Diamond Mine Extra Gold Megaways is Blueprint Gaming's first follow-up to its original Diamond Mine Megaways release, sticking closely to the look and feel of its predecessor while carrying the same wild-west mining theme through into a bigger Megaways ways-to-win ceiling.
The visuals barely deviate from the original — the same cactus-and-rock desert backdrop, the same rickety wooden scaffolding holding the reel grid together. Diamond Mine Extra Gold Megaways runs the mechanic at its maximum setting: 6 main reels each capable of holding up to 7 symbols, plus a 4-position horizontal reel across the top, generating as many as 117,649 ways to win when everything is fully stacked. Wins form from matching symbols landing on the same reels regardless of row position, and a cascading feature clears winning symbols to make room for new ones, chaining further wins where the reels cooperate. The paytable sticks to a wild-west mining cast — 9-through-Ace card values styled to match the theme, backed up by a shovel-and-pickaxe icon, a lamp, and a Santa-esque prospector character carrying the bigger payouts.
Diamond Mine Extra Gold Megaways returns 96.43% to players over the long run, a genuinely strong figure that sits comfortably above the market average and marks it out as one of the more generous entries in the wider Diamond Mine series.
Rated high volatility, the game leans on its cascading mechanic to generate the bigger moments — a single triggering spin can chain into several consecutive wins as symbols clear and refill, with the payout building each time the reels cooperate. That structure means results can vary considerably session to session, with quieter stretches offset by the occasional extended cascade run that makes the wait worthwhile.
The maximum win reaches 10,000 times the stake, a strong ceiling consistent with the wider Megaways category. Stakes run from 0.20 up to 100 per spin, giving a solid range for both cautious and more confident players to find their level.
Diamond Mine Extra Gold Megaways plays it safe by sticking closely to what made the original popular, leaning on a maxed-out Megaways ways-to-win count and cascading wins rather than reinventing the format. With a strong 96.43% RTP, high volatility, and a 10,000x ceiling, it's a solid choice for players who enjoyed the first Diamond Mine and want more of the same wild-west mining action.
