Diamond Mine Megaways slot review
Diamond Mine Megaways is Blueprint Gaming’s 2017 expedition into Big Time Gaming’s licensed engine — and the most faithful homage to Bonanza ever struck. Six reels of shifting heights deal up to 117,649 ways, wins cascade away, and the free spins run on the same beloved fuel: a win multiplier that climbs with every reaction and never resets. Released in the licensing wave that followed Bonanza’s breakthrough, it proved the engine travelled — and for many UK players it was actually their first Megaways game, encountered on bingo-side sites before the format conquered everything.
How Diamond Mine plays
Gems lead the paytable above the card royals, with a miner’s dynamite wild lending a hand, and an extra horizontal reel above the grid adds four more symbols to the middle reels each spin. Winning symbols are blasted clear and replacements tumble in, so one stake can chain a sequence of cascading wins before the dust settles.
Scatters and the unlimited multiplier
Spelling out the scattered letters opens the mine: free spins begin with the multiplier at 1x, and every cascade during the round raises it by one, without cap and without reset, for the duration. Long chains late in the feature — multiplier in double figures, premium gems tumbling — are where the game pays its debts to Bonanza most handsomely. Additional scatters during the round extend the digging.
RTP, volatility and top wins
The commonly published RTP is around 96.4%, with operator versions varying — the in-game information panel shows the live figure. Volatility is high in the classic cascade-Megaways mould: patient stretches punctuated by feature runs whose ceiling stretches comfortably into four figures times stake and beyond.
