Diamond Mine Megaways All Action (Blueprint) – Review & Demo Play

Introduction to Diamond Mine Megaways All Action

Diamond Mine Megaways All Action skips the base game and throws me straight into the feature. I choose my stake between £20 and £2,000 and I’m off. The setup is the familiar six reels plus a top horizontal reel, with 2–7 symbols per reel and up to 117,649 ways. Cascades hit after every win. The progressive multiplier goes up by 1x with each cascade and, because there’s no base game, it doesn’t reset between spins. The top payout is 10,000x.

Theme, Graphics & Soundtrack in Diamond Mine Megaways All Action

The Wild West look fits the mining angle. I’m staring at a dusty gulch dotted with cacti while cartoon reels sit in front. Symbols lean into the story: diamonds, a grizzled prospector, lanterns, pick and shovel, and the usual royals. Animations are clean, reactions pop nicely, and the top reel keeps the grid feeling busy. It’s easy to read even when the Megaways expand.

The audio is banjo-led and very much cowboy country. I can take it in short bursts, though I tend to knock it down during long sessions. Pace-wise, spins are brisk and cascades roll fast, which suits the feature-first format. If you like a snappy rhythm, it lands well; if you prefer slower spins, it can feel a bit lively.

Diamond Mine Megaways All Action RTP & Volatility

The RTP sits at 96.43%. Volatility, in practice, plays medium to high for me because all value is concentrated in the bonus. The unlimited win multiplier is the engine, and streaky patches are part of the ride. When cascades line up, the meter climbs quickly and the balance can move in chunks. Droughts happen too, given the feature cost. Bankroll planning matters here, as runs of bonus rounds with low multipliers do occur between the better streaks.

Bet Sizes & Paytable Wins in Diamond Mine Megaways All Action

All Action means I’m buying straight into the feature with no spins in between. Stakes range from £20 up to £2,000 per go. Symbol values are toned down versus other Diamond Mine variants, cut by 100x, which suits the feature-only setup. The maths shifts the weight to multiplier growth rather than fat line pays in isolation.

On the paytable, six-of-a-kind pays are as follows: Diamond 0.5x, Prospector 0.075x, Lantern 0.02x, Pick & Shovel 0.02x. The royals from A to 9 run between 0.0175x and 0.008x for six. You still need three to six matches left to right, with the Megaways grid deciding hit frequency. Those lighter base values make sense once the multiplier starts climbing on a hot cascade.

What are the bonus features in Diamond Mine Megaways All Action

Megaways varies reel height on every round, granting up to 117,649 ways. Cascading wins follow each hit, removing symbols and dropping new ones until no fresh combo lands. Every cascade nudges the progressive multiplier up by 1x. Because this is All Action, that multiplier carries on through the whole feature and never resets between spins, which is where the real potential lives.

The Dynamite wild appears on the top horizontal reel and substitutes for regular symbols. TNT Mystery Symbols are barrels that all flip into the same pay symbol when they land, clearing blockers and helping build lines. When mysteries line up with the top reel wilds and a decent reel height, the grid can open right up for a tidy chain.

At the start, I pick one of five dynamite sticks to reveal 8–20 free spins. I can accept or gamble on a wheel for up to 30, but there’s a real chance to drop spins or wipe them, so I tread carefully. During the bonus, landing 3 or 4 gold scatters adds 5 or 10 extra spins. With cascades feeding an unlimited multiplier, the best rounds are the ones that retrigger early.

Our Verdict on Diamond Mine Megaways All Action

I rate this as a straight-to-business take on Diamond Mine. Skipping the base game keeps it punchy, the multiplier that doesn’t reset is the hook, and 10,000x keeps me interested. The dynamite pick and the gamble to 30 add a bit of needle. When TNT mysteries show up with height, it can snowball fast.

There are trade-offs. A £20 minimum is steep, and the symbol values being 100x lower won’t suit everyone. The soundtrack is a love-or-mute affair. If you want no grind and pure feature play with Megaways, cascades, and an unlimited multiplier, this is a solid pick. If you prefer low-stake chipping or base-game ladders, this isn’t the one.
