If you think this could be the slot game for you, carry on reading our Big Boom Riches review for all the information you need to know about this game.

How to Play

Spinning the reels of Big Boom Riches is easy. Players can click on the casino chop to set their bet per spin which can vary from as little as 20p to £50. Hit the gold arrow spin button to send the reels tumbling.

To create winning combinations in this game, players must land three or more matching symbols on the reels, starting from reel one, and from left to right.

The symbols on the reels of this game are:

  • A
  • J
  • Q
  • K
  • Orange gemstone
  • Green gemstone
  • Purple gemstone
  • Pink gemstone
  • WILD
  • X WILD


In the base game, the wilds and the pink gemstone symbol are the highest paying symbols on the reels. They will award players 15x their stake for five on the reels. With the bonus features, there is the chance to win up to 5000x your total stake.

Special features

There are two big special features in the Big Boom Riches slot game including the TNT Wilds feature and the free spins bonus round.

Players will notice that there are three wild symbols on the reels of Big Boom Riches. These act as your standard wild symbols and will replace other symbols on the reels to help form new winning combinations and award big cash prizes. The most lucrative, however, of the wild symbols is the TNT wilds as these will also award an instant cash prize when three or more land on the reels. Players can potentially win up to 5,000x their stake with the TNT wilds feature:

  • 3 TNT Wilds – 1x
  • 4 TNT Wilds – 3x
  • 5 TNT Wilds – 7.5x
  • 6 TNT Wilds – 15x
  • 7 TNT Wilds – 30x
  • 8 TNT Wilds – 75x
  • 9 TNT Wilds – 150x
  • 10 TNT Wilds – 300x
  • 11 TNT Wilds – 1,000x
  • 12 TNT Wilds – 5,000x

Players can trigger the free spins round by landing three or more miner scatter symbols on the reels. Before you are awarded your nine free spins, you will also receive an instant pay out:

  • Three scatter symbols – 2x
  • Four scatter symbols – 20x
  • Five scatter symbols – 100x

When you begin your free spins, there will be a 1x multiplier in play and this will increase by one each time the X WILD symbol lands on the reels. It will continue throughout the entire feature and you do not have to worry about it resetting after a non-winning spin. For every additional scatter symbol you land on the reels as you spin, you will be awarded another free spin.

Graphics and Sounds

Big Boom Riches is a mining themed slot game and has the high-quality graphics that we have come to expect from Microgaming. While the theme is not the most unique, the cartoon style graphics look fantastic and will take players to the dry and dusty mining landscape with some mountains, forest trees a rail track and dynamite sticks in the background. The reels are bordered in wood and the low value symbols are your standard playing card symbols A, J, Q and K in a variety of bright colours. The higher value symbols on the reels are an array of different coloured and shaped gemstones. A country music and hillbilly soundtrack plays in the background as you spin which works perfectly with the theme of this game.


Big Boom Riches is a fantastic slot game from Microgaming and you can instantly see the contribution from Just For The Win as the cartoon mining graphics look phenomenal. This game is not the most complex but players will enjoy its simplicity to spin. While there are not lots of bonus features, the two in play are very entertaining and will help players to take home wins of up to 5000x their stake. The TNT wilds and the free spins with increasing multiplier make this a game that you will definitely not want to miss out on playing and you could potentially mine a massive cash prize.
