Diamond Miner Duomax Slot Review

If you love to see abundant gems and precious metal bars in video slots dedicated to a popular mining theme, that's the eligible gamble. Besides the engaging plot, there are unlimitedly growing multipliers for both win ways, left-to-right, and vice versa, landing after each win Wilds, and several Big Blaster bonus functions triggered in a random order due to several wins in a row. On top of that, there are Free Spins present in this slot with all the features above, including the win multiplier, which is steadily growing until the very end of the Bonus Game, simplifying the challenge of getting the max win of x5,000 to the stake. Let’s see how exactly all that works!

Diamond Miner Duomax Bonus Features

There are a lot of bonus features in this slot, within the Base game, and in the Bonus one. Let’s learn all the details concerning them.

Wild

This special symbol substitutes any other picture, allowing you to form winning combinations using not just identical pics. The only exception is the Bonus symbol, which can not be replaced. Yet, Wild isn't a paying symbol by itself. There could be more than just one Wild on the play grid. This special symbol is present within the Base and Bonus Game.

Avalanche feature

Each winning symbol of any prize sequence, including Wilds, is eliminated after the win is credited to the balance to set free space for new paying pictures falling from above. Also, one Wild is added to the playfield after every single win. All of that helps increase the number of consecutive wins, considerably elevating the chances for big cash prizes.

Duomax™

There is the Multiplier Trail on both playfield sides, from the left and right, each triggering due to wins starting with the corresponding side since there are two possible ways of lining up pay lines — left-to-right, and vice versa, right-to-left. Each winning cascade that happens makes the corresponding Multiplier Trail one-level advancing, guaranteeing to apply a bigger Multiplier to the following potential win. Within the Base game, the Multipliers of both such Trails necessarily reset to the x1 value before the new round starts.

Big Blast Bonuses 

After 4 successive wins in the Base Game and 3 wins in a row within the Bonus Game, you're allowed to get one out of as many as four Big Blast bonuses. Each time this condition is met, one of those activates in a random occurrence.

  • Double Wild

Every time this function is triggered, instead of a single Wild, two such special symbols are added to the play grid just after the previous winning symbols’ elimination.

  • Multiplier Boost

Due to this bonus activation, all the multiplier values of both Multiplier Carousels are increasing by +10.

  • Wild Stack

This function delivers 6 vertically positioned one above each other Wilds, 3 of which immediately fill the randomly chosen reel. The other 3 will appear on the same reel after those first 3 Wilds are dismissed, thanks to the Avalanche feature because of partaking in a winning combination.

  • Extra life

Triggering this bonus delivers 1 Extra Life, which will be used when, at some moment, there are no more winning combinations on the play grid. In this case, the Extra Life will spent, and all the symbols, except Wilds and Bonus ones, will disappear, allowing to fill the playfield with new ones, providing, in this way, a chance to continue the win cascades without resetting the current Multiplier to the initial x1 value. If necessary, such an action will be repeated as many times as many Extra Lives currently in your possession.

TNT Bonus Feature

If there are no wins on the screen, there is a chance that the miner in his TNT cart blows up all 3 symbols on any occasionally chosen reel, guaranteeing the winning combination follows.

Bonus Symbols

It needs at least 3 Bonus symbols to trigger the Bonus Game, yet the more such special pics in view on the playfield, the more Free Spins awarded:

Free Spins Gamble

Before the Bonus Game starts, there is an opportunity to get more Free Spins. You will have a chance several times in a row to gradually increase their number up to 9 Free Spins, 11 Free Spins, and, at last, 16 Free Spins, as many as 5 Free Spins more than it is possible to get standardly. Any loss will lose all the currently available Free Spins.

Diamond Miner Duomax Slot - Free Spins Gamble

Win or defeat is determined randomly using an arrow, rotating within the circle with two sectors colored red and green. If the arrow stops, pointing at the green segment, the number of Free Spins in your possession will increase. Otherwise, you will lose the chance to take advantage of them. Use the 'Gamble' button to try your luck to increase the number of Free Spins, or push the 'Collect' one to start the Bonus game without any risk of losing currently available Free Spins.

