Diamond Mine Megaways Slot – Free Demo

A Wild that never touches the six reels

A Wild in Diamond Mine Megaways can only land in the four extra positions above reels 2 to 5, so the six reels themselves never hold one. Dig in, this Blueprint Gaming slot is a callback to the era when a treasure was something you swung a pickaxe at. Underneath the theme it is the Megaways engine, licensed from Big Time Gaming, with six reels showing up to seven symbols each. It has a mining theme, so it revolves around the diamond seam and the dynamite employed to get at it. Coincidentally, prospecting was always a wager. My own dig ran 291 spins at a 5-credit stake. It's astonishing to think what an aged miner would make of himself featured in an online slot a century or so later, but it is the Megaways engine it is best known for, in particular the cascades and the multiplier that ascends with them in free spins, and that is also central to the story in this slot. Of those 291 spins, 54 paid, and 31 of them paid less than the 5 credits they cost.

Reel heights decide the ways total

Diamond Mine Megaways is a highly volatile slot. My longest stretch without a win was 22 spins, ending on spin 142. It arrives with a random-reveal symbol in the base game as well as a free spin feature, and that feature incorporates an unlimited win multiplier. Nothing in the base game carries a multiplier; it exists only inside the round.

Visually, it's a slot simple to recognize as a Blueprint Gaming slot with it's distinctive interface and visuals, and it has a subterranean feel with the reel set bordered by stone and wood, situated in what seems to be a mine. Each reel shows anywhere up to seven symbols, and the ways total on a spin follows from whatever heights land. The visual production is comparatively simplistic, at least when it comes to the base game. An extra row of four positions sits above reels 2 to 5 and feeds into wins on those reels. There are some intriguing new features at play. It still comes across as quite a conventional slot with it's 6-reel, up to 7-row and 117,649 ways to win arrangement, though nothing amiss with that. The 117,649 is a ceiling rather than a normal state, and it needs all six reels landing at their full seven symbols.

Final Minty Score: Everything this game keeps back sits behind one trigger condition, four scatters, and across 291 spins at a 5-credit stake I never met it once. That leaves the base game to carry the whole session on its own, and it returned 455 of the 1,455 credits it was given.

Which symbol is allowed in which position

Diamond Mine Megaways contains a Wild symbol, a Free Spins Scatter, and a TNT symbol, and wins are created by 2 to 6 successive identical symbols from the leftmost reel, at any height. All the combinations that land are added together, and only the highest win is paid per winning combination. The payouts are multiplied by your stake. Scatter wins are paid on top of the reel wins.

The Wild only ever emerges in the additional positions above reels 2 to 5. Scatters do the reverse, landing on the reels but never in that extra row while the base game is running. There it substitutes for everything but the scatters. That leaves reels 1 and 6 as the two a Wild can never help.

A multiplier that only moves on cascades

The TNT symbol can land in the base game. It can appear in any position on the grid. It can reveal the same random symbol on every TNT in sight, though never a scatter. Several of them in view all turn into that one symbol at once.

Winning symbols are cleared. The positions above reels 2 to 5 are replaced from the right. Fresh symbols drop in to replace them, and the cascades recur until no further win is created. One captured frame shows the ways counter reading 18,375 rather than the headline figure, because the reels came in short, with a diamond and a TNT sitting in the row above the middle reels and a 25-credit win paid.

Four Scatters grant 12 free spins. Each additional Scatter beyond that contributes 5 more, and during the round, 3 Free Spins Scatters grant another 5 spins and 4 grant another 10. Those retrigger scatters arrive in the row above reels 2 to 5, which can show them once the round is running. The Unlimited Win Multiplier begins at 1 and rises by 1 after every cascade. A spin that cascades once moves it once, and a spin that wins nothing leaves it where it is. It persists for the entire round rather than resetting between spins, and the stake that triggered the round is the stake applied throughout it. None of my 291 spins got as far as finding out.

What 291 spins bought

It reads as a customary Blueprint Gaming slot, in spite of the somewhat inventive free spin feature and distinctive backstory, and it doesn't feel like there was too much ambition invested in making it stand out or for it to break new ground. I peaked at 1,082.50 credits on spin 9 and never got back to the starting balance after that. Even the max win potential of 10,000 times the stake is ordinary. My largest single win was that spin 9, 125 credits, 25 times the stake. By the way, I saw no trace of that across 291 spins at a 5-credit stake - not one free spins round triggered, 54 paying spins in total, and a 1,000-credit balance gone by the finish with 455 credits returned. Behind spin 9 the best of them were 25, 23, 22 and 21 credits, against 1,455 credits wagered.

It's not a poor slot in any way. The one part of it I never watched run is the multiplier, because the trigger condition never came in. The studio has since put the same seam through Diamond Mine Extra Gold, which sells entry to the round outright, and through the smaller grid of Lightning Strike Megaways. Ultimately I can't help to feel like I'm playing a re-skin rather than something novel and brand new.
