Review of Diamond Mine

Played over 5 reels, the Megaways (licensed by BTG) platform provides up to 117, 649 ways to win. Each spin can offer a different number of paylines on the reels because the columns randomly hold a different number of symbols with every spin. All wins are calculated from the leftmost real to the right. Match three or more symbols anywhere on consecutive/adjacent reels to reap rewards.

You can play a round for between 0.20 and 100 per spin and win a maximum line win of 50x the total stake per combination. The medium game variance combines with a 96.43% RTP to pay out a really nice mixture of wins; from small ones to very high ones. The main feature is where most of your wins will be made, though.

Diamond Mine Theme, Soundtrack and Symbols

We have seen mining themed games before, though this is a first on the Megaways platform and so remains unique to a degree, yet we can’t help but notice close familiarities between this game and Pragmatic Play’s Gold Rush slot. Many of the game symbols are the same concept with a slightly different design. The cartoon style of the game provides for a fun loving and quirky slot experience that holds some upbeat entertainment.

The reels are placed in a wooden frame at the mouth of a mine shaft with the Western American deserts looming in the background. Prospecting and mining was a common practice among many Americans in the Wild West, and often provoked many skirmishes between miners. Find gold or diamonds in this game and you may truly reap the rewards in cash. Roll the reels to the tune of the banjo strums and hold thumbs for a win. 

The gaming symbols bolster the theme of the game pretty well until you come across the lower end symbols. Here, Blueprint Gaming have run the course along with many other slot game manufacturers, to use plain card deck symbols (9, 10, J, Q, K, and A). It’s a commonly accepted practice, so who are we to differ on this. 

The higher value symbols consist of thematic icons, which include: A big shiny diamond, a bearded prospector, a lantern, and a shovel and pick symbol. The game scatter and feature trigger is a bag of gold nuggets and the game WILD is a stack of dynamite explosives. The Wild symbol will substitute for all of the standard game symbols to help produce winning combinations. There is also a mystery symbol that is represented by a barrel marked as TNT, but more on this one later.

Special Features

Much to the appeal of prominent modern slot players, this slot title carries a fair variety of special features to keep players interested. These include a cascading reel engine, mystery symbol addition, and the main free spin bonus round feature.

Cascading Reels

When a winning combination is formed, something special happens on the reels. The symbols involved in the combination disappear from sight, leaving gaps in the reel grid. This symbols above then cascade/tumble down into position to close up all the gaps on the screen. This action thereby effectively gives you another chance at completing more winning combinations. As long as wins are made, the reels will continue to cascade.

TNT Mystery Symbol

When the barrel of TNT lands anywhere on the reels, it will transform into a matching symbol to attempt to create a winning combination along with other standard symbols. It works much like a WILD symbol does in this respect. The fact that this game already has a separate Wild symbol as well, means that there are many ways to reap better wins in the base game.

Main Feature: Free Spin Bonus Round

Many of the best wins will be made in this round and so you should eagerly be on the lookout for Bags of Gold scatter symbols on the screen. Land 4 or more bags to trigger free spins. 4 triggering scatters grant you 12 free spins, while every extra triggering scatter over and above that adds another 5 free spins to the initial tally.

Subsequent to this, the bags of gold will only appear in the top 4 blocks above the reel set. Land 3 or 4 bags in this row and be awarded 5 to 10 extra spins respectively. The cascading reels remain in effect in the feature, but now a multiplier will be implemented on consecutive spins, increasing by 1x with every tumble of the rollers.


Because betting is not calculated per line played, due to the Megaways pay engine, each wager covers the entire reel set. For this reason, wins are calculated on total bets and not line bets. The maximum win on any one combination of 6 symbols matched across the reels is 50x total stake for the precious diamond icon. This presents a win of 5,000 on the maximum 100 wager. Because more than one combination can be paid out in one spin of the reels, the maximum exposure available on a single spin with cascading multipliers intact is around 250,000.

Game Verdict

For those seeking the thrills of the Wild West from a different angle to the common gunslinging and bank robbing slots, try Diamond Mine. The medium variance offers a great balance of low to high-end payouts.

Cascading and Megaway reels are a great combination engine that promises more than average reel action, while the added multipliers in the free spins round are sure to show on your bankroll. If more traditional reel rolls and paylines are your fancy, then please try Pragmatic Play’s Gold Rush slot game. Though the game variance is on the higher side, the 5 reels and 25 paylines (with betting increments of between 0.25 and 250) may be more to your liking.
