Grab your pickaxe, it’s time to dive deep into this mining-themed slot from the innovative studios of Just For The Win. Big Boom Riches is a 5-reel, 3-row and 20-payline slot that looks pretty basic at first glance but does contain some glints of gold when it comes to its bonus features and clever Rolling Reels mechanic. The action starts off above ground amongst the mountains but soon heads into the depths of the goldmine once the free spins bonus feature kicks in. Will you be able to dig deep enough to uncover the slot’s 5,000x your stake max potential? Read our full review to find out how to get started!

Big Boom Riches Bonus Features

We’re happy to report that Big Boom Riches lives up to its rather boastful name when it comes to the bonus features on offer. A Rolling Reels mechanic means that winning symbols disappear, with new ones dropping down to fill the gaps for multiple wins possible on each spin. 3 different types of wilds that play a key role in both the slot’s base game and free spins round, with any TNT Wilds exploding to create further cascades. The free spins bonus round features a nifty progressive multiplier that increases anytime an X-Wild hits the reels during the round to give your wins a further boost.

Rolling Reels Feature

When you land a win on a payline, the symbols involved disappear from the reels, and fresh ones will drop down to fill in the gaps. This is called the Rolling Reels feature and allows you to pick up multiple wins from a single paid spin of the reels. It will only stop once no more wins occur or no TNT Wilds or X-Wilds are present.


Big Boom Riches goes all-in when it comes to wilds with 3 different ones, a regular wild, an X-Wild and a TNT Wild, active during play. They all behave as you’d expect by substituting for paying symbols to give your spins some added potential. The additional bonus with TNT Wilds and X-Wilds is that they will detonate when they hit the reels and blow away any adjacent symbols too. This action will trigger the Rolling Reels feature for some additional win potential. TNT Wilds also award a cash prize of up to 5,000x your stake when 3 to 12 of them arrive on the reels as part of a Rolling Reels sequence.


A jolly-looking prospector with a lone golden tooth shows up as the scatter symbol in Big Boom Riches. He’ll award you with a payout of 2x, 20x, or 100x your bet plus 9 free spins when you land 3, 4, or 5 scatters respectively.

Free Spins

Once the free spins feature triggers, landing any further scatter symbols won’t pay out but will give you 1 extra spin for each one. You’ll also get a progressive win multiplier that starts at 1x and increases by an additional 1x each time an X-Wilds appears. Each individual win during the round is multiplied by the current multiplier total. Players from some locations might be able to buy the free spins round at the cost of 50x their bet; however, this is not available to UK players.

Big Boom Riches Jackpot

A 5,000x your bet potential is the top prize to dig for in Big Boom Riches because we can promise you that there’s no progressive jackpot hiding down the mine here.

RTP and Volatility

Big Boom Riches arrives as a highly volatile slot with an RTP of 96.06%. This stat is bang on the industry average for slot games and, coupled with its volatile nature, may mean you’ll need to toil away for a while before any larger wins appear.
