Big Boom Riches Features

Big Boom Riches utilises the Rolling Reels™ feature that sees winning symbols removed from the reels, allowing for new ones to fall down from the top of the screen into the empty spaces. 

This explosive slot really comes into its own when special wild symbols land on the reels, causing adjacent symbols to explode.

Wild symbols

As mentioned, this rootin' tootin' new online slot is all about the wild symbol, this game doesn't boast just one type of wild symbol, not even two... But three special wilds

These are your standard wild that substitutes for all symbols, a TNT wild that explodes, removing all regular adjacent symbols. In addition to this TNT wild symbols are collected in a barrel meter at the top of the game reels, seeing players potentially win cash prizes when 3 or more land. Finally, we have an x-wild that multiplies player winnings during the free spins bonus.

TNT wild payouts

If players land 3 or more TNT wilds during base gameplay then they'll be awarded a cash prize, these payouts are as follows:

Free Spins

If players land 3 or more prospector scatter symbols anywhere on the reels then they'll trigger 9 free spins.

The free spins bonus will begin with a multiplier of 1x, and every time an x-wild symbol lands on the reels this multiplier increases by +1. Every individual win in Big Boom Riches is multiplied by the current multiplier.

If a scatter symbol lands anywhere on the reels during this free spins bonus then players will receive an additional free spin.

Big Boom Riches Review

Big Boom Riches is a 5-reel, 20 payline Wild West-themed slot developed by Just For The Win that boasts 3 different wild symbols, including TNT wilds that can make for truly EXPLOSIVE gameplay. In addition to this, there's a hugely lucrative free spins bonus featuring progressive win multipliers that can net players huge cash prizes.


Who doesn't love a good old-fashioned mining-themed slot? This game features clean cartoon visuals that depict the Appalachian Mountains during the height of the gold-rush era. A mine-cart track snakes through the mountains and trees, leading to a deep underground mine full of untold riches (which you'll get to see if you trigger the game's free spins).

In terms of symbols, low paying ones are your standard J, Q, K and A whilst high paying ones are purple, green, orange and ruby gemstones. The special symbols are different versions of the word WILD and a heavily-bearded, gold-toothed old prospector features as the scatter symbol.

Unsurprisingly, the music you'll hear throughout is traditional Appalachian bluegrass... So if you enjoy the sound of a banjo then you're in luck! There are also some delightful voice clips that play every so often which will definitely put a smile on your face. 


This game is delightfully simple, land winning combinations, hope for TNT wilds and clear as many symbols from the grid as possible in order to enjoy consecutive cascades. 

The slot itself is played on a square in the middle of the game screen (which is perhaps unnecessarily small if we were to really poke holes), all of the associated buttons (game paytable and menu, autospin, stake selection and spin) are found stacked vertically to the right of the game grid.

Win Potential

Big Boom Riches is a high volatility slot with an RTP of 96.04% and a maximum win potential of 5,000x the player's stake. Whilst the maximum win doesn't blow us away quite like the TNT wilds, it's fair to suggest that big wins can be achieved with a bit of patience, especially during the free spins feature. 

Our Verdict

The moment we realised that this game featured exploding symbols that take out adjacent ones around it, that was it, we were hooked! Big Boom Riches offers players a satisfying, yet chaotic experience that leads to big wins. 

Throw in this slot's brilliant selection of special wild symbols and a lucrative free spins bonus and you've got yourself a pretty great game!
