Big Boom Riches Slot RTP, Details & Wager Limits
Big Boom Riches is played on a 5 reel, 3 row, 20 payline machine. Winners are created by landing 3, 4 or 5 matching symbols or wilds from left to right in a payline, starting from the leftmost reel.
Slightly unusually for a paylines slot, Rolling Reels are active here. Land a winning combination and the successful symbols explode from the reels and new symbols drop into the vacated positions.
Reel Rolls also trigger whenever a TNT Wild lands with all symbols adjacent to the TNT Wild (apart from scatters and standard wilds) being removed from the grid. The Reel Rolls continue until no new winner is formed or no new TNT Wild or X Wild land.
Stakes in Big Boom Riches range from between 20p and £50 per spin. To adjust your stake, click on the coin above the spin button.
To access the paytable, click on the 3 dots then choose the gold star. Payout amounts are shown as cash value and are relative to your current stake level.
The Big Boom Riches RTP is 96.06% which is about average. The hit rate is just over 27% so on average, you’ll land a winner on just over a quarter of spins.
As you might expect for a slot with this theme, the action here is explosive as far as the variance is concerned. The Big Boom Riches slot game volatility is very high. The maximum win is 5,000 x your stake.
Theme – dig for Victory
The cartoon-style design in the Big Boom Riches slot game is simple but rather nicely done. You’ll see mountains in the background as well as a railroad and plenty of sticks of dynamite. Graphics is something slot provider Just for the Win always does well.
The wooden reels are made up of A to J royals and 4 higher-paying gemstone symbols. The best of the quartet is the pink gem which pays 15 x your stake if you land 5 in a line.
The game also comes with 3 different wilds – Standard Wild, TNT Wilds and X Wilds. These all replace everything apart from the scatter and pay 1, 3 or 15 x stake if you land 3, 4 or 5 in a line. The TNT and X Wilds can deliver special extras which we’ll look at below.
The grizzly old miner is the scatter symbol and that scatter symbol is also the most valuable one in the game. You’ll also hear a hillbilly-style backing track while you spin which is a good fit for the mining theme. It’s not the flashiest slot you’ll play but the blue-collar design works pretty well.
Here’s a useful list of the symbols used in the game and their potential winning returns:
| Symbol | Paylines |
|---|---|
 J | 3, 4, or 5 = 0.2, 0.5 or 1 x stake |
 Q | 3, 4, or 5 = 0.2, 0.5 or 1 x stake |
 K | 3, 4, or 5 = 0.2, 0.6 or 1.5 x stake |

 Purple Gemstone | 3, 4, or 5 = 0.4, 1 or 3 x stake |

 Orange Gemstone | 3, 4, or 5 = 0.8, 2.5 or 7.5 x stake |
 Pink Gemstone | 3, 4, or 5 = 1, 3 or 15 x stake |
 TNT Wild | 3, 4, or 5 = 1, 3 or 15 x stake and substitutes all symbols except scatter |
 Wild | 3, 4, or 5 = 1, 3 or 15 x stake and substitutes all symbols except scatter |

 Miner Scatter | 3, 4, or 5 = 2, 20 or 100 x stake plus 9 free spins |
 Miner Free Spins Scatter | 1 extra free spin for every one that lands |

The round starts with a 1 x multiplier active. Hope to see plenty of X Wilds in this round. Each time one appears, it increases the value of that multiplier by 1 x. This doesn’t reset following an unsuccessful spin either, it can increase throughout the feature.
Scatters don’t offer any payouts during this round. Each time one lands though, one extra free spin is added to your current total.
In some territories, including the UK, players will have the opportunity to buy the Free Spins round. This costs a fee of 50 x your stake.
