108 Heroes Slot Review

Released: July 2017

The 108 Heroes slots game can be found at Microgaming casinos. Microgaming as a standard now publish the slots house edge information of all their games at any online casino that holds a UKGC license (this is a requirement for all UKGC licensed casinos. As such we can say that the House Edge of 108 Heroes is 3.44%. When playing at any venue that does not hold a UKGC license and does not specifically publish the Return to Player information for their game, this information should be used as a guideline only as we cannot confirm whether or not this game is configurable.

When one hero just isn’t going to get the job done!

108 Heroes is a 5 reel game with 15 paylines and you can bet up to 5 coins on each payline.

The ‘108 Heroes Logo’ symbol is Wild.

There are two bonus features when playing 108 Heroes. The first bonus feature is activated when you receive 3 or more of the ‘Chest’ bonus symbol in a row on a payline starting from the left hand side of the reels. When this happens you will be shown 12 chests and asked to select the same number of chests and Chest bonus symbols that triggered the feature to win random prizes.

The second bonus feature is triggered when you receive 3 or more of the ‘Rock Outcrop’ scatter symbol anywhere on the reels. When this happens you will be awarded 10 free spins. During the free spins all wins are tripled. Free spins can be retriggered.


108 Heroes falls flat as Microgaming slots games go. The bonus features nothing particularly special or that even a moderately experienced slots player will not have seen before and the House Edge, while not off-putting, isn’t amongst the lowest being released today. It’s not a bad game but there’s nothing that really makes it stand out from the crowd.
