Nolimit CityFire in the Hole 2

Fire in the Hole 2 is Nolimit City’s sequel to the mining classic Fire in the Hole. It keeps extreme volatility and a 96.07% theoretical RTP while expanding the collapsing-mine fantasy with Lucky Wagon Spins and updated xBomb chaos.

On demo.black you get the full HTML5 free demo with virtual credits — same bonus paths as the cash build, no registration or download.

Compared with the original, the sequel leans harder into wagon tiers that unlock rows and multipliers. Use the browser demo to feel how often the mine expands before any real-money session.

Base play is built around an expanding grid: wins and bombs can open new rows and stack pressure toward the free-spin feature. xBomb symbols clear spaces and can chain into bigger boards.

Lucky Wagon Spins are the headline bonus — wagons add multipliers and progression while the mine grows. Optional bonus buy (when enabled in the mirror) is useful only to preview the feature screen in demo, not to judge long-term RTP.

Lock one virtual bet and run 150–250 spins. Track how often wagons trigger versus dry stretches — that gap is the Extreme label in practice.

Open Full screen for longer mobile sessions. Treat advertised max-win figures as rare ceilings; the demo’s job is to show pacing and feature frequency before you play for cash.
