Fire In The Hole 4 the upcoming slot by Nolimit City is set to go live on the 17th of November, 2026!

Each spin begins with 3 active rows and for each collapse an additional row becomes active up till 6 rows. A new collapse can be triggered by the following events: • A winning combination. • xBomb® Wild explosion. • Wild Mining feature triggered. Winning symbols are paid out and removed before triggering next collapse, which will make all symbols fall downwards leaving empty position for new symbols to drop in from above.

An xBomb® Wild symbol substitutes for any symbol except Bonus symbols. Each exploding xBomb Wild removes all symbols in its row and column (except Bonus symbols) and increases the win multiplier by +1 for the next collapse. After exploding, the xBomb® transforms into an xBomb® Wild, xWays®, Infectious xWays® or a normal paying symbol. All xBomb® Wilds explode before the next collapse, except during the Wild Mining feature or if revealed by another xBomb®.

xWays® and Infectious xWays® can be revealed from an xBomb® Wild symbol. xWays®: Transforms into a normal paying symbol of size 2-4. Infectious xWays®:Transforms into a normal paying symbol of size 2-4. It infects all occurrences of that symbol on the reels, turning them into size 2-4 as well. If more than one Infectious xWays®, they will not affect each other.

An xSplit® symbol splits symbols on its row and column, doubling those symbols. xSplit® symbols cannot be split. Once all xSplit® symbols have activated, they turn into regular paying symbols. Dirt blocks affected by a split feature are removed if there is a collapse. If Split is revealed from a Dirt symbol, it triggers only on the next avalanche.

Wild Mining will be triggered in main game when 3, 4, 5, or 6 of the same kind of symbols align horizontally or vertically and there are no winning combinations or active xBomb® Wild. The triggering symbols will be removed creating Wild symbols in the middle positions of the alignment: • 3 symbols award 1 Wild. • 4 symbols award 2 Wilds. • 5 symbols award 3 Wilds. • 6 symbols award 4 Wilds. All positions above the bar, except for Bonus and Dirt Buried symbols, will explode and trigger a new collapse. Dirt Buried symbols will be revealed and become active with the collapse.

Dirt symbols in main game may contain an xBomb® Wild, xSplit® or Bonus symbols. Feature symbols buried in dirt are inactive until the dirt block they are contained in is removed or hit by an xSplit® or xBomb® feature.

3 or more Bonus symbols trigger Lucky Nugget Spins. 4 active rows with Collector Chests at the bottom, and an Upgrade Reel on the right. The feature starts with 3 spins and will reset to 3 spins every time a Nugget lands on the reel area. All Nugget and Dwarf values are valued as times the active bet. Each spin reveals Enhancers on the top row, which activate when a Nugget lands beneath them. Nuggets and Dwarfs move down one position each spin until they are collected by the Collector Chests on the bottom row. • Upgrade Reel: The rightmost reel may contain random multipliers of x2, x3, x5, x10, x25, or x100 and multiply all Nugget and Dwarf values on their row when landing on an unlocked position. Each position is sealed with 1, 2, 3, and 4 locks and is activated once all locks on the position are removed. One lock is removed by each triggering Bonus symbol or Dynamite during Lucky Nugget Spins. Below enhancers may appear on the top row: • Nugget values: Sets the value of the Nugget. Multipliers: Multiplies the value of all Nuggets on the reel below the enhancer. • Dynamite: Adds the Dynamite count to the triggering Nugget. It then throws as many Dynamites as its count on reel positions. If it lands on Nugget or Dwarf it will double its value. If it lands on Upgrade Reel it will remove a lock from locked position. • Dwarf: Transforms the triggering Nugget into a Dwarf and collects all values in the reel area. • Freeze Cell: - Adds its count to the triggering Nugget. - Nuggets and Dwarfs on the reel area will lock on its positions for the duration of number of Freeze spins awarded. • Evil Dwarf: Removes the triggering Nugget and randomly multiplies the Collector Chest positions by x1 to x5.

Any xWays symbols that appear will reveal the same symbol, and if the symbol revealed is already visible on the reels, each in view will be ‘infected’ and will expand as if they are xWays, producing additional ways to win.

xWays® unlocks unprecedented win potential. Usually seen in a fixed Ways game, any xWays symbols that land reveals a stack of the same symbol, increasing the ways available to win, and when working alongside some of the other mechanics available in this series, such as xNudge or xSplit, can pave the way for some huge wins.

An xBomb Wild symbol substitutes any symbol except for the Bonus symbols. An exploding xBomb Wild removes adjacent symbols except for Bonus symbols and will increase the win multiplier by one for the next collapse. All xBomb Wilds will explode before the next collapse, except when the Wild Mining feature is triggered. An xBomb Wild will explode when there is a win, no matter if it’s a part of the winning combination or not. It will explode and trigger a new collapse if there isn’t a win, and wild Mining feature is not triggered.

Any xSplit® symbol in view will split all symbols to the left of it into two, increasing the ways to win. After this, the xSplit symbols will turn into wilds. Any xSplit symbols in view to the right of a Scatter symbol will turn the Scatter into a Super Scatter symbol.
