We’re heading off to outer space for this alien-themed online slot game from Microgaming, named What on Earth. This is popular 5 reel and 9 pay line slot which boasts colourful graphics and animations, heaps of characterful aliens and their spaceships, and some funky, eerie sound effects too. The game is fast-paced, good fun and offers a bonus feature which can be triggered by 3 different bonus scatter symbols.

There’s an unusual creature who appears to be within some kind of space-bubble or window so we’ll call him the space-alien as opposed to a spaceman, and he acts as the highest paying symbol. Joining him is the silver spaceship and a red asteroid. The lower value symbols combine traditional fruit machine symbols with the space-theme, so we have a melon planet, a plum planet, an orange sun and an apple meteorite! Clever designing indeed.

The wild symbol is the What On Earth logo, and this only substitutes for the 2 highest value symbols: the space-alien and the silver spaceship. There are 3 different types of scatter symbols – a blue shuttle, a red rocket and a green spaceship. If you land 3 blue shuttles on adjacent reels, 3 green spaceships on adjacent reels OR 3, 4 or 5 red rockets on adjacent reels – any of these will trigger the game’s main feature, the Beam ‘Em Up Bonus. During this game, you must select one of the alien characters to beam down to Earth; there will be a variety of characters available to abduct and each one carrying a prize – this is your chance to win a galactic prize!


Space is a popular theme amongst online slots, however What On Earth throws a different spin on the theme by throwing amusing, cartoon-style aliens and spaceships into the bag. I really enjoyed the theme, sound effects and straightforward gameplay. It’s always great to play a new bonus feature, and this is no different, although in my experience of testing out this game, the bonus took a long time to trigger. Perhaps this was just bad luck on my part, but nonetheless this is great cosmic game to play and well worth checking out.
