Slots game developers Nolimit City are building a fine reputation for producing action  packed, feature rich games and their latest offering, Fire In The Hole, is no exception. The company have experimented with some unusual settings and themes for slots games – such as in the recently released San Quentin xWays, where they took us to the yard of one of America’s most infamous prisons – but they find themselves back on familiar territory with Fire In The Hole, a good old-fashioned mining game.

While the theme may be traditional, the game-play is cutting edge, with a dizzying assortment of bonus features including the Collapsing Mine feature, Wild Mining, xBombs and the Lucky Wagon Spins bonus round.

Pros & Cons

  • Abundance of bonus features.
  • 60,000x max win.
  • Exciting, varied gameplay.
  • Unoriginal theme.
  • Can be confusing at first.
  • High volatility.

How to Play

Fire In The Hole is a six reel slot that starts with three rows and 486 Ways. Every time you complete a winning combination by matching three or more symbols from left to right, the Collapsing Mine feature causes the game board to expand with an extra row, up to a maximum of six rows and a whopping 46,656 Ways. This is a fresh and innovative take on the trend towards more and more paylines started by the popularity of Megaways games, and showcases how online slots are continuing to evolve. As the game board expands, all symbols in winning combinations are removed to be replaced by new symbols, allowing chains of wins to be formed.


Fire In The Hole’s reels are populated with colourful symbols that reinforce its mining theme. Playing card symbols from Nine to King are the game’s lowest paying symbols. You’ll find these symbols in all sorts of online slots games and they’re depicted here stamped onto wooden crates, which helps them gel with the rest of the game’s artwork. Symbols portraying a miner’s essential gear provide the game’s higher paying symbols. In ascending order of value, they are the Pickaxe, the Rope, the Boots, the Satchel and the Lantern.

The special xBomb Wild symbols are crates of dynamite. These Wild symbols don’t just substitute for all other symbols except Scatters, they also explode to expand the game board and clear out all surrounding symbols. Keep an eye out for the Gold Nugget scatter symbols. Landing three or more of these anywhere on the board will trigger the Lucky Wagon Spins bonus feature, where you can win up to 60,000x your stake.


Fire In The Hole has three main bonus features: xBomb Wilds, Wild Mining, and Lucky Wagon Spins.

Bonus Name Bonus Explanation
xBomb Wilds

xBomb wilds substitute for any other symbols to complete a combination. xBomb wilds explode to clear all surrounding symbols except bonus symbols and increase the multiplier for the next win by 1x.

Wild Mining

When three or more matching symbols land in a horizontal line but don’t form a win, the middle symbols of the line will be replaced with Wild Mining symbols and all symbols above the line are removed.

Lucky Wagon Spins

The Lucky Wagon Spins feature is triggered by landing 3 or more Bonus symbols.

  • Landing more Bonus symbols causes the feature to begin with more rows unlocked.
  • During the feature, a row of minecarts runs along the top and drops bonuses down onto the game board.
  • Bonuses include coins, multipliers and other symbols that unlock more of the board or increase your prize.