 

Your chances to win Free Spins using the Gamble Feature are the next ones:

7 to 9 Free Spins

61.97%

9 to 11 Free Spins

69.47%

11 to 16 Free Spins 

49.04%

Free Spins

Free Spins retriggering isn't provided during the Bonus Game. Free Spins have all the same bonus features as in the Base Game. Due to that, there is no other difference between Bonus and Base game modes except that the Win Multipliers within Free Spins don't reset to the initial x1 value till the very end of the Bonus Game.

Buy Free Spins

You can use the ‘Buy Free Spin’ option to start the Bonus Game at any moment. There are two possible choices:

  • Random Free Spins’ (x100) delivers the Bonus game with a random number of Free Spins (7, 9, or 11).
  • Super Free Spins’ (x300) guarantees the Bonus Game with the maximum possible number of Free Spins — 16.

After choosing the ‘Random Free Spins’ option, the Gamble feature is also eligible, allowing you to increase the number of purchased Free Spins up to the maximum of 16.

Golden Bet

Also, you can crucially elevate the chances of Free Spins triggering by enabling the ‘Golden Bet’ function. It will cost you x0.5 of the current bet.

Our Experience Playing Diamond Miner Duomax

Also, we played a 300-spin session in this slot using a €1 stake and €200 deposit, earning as much as €665.3. Let’s explain in detail how exactly we’ve achieved such an impressive result. But first, it's probably worth clarifying it was the game’s version with an RTP of 96%.

 

During the 1st hundred spins, we got two big wins thanks to 9 consecutive wins, getting the max multiplier of x56, which earned us a total €92.5. Also, there were 28 regular wins, most of which (20, to be precise) were less than the stake. As a result, after the 100th spin, there was €209.6 balance.

Within the 2nd hundred spins, the two biggest wins were €33.9 and €18.55. Luckily, we also got this time the FS triggering due to 3 Scatters landing on the reels. Fortunately, we were lucky enough to increase the Free Spins number to the maximum possible 16 through the Gamble feature. As a result, these brought us as much as €732.7 thanks to the steadily growing multiplier, which reached the gigantic x147 value. The number of Base Game wins was 20. Upon the 200th spin, we had €924.4 balance.

The last hundred spins didn’t provide us with FS triggering. Moreover, the number of regular wins also drastically decreased to just 13, with the max gap between subsequent wins up to 15 spins. But we got a single big Base Game prize of €27.8. As a result, after the 300th spin, we had €865.3. Hence, we made it due to the 300-spin gaming session for as much as €665.3.

There is quite an engaging and original gameplay here with Wilds that add upon each win on the play grid that stimulates winning symbols cascades to continue, which, in turn, grow the Multiplier value of up to dozens and even hundreds, concurrently granting different Big Blaster bonuses for a well-elongated sequence of wins. During the 1st hundred spins, we had at least a couple of times of nine wins in a row, with the Multiplier growing maximally up to x56. As a result, only these two Base Game rounds brought us an overall €92.5. Not bad!

 

On top of that, the TNT Bonus feature sometimes delivers a guaranteed win when there is no prize on the play grid. All that makes the Base Game almost as engaging as the Bonus one. Moreover, there is nothing to distinguish Free Spins from regular spins except for a steadily growing multiplier. Yet, as we demonstrated, that single difference makes Free Spins maximally profitable.

Diamond Miner Duomax Verdict

Here is all you need for fun, engaging, and sometimes even very profitable gambling diversion. Wilds added to the play grid after each win allow you to get many more prize sequences in a row that activate both no-limit Win Multiplier Carousels, which leads to numerous big prizes even within the Base Game. On top of that, there are as many as 4 Big Blast Bonuses over here, awarded in case of several straight wins, also aiming to prolong your win streak. So, it will be thrilling enough to play this game even without Bonus Game triggering. Yet, Free Spins guarantee a tempting Win Multiplier, only growing per every spin.

 

But there are a lot of small cash prizes, elongated pauses between consecutive wins, sometimes reaching even up to 15 spins, not that impressive max win, rarely triggering Free Spins, and no extra FS provided within the Bonus Game. Also, be aware that the RTP value of this slot varies from 96% to 90.5%. But the top-tier version of this slot, as we've shown, can make you happy, granting even just one Bonus Game triggering per several hundred spins.
