Out of this World – Our Pick of the Best Space-Themed Slots

For decades, space has fascinated us with cartoons like The Jetsons, films such as E.T. and Alien and TV shows including Star Trek and Blake’s 7.

As International Asteroid Day approaches on 30 June 2024, it seems fitting to delve into the cosmos with a mission to find some very out-of-this-world space-inspired online slot game.

Read on for our top online casino space-themed games of the year.

Starburst

We needed to begin with the classic Starburst. Every player’s favourite grid slot machine with wilds, re-spins, wild re-spins, gems and jewels. It can be found at the best online casinos. 

Players can fire their rocket ship into outer space and win multipliers of up to x500 their stake across 10 paylines in this galactic slot game by NetEnt.

Kraliens

CORE Gaming brings extraterrestrial civilisations to desktops and mobile devices in its slot Kraliens, with a fun space design and bright graphics.

Players will find a group of inhabitants from other planets as the main symbols in the 7×7 game grid. Wins are formed in a cluster. Every time players spin the reels, they will see the aliens gather into clusters and then explode, resulting in a payout. 

Each explosion will pave the way for new symbols to fall, increasing a player’s chances of bigger wins. Kraliens will award players with a potential max win of x2000 their bet.

Captain Xeno’s Earth Adventure

For space pirates, Captain Xeno’s Earth Adventure has a somewhat odd and humorous space-themed scenario.

Captain Xeno and his band of aliens stop on Earth to fix their battered pirate spaceship after their last intergalactic escapade.

Captain Xeno’s Earth Adventure is a volatile space pirate slot game from Play’n GO. It all takes place on 5×4 reels with 1,024 default ways to win. However, the random symbol split feature could deliver up to a maximum of 32,768 ways to win in the base game.

A surprising random wild modifier is also thrown into the mix, whilst the bonus game is all about upgrading the split mechanic to 3 and 4 symbols, awarding up to 100,000 ways to win and a potential of x10,000 the initial bet.

Pigeons from Space!

Pigeons from Space! whose theme of pigeons in flying saucers is hilarious and played on a rarely seen hexagonal grid of 36 paylines. 

There are nine symbols representing pay values, which are ranks of cards and icons of monuments such as the Sphinx and the Statue of Liberty, with the Sphinx being the highest-paying symbol.

Bonus symbols include Blue Pigeons and Purple Pigeons (double wilds), Wilds and Crop Circles (instant wins).

The features when pigeon symbols land include Respins with Wilds and instant wins from Crop Circles. When two pigeon symbols land, Free Spins are triggered with 6 free spins and sticky symbol mechanics. 

With excellent audiovisuals, the game has mid-high volatility, with an RTP of 95.97%. Players can bet anywhere between £0.10 and £500 per spin.

A good, entertaining slot with a possible win x55 of the starting bet.

International Asteroid Day

In addition to the selection of games featured above, there is a whole world of space-themed slot games available for players to enjoy on international asteroid day.

Baboon to the Moon, Space Miners Dream Drop and Space Donkey (yes, really!) are just a few slots that players can play to win real cash or can try for free in demo mode.
