Big Boom Riches

Grab your hard hats and get ready for a deep dive into a mine shaft full of potential cash prizes because Big Boom Riches is ready to be played and reward you with more nuggets than you ever experienced before. Our casino site is always on the lookout for the best online slot games, and therefore we keep a keen eye on monthly online casino games releases. What caught our eye here was the existence of 3 wild symbols and a bonus feature that awards players free spins. On top of that, there's cascading reels to give you win reactions that see you win far more. Let’s go digging for gold.

Big Boom Riches has a mining theme around the gold rush in the good ‘ol US of A, with a seriously rural looking miner digging through rural America in search of jewels. We've definitely seen sharper visuals when it comes to graphics, although the grainy look is probably what the iGaming studio was going for. Speaking of the iGaming studio, it goes by the name of Just For The Win and forms part of the Microgaming umbrella. They certainly seem to like themes that centre around gold, with Emerald Gold and Elvin Gold being 2 of their previous releases. However, neither has the cascading reels mechanic like Big Boom Riches. This element sees every win receive what is essentially a respin, and if that ‘respin' is a win, it happens again.

The volatility is on the higher side of all Just For The Win’s slots online, so you land fewer wins, but the values are higher, unlike medium volatility where more wins land, but they're worth less. You can win up to 5,000x your bet in Big Boom Riches, which isn't too bad when looking at other online slots, although you can find higher-paying slots here at PartyCasino. The maximum stake limit for the high rollers out there is £50, while the lowest wager you’ll be able to place is 20p. All the action can be enjoyed on mobile devices, so feel free to take the casino gaming action around with you.

Some slots online use the symbols to make a bit of a statement, sometimes to demonstrate how creative they've been. With Big Boom Riches, the studio wasn't too concerned as the symbols are really quite basic, which we can understand, given the theme. The lower paying icons are playing card royals J, Q, K and A, with A and K carrying the joint highest value. There’s then the medium paying ones which are four different colour gemstones, with the ruby being the highest paying for 3, 4 and 5 of a kind winning combos.

Together with the ruby, the three wild symbols carry the joint highest value for winning combinations. The wilds also act as all regular symbols in the slot to make up winning symbol combinations. Look out for the hillbilly miner who serves as the scatter.

The wilds, apart from substituting symbols, also have differing functions. For example, the TNT wild explode symbols around it. You can also collect TNT wilds during cascading wins sequences, and if you manage to collect 12 through a wins sequence, you'll win 5,000x your stake.

As mentioned right at the start of the review, there are free spins to be triggered. Landing 3, 4 or 5 scatter symbols on the same spin will award you with nine free spins. Players might think this is a bit stingy from the studio, but landing one or more scatters on free spins adds +1 extra spin. The X-Wild lands during free spins to add 1x multipliers that keep growing the more X-Wilds you land.

In most cases, online slot machines will have a free spins feature to serve as the added value. However, Big Boom Riches has been generous in adding the three wild symbols to increase the winning action in both regular play and bonus play. It might not be the prettiest of slots you’ve ever played, but Big Boom Riches has plenty of winnings to go around.
