How to Play Fire In The Hole 4
Fire In The Hole 4 features a 6×6 grid with 46,656 ways to win. Each spin begins with 3 active rows, and additional rows become active as collapses occur, up to a maximum of 6 rows. Winning combinations, xBomb® Wild explosions, and the Wild Mining feature can trigger collapses, removing symbols and allowing new ones to fall into place.
Players can also encounter xWays®, Infectious xWays®, and xSplit® symbols, which expand or multiply the symbols on the grid. During the main game, Wild Mining can activate when 3 to 6 matching symbols align horizontally or vertically without an existing win or active xBomb® Wild. Landing 3 or more Bonus symbols triggers Lucky Nugget Spins.
Fire In The Hole 4 Theme & Graphics
The game follows the dwarf into a jungle adventure driven by rumours of Golden Balls and an unexpected reunion with his younger brother. Its setting introduces a new territory while keeping the familiar dwarf-themed humour and mining-inspired elements. The gameplay centres on collapsing symbols, buried features, explosive Wilds, and the Lucky Nugget Spins bonus.
Fire In The Hole 4 Slot Features
- Collapsing Waterfall: Each spin starts with 3 active rows. Winning combinations, xBomb® Wild explosions, and Wild Mining can trigger collapses, activating additional rows up to 6. Winning symbols are paid and removed before the remaining symbols fall and new ones enter the grid.
- xBomb® Wild Multiplier: Substitutes for any symbol except Bonus symbols. When it explodes, it removes all non-Bonus symbols in its row and column and increases the win multiplier by +1 for the next collapse. After exploding, it transforms into an xBomb® Wild, xWays®, Infectious xWays®, or a regular paying symbol.
- xWays®: Transforms into a regular paying symbol covering 2 to 4 positions.
- Infectious xWays®: Transforms into a regular paying symbol covering 2 to 4 positions and infects all occurrences of the same symbol on the reels, turning them into size 2 to 4 as well. Multiple Infectious xWays® symbols do not affect one another.
- xSplit®: Splits symbols in its row and column, doubling those symbols. xSplit® symbols cannot be split and turn into regular paying symbols after activating. Dirt blocks affected by a split are removed during a collapse.
- Wild Mining: Triggers when 3 to 6 matching symbols align horizontally or vertically without a winning combination or active xBomb® Wild. The triggering symbols are removed and replaced with Wilds in the middle positions of the alignment.
- 3 matching symbols award 1 Wild.
- 4 matching symbols award 2 Wilds.
- 5 matching symbols award 3 Wilds.
- 6 matching symbols award 4 Wilds.
- Positions above the Wild Mining bar, except Bonus and Dirt Buried symbols, explode and trigger another collapse.
- Buried Features: Dirt symbols in the main game can contain xBomb® Wilds, xSplit®, or Bonus symbols. These features remain inactive until the dirt block is removed or affected by an xSplit® or xBomb® feature.
Fire In The Hole 4 Bonus Features
Lucky Nugget Spins Feature
- Landing 3 or more Bonus symbols triggers Lucky Nugget Spins.
- The feature starts with 3 spins and resets to 3 whenever a Nugget lands on the reel area.
- The bonus uses 4 active rows, Collector Chests at the bottom, and an Upgrade Reel on the right.
- Nuggets and Dwarfs move down one position after each spin until collected by the Collector Chests.
- All Nugget and Dwarf values are calculated as multipliers of the active bet.
- Each spin reveals Enhancers on the top row, which activate when a Nugget lands beneath them.
- The Upgrade Reel can reveal multipliers of ×2, ×3, ×5, ×10, ×25, or ×100. These multiply all Nugget and Dwarf values on their row when landing on an unlocked position.
- Upgrade Reel positions are sealed with 1 to 4 locks. Each triggering Bonus symbol or Dynamite removes one lock.
- The following Enhancers can appear:
- Nugget Values: Sets the value of the triggering Nugget.
- Multipliers: Multiplies the value of all Nuggets on the reel below the Enhancer.
- Dynamite: Adds its count to the triggering Nugget, then throws that number of Dynamites onto reel positions. Landing on a Nugget or Dwarf doubles its value, while landing on the Upgrade Reel removes a lock from a 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 and locks Nuggets and Dwarfs in their positions for the awarded number of Freeze spins.
