Features Fire In The Hole by Nolimit City is a mining-themed slot built on a 6-reel format with a starting 6x3 grid and 64 ways to win, expanding to 6x6 with up to 46,656 ways. The game uses a high-volatility model, with an RTP of 94.11% and a bet range from 0.2 to 50. Players can use the demo version to play for free and practice before playing for real money.
The base game centres on the Collapsing Mine feature, where winning symbols are removed and new icons fall into place for consecutive cascades. If a spin has no win but forms three, four or five matching symbols horizontally, the Wild Mining feature can add up to three wild symbols. The xBomb mechanic also appears as an explosive modifier, clearing adjacent symbols and increasing the multiplier for the next collapse.
Bonus play comes from Lucky Wagon Spins, which is triggered by landing three, four or five bonus symbols. The feature starts with three spins and resets whenever a new coin lands in the active area, while a moving train row reveals enhancers such as coin values, multipliers, dynamites, bags, chests and the dwarf modifier. The maximum payout is capped at 60,000 times the base bet.
