Let’s dig in—Diamond Mine Megaways, released by Blueprint Gaming back in 2018, is a true classic for Megaways fans. The game still draws crowds, and for good reason: it was Blueprint’s first shot at the Megaways engine licensed from Big Time Gaming, and you can really feel that heritage in every spin.
This slot keeps pulling players in with its straightforward, time-tested mechanics. Even after all these years, the gameplay stays fresh, especially because of that signature win multiplier in the free spins round—it’s what really sets Diamond Mine apart from the Megaways pack.

In short: you’re looking at a mining-themed, high-volatility Megaways slot with a climbing multiplier during free spins, a solid 96.43% RTP, and a max win of 10,000x—right where a serious slot should be.
The vibe is pure cartoon Wild West, all pickaxes and dynamite, with a twangy hillbilly soundtrack that’ll stick in your head. Sure, Blueprint has pushed out fancier slots since, but this one nails what matters: a focused bonus structure and a visual style that makes every cascade feel like you’re blasting deeper into the mine.

Bet Range And Game Setup
You can spin from $0.20 up to $100 per spin, so whether you’re on a shoestring or ready to up the ante, there’s a stake for you. Adjusting your bet couldn’t be easier—just tap the Bet button on the left and cycle through your options.
There’s no bonus buy or bonus bet in Diamond Mine Megaways. You’ve gotta trigger the free spins the old-fashioned way—by landing those scatters. Some folks might miss that, but honestly, it keeps the suspense alive.
Reels Rows And Ways System
Gameplay-wise, you’ve got 6 reels, plus a horizontal reel running above the main grid. Each main reel can land between 2 and 7 symbols, and when everything maxes out, you’ll hit the full 117,649 Megaways. That ever-changing ways-to-win count? It’s what makes the Megaways engine so addictive.
Payouts run left to right, starting from reel 1, and the more symbols you see, the crazier your win potential gets. Every spin feels a little different, and that’s half the fun.
Availability Of Demo Mode And Autoplay
You’ll find Diamond Mine Megaways demo mode at most online casinos and review sites. I always take a few demo spins first—why risk cash before you know the rhythm?
Autoplay is in the mix too, unless you’re in the UK. Set it for 10 to 100 spins, and you can add win/loss limits if you want to keep things under control. The paytable’s always just a click away, so you can check symbol values or features on the fly.
How The Game Plays Spin To Spin
Theme Visual Identity And Symbol Set
Diamond Mine Megaways drops you right into a dusty underground mine, and the Wild West vibe hits you immediately. Rocky canyon walls frame the reels, and there's this twangy, playful hillbilly soundtrack that loops in the background—honestly, it keeps the mood light and totally fits the prospector theme.
The visuals? Bold and cartoon-bright, not overly fancy, which I love because it keeps everything crisp and readable, even when the action gets wild. Spotting wild and scatter symbols is a breeze, which matters when the reels are firing off cascades left and right.
Symbols split into two groups. Low-value card royals—9 through Ace—fill out the bottom end of the paytable.
High-value icons bring in the real mining flavor: a pickaxe and spade, a lantern, the grinning diamond prospector, and of course, the sparkling diamond gem. That diamond is your top prize, paying a hefty 50x your total bet for six across the reels. It feels amazing to land a full line of them, trust me.

