Big Boom Riches

Delve underground to discover the treasure below the surface with Big Boom Riches, the online slot from Just for the Win released in September 2021. With a mining theme, you'll have to put in some effort to release the loot, but there's plenty waiting to be won in the dimly lit chamber. In fact, if you can collect the top prize, you'll receive a very tidy x5000.

Regular players will have seen many mining-themed slots before. Almost every developer has at least one mining title in their catalogue, but there's a surprising range of styles. Some slots machines revisit the Frontier and western towns, where you'll use dynamite to blow up an old mineshaft, such as Dynamite Digger. Others, like Mining Fever from Rabcat, take a fantasy approach with mythical dwarves featuring on the reels. Here in Big Boom Riches, it's simple: no dwarves or magical creatures, just gameplay set in an amber-lit chamber with plenty of precious jewels in plain sight.  

The game board is modest compared to many others, sitting squarely in the middle of the screen. The grid is 5x3 and contains 20 fixed paylines, fairly standard for this style of game. The min bet is just 0.20, making it very accessible for low rollers. This can be increased to the max bet of 50.00, a relatively low sum for those who want to max out chasing big money. A high volatility will help; you won't get lots of small prizes rolling in regularly, but if you can work in the mine for a while, you'll have a better chance of a bigger win.

The start of the game makes it clear that you're hanging out with American gold miners, complete with missing tooth, big beard and a friendly southern drawl. This is accompanied by a banjo soundtrack, giving you a real impression of taking a step back in time. The game setting itself is very atmospheric, with a dingy cavern, a swinging lantern and an orange light glowing in the distance. You'll really get a sense that you're buried a long distance below the surface, surrounded by imposing layers of rock.  

But, despite the low light, you can see well enough to play and you'll find the reels loaded up with some simple symbols. The low pays are the royals, while the premium symbols are made up of various gemstones. Match five of the top value jewel, and you'll receive a payout of x15.  

Every time you land a win, the matching symbols will vanish from the board, and new symbols will fall down from above, making new lines and potentially creating more matches. The board will be checked for any more wins, and if there are any, the process repeats again. Your turn will only finish when there are no more matches visible. This is known as the Rolling Reels function.

There are no fewer than three wilds on the reels, and they have an essential function in this game.  

There's a standard wild that does the usual, substituting for regular symbols to help you make more matches across the paylines.  

There is also the X-Wild and the TNT Wild; these can fulfil the purpose of a standard wild but do a little bit more.  

TNT Wilds appear during the Rolling Reels feature, and if you see more than three, you'll receive a cash prize. This could be anything up to x5000 for a maximum of 12 wilds.  

The X-wild appears during the free spins round, which you'll unlock by landing three or more scatters. Every time an X-Wild lands during free spins, the multiplier increases by +1.

Big Boom Riches from Just for the Win is a great mining themed slot. There probably isn’t anything here that you

haven't played before, but there's plenty to keep you entertained, and you could pick up some great prizes along the way!
