Diamond Mine UK Online Slot

In late 2016, Big Time Gaming caught the eye of many UK online slots players with their mining themed release, named Bonanza. It went on to win awards and dazzled players with its smart use of Big Time's then-brand-new ‘Megaways' system. Since then, Big Time has agreed to a deal to license the software behind that system to Blueprint Gaming, and they've put it to good use with another mining game. This slot is very, very similar to Bonanza in terms of presentation, execution and just about everything else. Had Blueprint not paid Big Time for the use of the system, we suspect they'd have been sued. It's probably helpful to think of Diamond Mine and Bonanza as two connected online slot games, even though different companies produced them!

If you haven't played online slots that use Big Time's incredible ‘Megaways' system before, you're in for a treat, but you have to get your head around how it works first! We'll assist you with that. You probably raised your eyebrow when we told you there are 117,649 ways to win in this slot, and wondered how such a thing was possible. The answer lies in the dynamic and variable way that Diamond Mine uses its layout. There are always six reels in play, but the number of rows changes from reel to reel. Not only that, but that number will also change from spin to spin! The symbols in Diamond Mine can come in different sizes, and so a row might have two large symbols on it on one spin, and seven smaller ones on the next. It could also be somewhere in between the two.

Packing so much action into the reels and rows means that almost the entire display area has to be given over to those reels, and everything has to be kept a little basic-looking so players stand a chance of seeing what’s going on. Because of that, there isn’t a lot to say about Diamond Mine’s graphics. They’re serviceable, but we wouldn’t go as far as calling them beautiful. A few cactus plants around the reels, coupled with a sand-and-sky background, is enough to tell us that the min we’re working in is somewhere out in the desert. That’s fine - that’s all we need to know. The reels are made of grey stone from within the mine, supported by a wooden frame which also serves as the mine’s entrance.

With so much complexity in the way that Diamond Mine is presented, Blueprint decided to keep things a little more basic when it comes to symbols. The good old-fashioned playing cards from 9 to A account for those of the least worth. Every other symbol you’ll see on the reels is taken from the theme, and many come straight out of a miner’s bag. You’ll see some tools, a mining lamp, a big shiny diamond (thereby giving the slot its name), and the miner himself, who’s looking very pleased with himself.

Here’s where things get a little more complicated. There are more symbols in Diamond Mine, but one of them can only appear after a win takes place due to one of the slot’s features, and that’s the scatter. We’ll come to that in a second. There’s also a wild, which is represented by dynamite. That will replace everything apart from the scatter, but don’t worry about that - the scatter can only appear when you’re already on a winning streak, so your wild symbols will replace anything in the base game.

Diamond Mine’s scatter is a bag of gold, but won’t appear on a standard spin of the reels. Instead, it will fall in from above thanks to one of the best innovations of the ‘Megaways’ system. There’s a whole additional row in this slot, positioned above the regular reels. Whenever you make a winning combination, the symbols involved in your win will explode (hence the wild being shaped like dynamite), clearing space for the extra row to deposit its goods into that space. They can make new wins when they fall in, and these new wins will also disappear. That’s why they’re called Cascading Symbols - they’ll keep falling in until there are no more wins to be made. The bags of gold can only enter the reels this way, so you need to find a good chain of wins to make it happen.

Diamond Mine Developer - Blueprint

Even before they did the deal with Big Time Gaming that allowed them to use ‘Megaways,' Blueprint Gaming was a developer who was going places. They're a UK online slots developer based in Newark, but have a German parent company. They've made their name creating licensed products, often based on popular movies or television shows, although even the England football team have become Blueprint customers, partnering with them to create the ‘Three Lions' slot.

We expect to see them make more and more use of ‘Megaways' as they get to grips with the system, and as they do so, they'll put their own spin on it and take it further away from the like-for-like match approach they took with Diamond Mine. In Primal Megaways, which is a more recent release, they're showing signs of doing so already. If they choose to use the system with any future licensed products, they may give Big Time cause to regret selling the license, as we suspect it will result in higher profile online slot games than Big Time are making themselves.

Diamond Mine Slot Bonus Features

There are two bonus features to play for in Diamond Mine, not inclusive of the Cascading Symbols feature we’ve described above. The first is a Mystery Symbol, which is a whole cluster of dynamite as opposed to the individual stick which serves as the wild. One or more of them may appear on any spin at random, exploding when the reels finish spinning. When they blow, they’ll be replaced by a set of matching symbols, potentially setting off a sequence of winning combinations.

The other bonus relies on you causing four scatter symbols to land on the reels. This takes time, because you need a good number of consecutive cascading wins to make it happen, but it’s well worth sticking around to trigger it. You’ll be rewarded with twelve free spins when you have enough bags of gold, although the feature can re-trigger when the feature is running if more bags of gold fall in. Each time a winning combination is found during free spins, the multiplier applied to the next win increases by one. There’s no upper limit to this, so if the wind is blowing your way you could easily reach a multiplier of 10x or more before the feature ends.

As we said at the start of the review, this is Bonanza in everything but name, but there are worse online slots to copy than Bonanza. Blueprint earn no points for originality by publishing Diamond Mine, but if you like one of the slots, you'll like the other. Megaways slots take a little getting used to, but once you have a proper understanding of the system, you may even prefer it to the more standard way of playing slots.
