Diamond Mine online slot game

117,649 ways to win, Diamond Mine from BluePrint Gaming is an online slot that offers something different from each spin of the reels. It has randomly sized symbols which could mean between 2 and 7 symbols per reel while cascading symbols, a free spins round, and mystery symbols will all play a part in bringing you payouts.

Theme and Story Line

The mining theme might have been done to death when it comes to online slots but it does seem to be a popular one. The central character is a miner and he is hoping that you can give him a helping hand in finding him some riches while you are likely to be hoping to find some for yourself too.

Graphics, Sounds, and Animations

The graphics on Diamond Mine will not win any awards but they are fairly decent and provide just enough quality to be pleasing on the eye. You get the feeling that this is an online slot that has been optimized in such a way that it is guaranteed to run smoothly on a wide range of devices. 

In the background, you have cactuses and the rocky mountains where the chief character is hoping to find his haul of diamonds. The reels are the mine itself and the symbols are colorful if not a little basic. As for animations, there are not really many apart from the reels spinning and the cascading symbols exploding after every win.

The soundtrack is about as country as you can get and you hear the miner chipping away at the rocks in the background. All sound can be turned off if it starts to get annoying.

The gameplay on Diamond Mines changes with every spin of the reels thanks to cascading symbols, a 6x7 reel format, stacked symbols, the Megaways feature, and the different sized symbols. The latter in particular is what makes this slot what it is. One reel could have as little as two symbols while another could have as many as seven.

All of the above means that on any given spin, players could have as many as 117,649 ways to win. Winning combinations are made as long as there is the same symbol anywhere on three or more consecutive reels starting from the 1st reel. The more symbols present means larger payouts. Additionally, due to cascading symbols, winning combinations disappear and allow other symbols to drop into place. This gives the potential for further combinations to be formed.

There are 12-standard symbols on the reels of Diamond Mine and as you might expect, the Diamond is the best paying of these. It is worth 50x the total spin bet when landed in a 6-symbol winning combination. In a 5-symbol combination, it will pay out 25x the total spin bet, 10x for 4 symbols, 5x for 3 symbols, and this is also the only symbol to payout when found 2 times with a reward of 2x being awarded for that.

The miner, a lantern, and a pickaxe/spade combination are the remaining high-paying symbols. As for the lower-paying symbols, these are the A, K, Q, J, 10, and 9 playing card symbols.

The ‘Dynamite’ symbol is the wild symbol on Diamond Mine and this can substitute for all symbols apart from the ‘Sack of Gold’ scatter symbol.

Bonuses and Free Spins

A free spins round is the main bonus feature on Diamond Mine and this is triggered when a player lands at least four ‘Sack of Gold’ bonus symbols anywhere in view. Players are awarded 12 free spins for landing those four symbols but they will also get an additional 5 free spins for any additional symbols that were found from the triggering spin.

During that free spins round, players will be able to enjoy an unlimited win multiplier. Each time they find a win during a spin, that multiplier increases. Starting at 1x, any further wins due to cascading symbols will see that multiplier increase. Also, find three or four of those Sacks of Gold symbols on the top reel and players will land an additional 5 and 10 free spins respectively.

Another feature is the Mystery Symbol feature that occurs both in the base game and during the free spins round. The ‘TNT Barrel’ symbols which usually appears stacked will all explode and turn into the same random symbol from the reels. This can lead to further surprise wins.

Bet sizes, RTP and Variance

Due to the reel format and the 117,649 potential pay lines on each spin, betting on Diamond Mine has been made as simple as possible. You will not be able to configure how many pay lines to wager on or the number or values of coins and instead simply choose an amount to bet on each spin. This can be anywhere between 0.20 and 100.00 per spin.

Diamond Mines has a respectable 96.43% RTP and is a high variance slot. The latter means that payouts are not as frequent as you will find on many other slots but generally when they do come in, they are big. For that reason, this is a slot for players with good bankroll management skills and a bit of patience.


Diamond Mine is certainly a fun video slot and one that really does offer the player plenty of different ways to make their money. A free spins feature with unlimited increasing multipliers is where the biggest wins will come but cascading symbols, a randomized reel format, and wild symbols will also add to the enjoyable experience when playing Diamond Mine.
