Diamond Mine is the first Blueprint Gaming slot which uses the newly-licensed MegaWays pay system from Big Time Gaming. As you've probably guessed from its title, the Diamond Mine slot is a mining-themed mobile game, but what you more than likely weren't expecting is that it offers you as many as 117,649 ways to win!

Start digging for treasure in the Diamond Mine, and you could be lucky enough to unearth free spins, wild substitutions, cascading symbols, and mystery symbols, as well as a top payout of £250,000.

Our Verdict:

Having seen the Megaways pay system used exclusively in Big Time Gaming's White Rabbit, Bonanza, and Star Quest, it's great to see it making an appearance in another software developer's mobile slot.

It means that the Diamond Mine slot game from Blueprint Gaming can give you a myriad of ways to create winning combos, plus it also comes with the same unlimited win multiplier in the Free Spins Bonus as BTG's Bonanza slot. Furthermore, the cascading symbols make it possible to create several consecutive wins on each spin.


At the right-hand side of the Diamond Mine slot game screen, you can use the tappable buttons to change your bet size to a value between 20p to £100.

There's also an icon that lets you read the rules and paytable, and another that turns the sound effects and music on and off.

Diamond Mine is a six-reel slot that uses MegaWays rather than paylines. The number of MegaWays changes with each spin due to the symbols landing in varying sizes, and can hit a maximum of 117,649.

The mine provides the central focus for the game, which makes the reels look as though they're buried deep underground. The background scenery consists of an arid desert with the occasional cactus and a blue summer sky.

You can win prizes by landing matching symbols like the pickaxe, the miner, the lantern, the diamond, the money bag, and the sticks of dynamite.

Wild Symbol:

The bundle of dynamite is the wild symbol in the Diamond Mine slot, and it can substitute for every symbol except the scatter.

Bonus Features:

Diamond Mine comes with a Mystery Symbol – the TNT barrel – which, when it lands anywhere in view, automatically turns into any symbol apart from the scatter.

The money bag acts as the scatter symbol, and you need at least four to get twelve free spins, but if you trigger the Free Spins Bonus with more than four scatters, you receive an extra five free games for each additional scatter symbol.

In the Free Spins Bonus, each winning combination pushes the win multiplier up by x1. There's no maximum multiplier, so the sky's the limit! Plus, you can collect a further five or ten free spins if another three or four scatters appear while the bonus is active.

The Diamond Mine slot also uses Cascading Symbols, which means that each win reaction removes the winning symbols from view and lets more symbols take their place to hopefully create another winning combination.
