Mighty Griffin Megaways Slot Review

Released February 2020

The Mighty Griffin Megaways slot is produced by Blueprint Gaming. Blueprint Gaming are one of the smaller slot development companies on the market at the moment and do not offer their own casino platform. Instead they lease their games out to casinos using other platforms. Blueprint Gaming do not always publish the RTP information for their slots in the paytable. However, in this instance they have done, which means we know that the house edge for Mighty Griffin Megaways is 4.05%.

Mighty Griffin Megaways is a 6-reel slot, with each reel varying in height. The number of symbols that make up a reel can change at random, with the potential for each reel to contain 7 symbols. There is an additional row of symbols at the top of reels 2-5. The game does not use traditional paylines, instead it operates with a maximum of 117,649 different possible “megaways”, which essentially means that you form wins when you land matching symbols across 3 adjacent reels, playing from left to right.

Avalanches – Every time you form a win the symbols involved will disappear, existing symbols will drop down into those places and new symbols will be added at the top of the reels. Win again and the process will repeat and will continue doing so as long as you keep landing wins.


This slot has a fantasy theme, with the particular focus obviously being Griffins. Essentially the Griffin concept could be replaced with just about anything given the design of the slot.

Special Symbols

Wild – The Wild symbol is the “Book”, which will substitute for all symbols other than Scatters.

Scatter – The Scatter symbol is the “Golden Griffin”. You need to land 3 or more of them anywhere on the reels at once to trigger the Free Spins feature.

Mystery – The Mystery symbol is the “Orb”. Mystery symbols will land on the reels and then spin around to reveal an identical symbol under each one. That symbol can be anything other than the Scatter.

Bonus Features

Free Spins
- The Free Spins come with an unlimited Win Multiplier. The multiplier begins at x1 the bet and increases by one every time you land a winning combination. During the feature Bonus symbols will award an additional Free Spin.

Before the Free Spins begin you can choose to gamble those spins in a chance to win more Free Spins. The chance of winning will be displayed for you on the wheel that you need to spin.

Jackpot King Deluxe
– The Jackpot triggers at random. When it does you will be taken to a new set of reels where the only symbol you can land is a “Crown”. Every time you land one it will stick in place and you will be given a respin. If no additional “Crown” lands on the reels the feature is over but as long as you keep landing new symbols you will keep getting respins. The feature will end either when you do not land a “Crown” symbol or when the board is full. The number of symbols you land will determine the size of the jackpot with 15 or more needed to spin the “Wheel King”. If you can manage this then you have the chance to win the slot’s progressive jackpot.


Mighty Griffin Megaways is a decent looking BluePrint Gaming slot. As I said in the theme section it does look a little on the generic side, but still one that has a certain appeal. You get the usual array of Megaways features, from the Free Spins with the win multipliers, to the mystery symbols. The maximum number of Megaways and the additional reel mean it is the full on Megaways experience and you also get a Jackpot with the chance to trigger the Progressive Jackpot. The house edge is nothing to get very excited about and it is worth noting that without the jackpot your value for money in the long run is not great.
