Diamond Mine Megaways is Blueprint Gaming’s first crack at the Megaways format, released back in October 2019, and it still holds up surprisingly well. This slot runs on a 6-reel Megaways layout with 2 to 7 symbols per reel, giving you up to 117,649 ways to win on a fully expanded spin. There is no jackpot attached here, but the numbers are still serious, with a maximum win of 10,000x your stake. Bets range from £0.20 to £40, volatility sits in the medium-to-high bracket, and the game leans on cascading wins, free spins, and a growing multiplier rather than gimmicks to do the heavy lifting.



Diamond Mine Megaways sticks to the classic Megaways blueprint. Six reels, with anywhere between two and seven symbols dropping on each reel every spin. When everything lines up at full height, you are playing with up to 117,649 ways to win. There are no paylines to adjust. Wins simply land by matching symbols across adjacent reels from left to right.
The wagering range is sensible and easy to work with. Bets start at £0.20 per spin and run up to £40, which keeps it accessible without limiting players who want more bite. There is no coin value juggling either. Set your stake and spin.
RTP sits at a healthy 96.43%, which is comfortably above average for a Megaways slot and one of the reasons this slot game has aged well. Volatility leans medium to high, so wins arrive often enough to keep things moving, but the bigger moments usually come from cascades during free spins. The maximum win is capped at 10,000x your stake, achieved through stacked reactions and multipliers rather than a single lucky hit.
There are lots of different online casinos where you can play Diamond Mine Megaways. Here is my pick of the best slot sites:



Diamond Mine Megaways drops you straight into a dusty Wild West mining site. Think rocky tunnels, bright desert skies, and a grinning miner who looks far too cheerful for someone working underground. Blueprint keeps the visuals clean and colourful, with chunky symbols that stay clear even during long cascades. A light country-style soundtrack hums away in the background, doing its job without stealing attention.
Symbols follow a clear hierarchy. Low-value icons are card ranks from 9 through Ace. Higher-value symbols include mining tools, a lantern, the miner himself, and the diamond. The diamond is the top-paying standard symbol, worth up to 50x your stake for six of a kind. The Wild appears as crossed diamond sticks and substitutes for all regular symbols. It only lands on the horizontal reel above reels two to five. The Scatter is a bag of gold, which pays anywhere and triggers free spins. A TNT barrel acts as a Mystery Symbol, transforming into regular symbols to boost reactions.

Diamond Mine Megaways behaves itself on mobile, even though it dates back to 2019. Blueprint built it on HTML5, and it shows. The Megaways grid scales cleanly, with symbols staying sharp and readable on smaller screens. Bet controls collapse neatly, the spin button sits right where your thumb expects it, and cascades play out smoothly without hiccups. The horizontal reel above the main grid stays visible without crowding the screen, which matters during busy reaction chains. Overall, it feels stable, predictable, and easy to play on both phones and tablets.



Diamond Mine Megaways keeps its feature set focused and effective. There are no side quests or progress meters here. Everything revolves around reactions, mystery symbols, and a free spins round that can snowball fast if things line up. The free spins feature is easily the main attraction in terms of winning potential.
The Reaction mechanic is active in both the base game and free spins. Any winning symbols disappear, making space for new ones to drop in from above. If another win forms, the process repeats. These chains can build decent totals over a single spin, especially on full-height Megaways drops. It is simple, but it does a lot of work behind the scenes.

Mystery Symbols appear as TNT barrels and can land on any reel. When they hit, they transform into one of the regular paying symbols, excluding the Scatter. Multiple Mystery Symbols on the screen can turn an average spin into a strong one, particularly during reactions when fresh symbols keep dropping.

Free spins trigger when four or more Gold Bag Scatter symbols land anywhere on the reels. Four Scatters award 12 free spins, with extra spins added for additional Scatters. During free spins, an unlimited win multiplier starts at 1x and increases with every reaction. More Scatters during the feature add more spins, giving the round real staying power and access to the game’s biggest wins.
I remember when this one first dropped. Megaways was still fresh, Blueprint was testing the waters, and Bonanza clones were everywhere. Diamond Mine Megaways could have been forgettable. Instead, it stuck. After revisiting it properly, I can see why it still gets mentioned. The pacing feels right. Reactions keep things ticking without dragging, and the free spins round has that slow-build tension I always look for in Megaways slots. It does not scream for attention. It just gets on with the job. Compared to newer Megaways titles that throw modifiers at you every spin, this feels calmer, cleaner, and oddly more satisfying over longer sessions.
I rate Diamond Mine Megaways a nine because it balances value, flow, and win potential better than most Megaways games from its era. The RTP is strong, the mechanics are easy to read, and the free spins multiplier can carry a session without feeling forced. It is not the loudest or wildest Megaways slot out there, but it is reliable, well-built, and still enjoyable years after release. That kind of staying power earns respect.
