Big Boom Riches - Head deep inside the dark mine

Big Boom Riches is an online slot developed by Microgaming's collaboration with Just For The Win. This game is one of the best creations between the 2 iGaming giants. Land rewarding winning combos on 20 different paylines, thanks to the classic-design gaming grid with 5 reels and 3 rows.

Just For The Win released Odin's Riches before Big Boom Riches, and this game was one of their most popular titles. Impressed with Odin's success, the developers decided to use the same bonuses and jackpot in Big Boom Riches that they used in Odin's Riches.

Big Boom Riches is an attractive choice with high game volatility and a 5,000x jackpot. The generous hit rate of 27.34% grants you a win on roughly every 4th spin, which is pretty impressive.

Theme & Design

Big Boom has great visuals and the theme is gold mining. You'll get a complete tour of the gem mine. The game starts with the gaming grid in the front, and you can see huge mountains and trees in the background. As you proceed with the game and trigger the special round, Big Boom Riches takes you deep inside the gold mine, where you can see dynamite crates and cart tracks.

The reels in Big Boom Riches are unique. Usually, reels in free video slots spin as if they are discs spinning around a rod. Interestingly, in Big Boom Riches, it feels as if the symbols are being dropped from a box and are later getting caught by the same box. This box looks as if it's made out of wooden planks and serves as the gaming grid as well.


You are going to see a huge variety of symbols in Big Boom Riches as the Rolling Reels bonus remains active during the gameplay. Card-based symbols from J to A denote the low-value symbols in the game, and the high-value ones are represented by shiny purple, pink, green, and orange gems. These gems are precious and hold the potential to give you payouts worth 3x to 5x.

A total of 3 different Wilds are there in the game, one regular Wild, an X-Wild, and a TNT Wild. All these special symbols substitute for the regular symbols, and the X-Wild & the TNT Wild trigger the Rolling Reels feature as well.

Big Boom Riches - How to Play

It's pretty simple to bet on Big Boom Riches. After launching the game, the first thing you should do is open the paytable and read about the different winning combos you can land.

Then select a bet amount to start your gambling session. You can set a min bet of €0.20 per spin and a maximum of €50 per spin in this release. Consider your gambling strategy and bankroll size before you set the bet amount, and keep modifying it as you go ahead.

The final step you'll take is to spin the reels by pressing the spin button. The giant button on the game screen's right side is the spin button. Click on it, and the symbols will drop from the grid to rearrange later in the same box.

You can use the auto-play feature in the game that lets you set a number of spins, and the grid starts spinning on its own. You can set between 10, 25, 50, and 100 automated spins.

The option to buy the Free Spins is placed on the left side. You can use the buy bonus feature if you feel like the Free Spins are taking a long time to trigger on their own.

Grid-blowing Bonus Features

Rolling Reels Feature

This bonus gets activated as you land a winning combo on the gaming grid. When the Booster triggers, the symbols constituting the winning combo are removed from the grid, and new symbols will drop.

This modifier lets you win multiple payouts from a single spin. This results in multiple cascades, and the winning chain comes to an end only when no wins occur or when there are no X-Wilds or TNT Wilds present on the grid.


Big Boom Riches is a pretty generous game from the perspective of special symbols. You get 3 different types of wild symbols, a regular Wild, an X-Wild, and a special TNT Wild. Just like usual Wilds, these symbols substitute for all the regular symbols and help in landing winning combos.

The X-Wilds and TNT Wilds come with added benefits. If you use them in landing payouts, these symbols detonate and blow away any symbols adjacent to them. This explosion works like a cascade and mixes up the gaming grid.

The TNT Wilds also give away instant cash prizes worth up to 5,000x when you land at least 3 of them together on the grid in a Rolling Reels sequence.


A greedy prospector with a golden tooth appears on the reels every once in a while and acts as the Scatter symbol. This prospector will give you instant payouts worth 2x, 20x, or 100x worth your bet, along with 9 free spins as you land 3, 4, or 5 Scatters together.

Free Spins

As the Free Spins round is in progress, any Scatter symbol you land on the grid will give you an additional Free Spin per Scatter. The bonus round also rewards you with a progressive Multiplier that begins at 1x and increases each time you land an X-Wild. Every individual win you land during the round gets multiplied with the current Multiplier value.
