Diamond Miner DuoMax Slot Review

Grab your pickaxes and torches, and get ready to head down into the mines once again with the Diamond Miner DuoMax slot from Reflex Gaming. Released as part of the Yggdrasil partner program, the slot, as its name suggests, utilizes the DuoMax feature, which provides two separate multipliers as you play. Join me as I tunnel down and discover if this slot is worth spinning in this Diamond Miner DuoMax slot review.

Diamond Miner DuoMax Online Slot Layout, Theme and Setup

In Diamond Miner DuoMax, we are dropped right into the middle of a mine, with the reels dominating the bulk of the screen. To the side of the grid, you will see a little prospector strapping up some dynamite while bars of gold and silver and giant barrels and wagons full of crystals and diamonds make up the symbols. 

I found the design to be fairly basic but functional, but the game has a slightly aged feel. Some animations help to bring the action to life, while the soundtrack is much more upbeat than the game’s theme would have suggested. 

A sub-standard maximum win and a fairly basic design leave the slot feeling fairly forgettable, while the cluttered game screen makes the game feel a little dated and messy.

How to Play Diamond Miner DuoMax Online Slot

The base game for the Diamond Miner DuoMax slot keeps the action straightforward. The game is played on a 5x3 game grid with 243 ways to win active on every spin. Wins are formed when players land three or more matching symbols across the grid on consecutive reels, regardless of position. 

I thought the game screen was quite cluttered, with the Buy Bonus slots and Golden Bet options to the side of the grid, as well as the aforementioned two multiplier trails.

Diamond Miner DuoMax Online Slot Free Spins, Bonus Features, & Bonus Buy

Much of the focus in the Diamond Miner DuoMax slot is on the titular feature. This consists of two sets of multipliers that sit on either side of the grid. The one on the left is applied on wins left to right, and the one on the right is vice-versa. 

The slot uses a Dropdown mechanic, with winning symbols removed and new ones added. When this happens, the respective multiplier increases by one on the trail. The multipliers are reset when no new wins are formed, ending the sequence. 

Wins can also be randomly rewarded thanks to the TNT Bonus. This triggers at random, removing a column of symbols and letting new ones fall in, guaranteeing a win and triggering a Dropdown. 

Consecutive wins are also counted above the reel. Every fourth Dropdown win will trigger the Big Blast Bonus. Players will randomly be given one of the following features: 

  • Double Wild: Two Wilds are added to the grid. 
  • Wild Stack: A stack of six Wilds is added. Three are in view, with the next three revealed following a Dropdown. 
  • Multiplier Boost: Both multipliers are boosted by 10. 
  • Extra Life: A non-winning Dropdown will be cleared, and another drop will take place.

Finally, landing three or more Scatters will trigger the Diamond Miner DuoMax Free Spins round. Three, four, or five Scatters will reward seven, nine, or 11 spins, respectively. There is also a gamble feature at the start of the round. During the spins, the Multipliers do not reset. 

Players can also trigger the Free Spins by using the Buy Bonus feature. You can enter the round for 100x your stake or get 16 spins for 300x. 

My Experience Playing the Diamond Miner DuoMax Slot for Real Money

I took Diamond Miner DuoMax slot for a spin on my laptop and iPhone. I found the game’s screen to feel very cluttered, and I felt this even more on my mobile. It seems the developers might have taken the claustrophobic nature of thegame’s setting a little too seriously. 

The slot can be played for stakes between $0.20 and $100, which I consider the standard betting range for most top online slots. I recommend playing the slot for free using the Diamond Miner DuoMax demo provided to give you an idea of how the game works and whether you want to play for real money. 

The Buy Bonus option is also very useful in this regard. I recommend triggering it when playing for free to avoid waiting to launch the bonus rounds.

Diamond Miner DuoMax Slot RTP, Maximum Payout & Volatility

Diamond Miner DuoMax has a fairly average math model that is not likely to get players too excited. The RTP is solid at 96%, with the game being rated highly volatile. The maximum win is 5,000x your stake, which is a little underwhelming. 

Diamond Miner DuoMax Slot Verdict and Recommended Games

Diamond Miner DuoMax is a very middle-of-the-road slot game. Some of the elements, such as the Big Blast Bonus, add some excitement to the gameplay, and the DuoMax Multipliers can spice up the bass game considerably. 

However, a sub-standard maximum win and a fairly basic design leave the slot feeling fairly forgettable, while the cluttered game screen makes the game feel a little dated and messy. Overall, if you enjoy the DuoMax Multipliers and want some cascade-centric gameplay, then Diamond Miner DuoMax might appeal. However, if you want big wins and a good design, then it is best avoided. 

If you are a fan of mining-themed slots, there are plenty of classics at top casinos. A personal favorite of mine is Nolimit City’s Dead Canary. I would also highly recommend Fire in the Hole 2 by the same developer. Of course, no list of mining slots would be complete without the iconic Bonanza slot from Big Time Gaming.
