The 20th-century gold craze has served as an inspiration for many works of art. It has a special place in pop culture and has infiltrated the slot industry as well. No matter how corny it sounds, it’s a goldmine for developers. Digging for gold while blowing up reels with TNT has always been fun, and Microgaming has brought the gold mining theme back into the limelight with Big Boom Riches.

As the name obviously suggests, this is a mining-themed slot with exploding features. The Big Boom Riches slot uses 3 special Wilds and has tons of TNT that can make it rain gold nuggets down on you.

Available for free or real money in most new casino sites, you should test your luck on it and possibly blow the lid off this goldmine.

Big Boom Riches was developed by Microgaming’s long-time associates JustForTheWin. In visual terms, the slot looks perfect. There’s not a lot going on in the center – the reels are in a wooden frame with the background showing a hill and a mine entrance. All the controls are set on the right side for easy access. The slot has a cartoonish appearance and that good ol’ Texan appeal heightened by the soundtrack and sound effects.

The three Wilds and pink gem pay the most – 15x your stake for 5 of a kind. Scatter payouts are handsome too, just like TNT wilds. At least 3 of these will deliver an x1 win, but 12 pay a Multiplier of over 5,000x your bet.

Overall, this is a classic Microgaming slot in terms of layout and design that should sit well with most players.

The slot may be set in the days of gold fever, but it’s certainly modern in terms of features. It was developed on the HTML5 platform, making it available on a wide range of Android and iOS devices with no need to download any slot app.

Set your bet, and you can hit the Spin button to get the reels rollin’. Your options are between $0.20 and $50, suitable enough for all kinds of players. When you’re ready, you can start the action with the Spin button or use the Autoplay feature if you want to skip hitting the Space button all the time.

Rolling Reels take center stage in the base game. Just like Cascading Reels, whenever you score a win, the winning symbols will be blown off the reels, giving way to new ones. This means that you can score new winning combinations with each Rolling Reel, and these can continue infinitely.

Look out for the TNT Wilds. The Big Boom Riches slot has 3 of these, all playing their usual role. However, the TNT and X Wilds can also trigger special features that’ll come in handy for big wins. Land 3 TNT Wilds on the same spin, and you’ll land a 1x reward. You can land up to 12 of these Wilds on a single spin, paying the jackpot of over 5,000x your bet.

Three or more miner Scatter symbols will give you entry to the Free Bonus Spins Round. The Scatters will also pay a prize – 3 will double your payout, 4 pay 20x, while 5 pay 100x your stake. The Bonus Round starts with 9 free spins with an x1 multiplier active.

This is where the X Wilds come into play. Whenever one appears on the reels, the Multiplier value goes up by +1. You won’t see it resetting on losing spins, which boosts the slot’s winning potential in this round.

Landing a Scatter gives you an extra spin, with no caps on the number of free games.

The Big Boom Riches RTP is set to 96.06%. That’s common for a highly volatile Microgaming slot that can pay wins up to over 5,000x your bet.

Big Boom Riches is a Bonanza-like classic that brings the gold mining theme back where it belongs. It’s a slot with 3 Wilds and a slew of special features that can deliver instant wins in succession.

Play it for free or real money on your PC or mobile phone at the best online casinos and enjoy blowing up the reels hoping for a gold nugget.