Ways To Win And Cascading Behaviour
This is where the game really gets its teeth. Diamond Mine Megaways can crank up to 117,649 ways to win, thanks to that classic Megaways reel engine.
Instead of old-school spins, you get cascading wins. Land a winning combo? Those symbols explode in a shower of dust, and fresh ones drop in from above, filling the gaps.
Every new cascade brings a fresh shot at another win, and this keeps going until you hit a dead end. The tension builds with each drop—sometimes you’ll chain together a handful of wins off a single spin, and that’s a feeling you don’t forget.
Each cascade gets evaluated on its own, so you can rack up a nice sequence if the reels line up just right. In the base game, there’s no multiplier climbing with these cascades, but they can really stretch out a hot streak.
Wilds Mysteries And Base Game Flow
The dynamite wild is your go-to substitute, standing in for everything except the scatter. It only lands on the horizontal reel above the main grid, so it can drop down and impact multiple reels at once—love that little burst of excitement when it happens.
The TNT barrel brings the mystery. When you land a few TNT barrels, they all morph into the same random symbol before wins are calculated. Could be any regular pay symbol or even the dynamite wild, but not the scatter. Sometimes, what looks like a dud spin suddenly explodes into a monster win if the TNTs line up just right.
The sack of gold is your scatter. Land four or more and you’re off to the free spins round, which is where things really heat up.
Diamond Mine Megaways Bonus Features And Win Potential
How Free Spins Are Triggered
Chasing the free spins? You need four or more sack of gold scatters in one spin. Every bag of gold that drops feels like a mini heart attack, especially when you’re at three and waiting for that fourth to land.
You get 12 free spins to start. The Megaways setup shuffles on every free spin, so you never know if you’ll get a skinny or fat reel layout. That randomness keeps every bonus round fresh and unpredictable.
No bonus buy here. You’ve got to grind it out and hit scatters naturally. I’ll be honest, with the game’s high volatility, those bonuses can feel rare, but when they finally drop, it’s a rush.
Increasing Multiplier Mechanics
This is where the magic happens. Free spins come with an increasing multiplier that starts at 1x and bumps up by 1 with every cascade win—no ceiling, no limits.
If you hit three cascades in a spin, the multiplier jumps by three. It can get wild fast, and that’s what gives this slot its monster win potential.
The unlimited multiplier is the real engine here. If you catch a lucky run of cascades, especially with a high Megaways count, you can push the multiplier into silly territory. That’s how you chase the 10,000x max win. Sure, it’s rare, but it’s not impossible—and I’ve seen some epic runs.

Retriggers Bonus Extras And Missing Features
Don’t expect retriggers here—once your 12 free spins are done, that’s it for the bonus round. There’s no way to earn more spins mid-bonus, no matter how many scatters you land.
No bonus buy, no pick-and-click, no progressive, no hold-and-spin. The game keeps things lean and focused: just cascading wins, mystery symbols, and the uncapped free spins multiplier. Some players might miss the extra layers, but if you love a pure, streamlined bonus with big win potential, this one nails it.

How It Stacks Up Against Bonanza And Blueprint Peers
Bonanza Megaways from Big Time Gaming is the obvious comparison—mining theme, horizontal reel, cascading wins, and the Megaways engine all match up. RTP is in the same ballpark, and both have similar max win ceilings.
Diamond Mine Megaways feels simpler in its bonus structure—no retriggers to keep track of—but Bonanza does let you boost your free spins with extra scatters during the bonus. That’s a plus for some, but I kind of like the straightforward approach here.
Compared to newer Blueprint Megaways slots like King of Cats, Diamond Mine shows its age a bit. King of Cats packs in more features, sure, but Diamond Mine wins on theme and just how easy it is to jump in and play. For anyone new to Blueprint’s Megaways lineup, this is a fantastic first stop—and for seasoned spinners, it still has that satisfying, high-volatility punch.

|
10,000x max win |

Cons
|
Disadvantage |
Detail |
|---|---|
|
No bonus buy |
You can’t buy your way straight into free spins. That means you’ve got to grind it out and trigger the bonus naturally, which—at this volatility—can test your patience and your bankroll. |
|
No retrigger mechanic |
The game gives you 12 free spins, period. There’s no way to grab extra spins once you’re in, so you’ve got to make those rounds count. |
|
Hit frequency not disclosed |
Blueprint doesn’t publish the hit frequency, which always bugs me. Without that info, planning your session or sizing bets becomes a bit of a guessing game. |
|
Limited feature depth |
Don’t expect pick-and-clicks, hold-and-spin, or jackpot features here. Compared to some of Blueprint’s flashier releases, this one’s a little stripped down. |
