The Fire in the Hole 3 slot comes with the usual bonus features from its predecessors as well as a few new extras. With Collapses, xBomb Wild Multiplier, xSplit, xHole, Wild Mining and Buried extras, there is the Lucky Wagon Spins, which has more Enhancers and bigger win potential.
Collapsing Mine
You’ll notice that each spin begins with 3 active rows, giving you up to 486 ways to win. When you land a winning combination, an extra row becomes active (up to 6 rows). New collapses are triggered by the following events:
- A winning combination
- xBomb Wild explosion
- Wild Mining feature trigger
- xHole feature trigger
When a collapse occurs, the winning symbols are removed from the reels with the remaining symbols falling downwards: this leaves empty symbol positions which are filled with new symbols dropping in from above. With each win, Enhancer Cell positions unlock (beginning from left to right).
xBomb Wild Multiplier
The detonator is the xBomb Wild symbol, which substitutes for all symbols bar the Wagon Coin Bonus. Removing adjacent symbols (except the Wagon Coin Bonus), the win multiplier is increased by its value for the next collapse. All xBomb Wilds explode before the next collapse, unless you trigger the Wild Mining feature.
Wild Mining
When 3 to 6 of the same kind of symbols align horizontally or vertically and no winning combinations land, active xHole or active xBomb Wild, the Wild Mining feature will be activated.
The triggering symbols are removed from play and create xBomb Wilds in the middle positions of the alignment. 3, 4, 5 or 6 symbols will award 1, 2, 3 or 4 Wilds.
Then, all symbol positions above the bar (except Wagon Coin Bonus and Ice Buried symbols) explode and trigger a new collapse. Ice Buried symbols are revealed and become active for more ways to win.
Buried Features
Ice Buried symbols in the base game can contain an xBomb Wild, xSplit, Wni Multiplier, xHole, Wagon Coin Bonus or Max Win symbol. They are inactive until the ice block they are trapped inside is exploded by an xBomb Wild.
Symbols inside Ice blocks are also revealed when split by the xSplit symbol (except the Win Multiplier). Also, empty Ice Blocks and Ice Blocks with Win Multiplier values affected by a split feature are removed if a collapse occurs. Win Multiplier values range from 2x up to 100x.
Finally, a Max Win symbol will appear as a 2x2 symbol in an ice block. Once all the ice is cleared from the symbol, the max win of 70,000 x bet will be awarded and won.
xHole

The xHole feature is triggered when the xHole symbol appears. With paying symbols drawn from the reels, they are scattered to random positions with split symbols which are 1-3 symbols in size. The xHole leaves an empty space in its position, which, in turn, triggers a collapse. If you land multiple xHole symbols, the symbol size increases several times.
xSplit
As with other Nolimit City slots, an xSplit symbol splits all other symbols on its reel, doubling those symbols. Wagon Coin Bonus, xSplit, and xHole symbols cannot be split, though.
Once all xSplit symbols become active, they transform into 1 of the regular, paying symbols. Finally, Ice blocks affected by the xSplit symbol are removed if there is a collapse.
Gamble
If you manage to win 5 times your total bet or higher in the base game, the Gamble feature is an option. If taken, you gamble your win for a chance to win your way into the Lucky Wagon Spins feature.
Lucky Wagon Spins

As with other Fire in the Hole slots, there is a Lucky Wagon Spins feature. It is triggered by landing 3, 4 or 5 Wagon Coin Bonus symbols: this gives you 2, 3 or 4 rows open, respectively.
Beginning with 3 spins, the number of spins resets to 3 every time a coin lands in the play area. Coins contain a bet multiplier value.
If you manage to trigger the feature with 6 Wagon Coin Bonus symbols, you’ll play with a Persistent Dwarf on the first spin and 4 rows of the reel area active. Once in, the top row reveals Enhancers on each spin. An Enhancer is activated when a Coin lands on the reel below the Enhancer. Below, you’ll find details on the Enhancers appearing on the top row:
- Coin: Contains a bet multiplier prize
- Multiplier: Multiplies the value of all Coins, Persistent Dwarf and the coin value of Persistent Dynamite on the reel below the Enhancer.
- Dynamite: Adds the Dynamite count as bet value to the triggering coin. It then throws as many Dynamites as its count on reel positions. It removes Ice Blocks, doubles Coin values, activates Chests, reveals symbols on Ice, doubles the Coin value on Dynamite/Persistent Dynamite and doubles the Coin value if landing on Persistent Dwarf.
- Persistent Dynamite: On each spin, it drops several Dynamites equal to its count on the reel positions.
- Persistent Dwarf: Collects all values in the reel area at its triggering position on each spin.
- Evil Dwarf: Triggers a Golden Spin, which reactivates all the Coins on the reel area. Coins will trigger their respective Enhancers, boosting their existing values.
- xHole: Triggers 3 Frozen Wagon Spins and transforms itself into a 1x Coin. After the 3 Frozen Wagon Spins, Lucky Wagon Spins are resumed, and the spin left count is reset to 3.
- Frozen Wagon Spins: The top Enhancer row will only contain Coins. All the existing Coins in the reel area will collect the Coin values from the Enhancers and add them to their existing values.
- Collect Chests: The bottom row Collect Chest is activated by Dynamites. When activated, it collects the values in the real area for the corresponding column above for every spin. If the real area is full, normal Coins are removed with their values added to the bottom Coin of their respective reels.
