Germinator Slot Review

The Germinator 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 Microgaming as a standard do not publish the slots house edge information of their games.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 Germinator and they list the house edge as 3.15%. When playing at any other venue, this information should be used as a guideline only as the game may be configurable.

What bugs are going to come into the Germinator’s crosshairs today?

This game does not use standard reels, instead you have a 6x6 board wherein any three matching germs in either a horizontal or vertical line will trigger a win. Once a win has been paid the germs involved explode allowing the germs above to drop down and new germs fall in from the top to fill the gaps. If new winning combinations are formed the process is repeated.

There is no wild symbol when playing Germinator.

There is one bonus feature available when playing Germinator and it is activated when three or more germs on the final layout have little pill symbols attached. When this happens you will be allowed to choose one strain of germs to remove from the board completely allowing germs above to fall down and new germs fall in from the top to fill the gaps.


Germinator is a very interesting slots game. The pill bonus feature undoubtedly allows you to affect the outcome of a round by choosing the germ strain to remove that will create the highest payoffs. However the stipulation that the house edge of this game does not change suggest that the game is artificially weighted so that player decisions have no effect on the end outcome. Either that or the 3.15% house edge is representative of either the best or worst possible playing strategy making the figure unreliable.
