Great Griffin Slot Review

The Great Griffin 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 Microgaming as a standard do not publish the slots house edge information of their games.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 two casinos – Redbet and Bet Victor – that have published this information for Great Griffin and they list the house edge as 3.21% and 3-4% respectively. When playing at any other venue, this information should be used as a guideline only as the game may be configurable.

The Great Griffin swoops down with riches galore gripped in its might talons.

This game is a 5 reel game with 50 paylines and you can bet 10 coins on each payline.

The 'Great Griffin' symbol is wild and doubles all wins it contributes to.

There are three bonus features when playing Great Griffin. The first bonus feature is activated randomly. When this happens the Great Griffin will swoop across the reels changing a random number of symbols into Great Griffin wild symbols.

The second bonus feature is activated when you receive the ‘Hooded Lady’ symbol on reels 2, 3 and 4. When this happens you will be asked to click on one of the Hooded Lady symbols and awarded a random prize.

The third bonus feature is activated when you receive 3 or more of the ‘Great Griffin Logo’ symbol anywhere on the reels. When this happens you will be taken to a new screen and given the choice between 15 complimentary spins with a 3 times multiplier, 10 complimentary spins with a 5 times multipliers and 5 free spin with a 10 times multiplier.


A fairly standard set of bonus features leaves Great Griffin failing to break away from the pack.
