What on Earth Slot Review

The What on Earth slots game can be found at Microgaming casinos. Microgaming as a standard do not publish the slots house edge information of their games. However they lease their slots games out to casinos using other software, some of which do publish this information. So far we’ve only found one casino – Virgin – that has published this information for What on Earth and they list the house edge as 4.02%. When playing at any other venue, this information should be used as a guideline only as the game may be configurable.

All those kooky space aliens have come at once and are competing to see who can land the best abductee.

This game is a 5 reel game with 9 paylines and you can bet up to 5 coins on each payline.

The ‘What on Earth’ symbol is wild, but only substitutes for the top two symbols on the paytable.

There are three bonus features when playing What on Earth (kind of). Both bonus features are activated when you receive 3 matching space ship symbols anywhere on the reels. When this happens you will be taken to a new screen showing 5 aliens in their space ships. You click on one of the aliens and a beam will pull something up into the ship – different objects/people award different prizes. If you beam up a ‘Contest’ symbol all five aliens will start beaming up people and things. At the end of the contest you are awarded the prize from the alien you picked to begin with. If you beam up a ‘Globe’ you will be taken to a new screen showing 4 different locations. Pick one of the locations then you will be taken to a new screen showing the five aliens. Click on one of the aliens and it will beam up a prize.


While we’ve listed What on Earth as having 3 bonus features, really they are all exactly the same and on top of this there really is little in the way of player interactivity. The low house edge is somewhat of a saving grace, but this isn’t a fantastic game overall.
