removing a random number of symbols to be replaced by others.
Free spins are awarded by the Scatter symbol, which features an astronaut. You need to get three of these Scatters anywhere across the reels to win eight free spins. There’s also a Wild symbol that only appears during a free spins bonus feature that can create winning lines by substituting in for other icons.
Inferno Star was created by Play'n GO and carries on with the out-of-this-world theme we’ve seen in the other space slots so far. At first glance, it’s a traditional fruity slot with the likes of lemons, grapes, and watermelons making up the symbols across five reels with five paylines. However, fiery sun symbols add extra heat to gameplay.
The suns are this slot’s two most valuable symbols with the Raging Sun Scatter the highest-paying image in the game. You get a re-spin when this image lands on the middle reel. During a re-spin round, all existing suns on the screen are held in place while any new instances of the basic sun symbol become Scatters. A new re-spin is awarded until no more suns appear. Suit up, this space slot is a real scorcher!
Star Bounty comes to us from Pragmatic Play. The theme in this space slot game sees you join a team of space pirates in a sleek futuristic setting. The game is played on a 4x6 grid of symbols that feature crew members as the highest-paying images. There are 4,096 ways to win and the Wild symbol helps by completing winning combinations where possible.
Three or more of the free spins symbols trigger this useful feature, while a Missile Wild symbol appears on reels 2, 3, or 4. When it lands on the reels, you’ll see how it blasts into a randomly-chosen number of other symbols, turning them all Wild. This slot also uses the Tumble feature, which means that winning symbols are removed allowing new icons to fall into their place and hopefully create more wins for you. All in all, Star Bounty can pay you an out of this world x25,000 your stake win!
Another space slot from Pragmatic Play, Cosmic Cash has a light-hearted sci-fi theme where an alien and his UFO sit alongside the five reels. The alien is also the most valuable symbol, followed by a female astronaut, a couple of space creatures, and a set of interesting rockets. The Wild symbol has a flying saucer on it and can appear on any of the reels, replacing anything other than the Scatter.
A Scatter symbol has the game’s name on it and pays out a cash prize when at least three of them land anywhere across the reels. There are also money symbols with multiplier values and with six of them you will launch into a re-spins round.
At this point, the bonus round starts with only money symbols and blank spaces, but as the re-spins are played a UFO comes on screen to give you prizes that can end in the award of one of four cosmic jackpots.
Finally, Starz MEGAWAYS online slot from Pragmatic Play has a selection of intergalactic symbols including planets, stars, and gems. The precious stones are the most valuable symbols, with at least three needed for a payout.
With six reels and the Megaways system, this game features an ever-changing number of ways to win that can rise to a maximum of 117,649. A Wild symbol can pop up on reels 2, 3, 4, or 5 and replace anything but the bonus.
The bonus symbol is the other special image to look out for. This is the image that awards free spins when you get three or more of them at once. Six bonus symbols on a spin give a maximum return of 15 free spins. During these no-cost spins, a special set of reels is in place to make things even more interesting.
In addition, any Wild that lands during these bonus games also expands vertically to fill the full reel during free spins, together with other symbols of the same size. Megaways means mega wins of up to x10,000 your bet!
