Diamond Mine Extra Gold Megways Slot Review

Released February 2020

The Diamond Mine Extra Gold 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 Diamond Mine Extra Gold Megaways is 3.57%.

Diamond Mine Extra Gold 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. The game does not use traditional paylines, instead it operates with a maximum of 117,649 different possible “megaways”, 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 ling as you keep landing wins.

Special Symbols

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

Bonus – The Bonus symbols are the “Gold Bags”. You need to land 4 of them anywhere on the reels at once to trigger the Free Spins feature.

Bonus Features

Free Spins
- If you trigger the Free Spins with 4 Bonus symbols you will be given 12 Free Spins, with every additional Bonus symbol earning you an additional 5 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 only appear at the top of the reels, with 3 earning you 5 Free Spins and 4 earning you 10 Free Spins.

Gamble – Before your Free Spins begin you can choose to gamble by spinning a reel. You will either end up with more or fewer Free Spins than you started with. Once you have done this you can spin again, or press collect to begin the feature.

Golden Bet – This is a pay to play feature that will not be available in all casinos. If you do have the option to use it, it will cost you 50 times the bet and you will automatically trigger the Free Spins feature with 12 spins in total.


Diamond Mine Extra Gold Megaways is a solid addition to BluePrint’s Megaways collection. Like the other Megaways slots in their back catalogue this one looks fantastic. You get the usual mix of cascades, Wilds, Free Spins and multipliers with those Free Spins and that’s as far as your features go other than a Free Spins gamble option. In certain casinos you may also have the chance to pay to play the Free Spins, the cost of which will have to be weighed up before you choose to spend that money. The house edge is offering decent value for money, making this a slot we would recommend.
