Fire in the Hole 2: complete overview of the Nolimit City game

Nolimit City is a Swedish studio founded in 2013 that has built a solid reputation by going against the grain of classic publishers.

Where most developers focus on mainstream themes and classic mechanics, this studio has chosen a sharper editorial line: extreme volatility, innovative game systems and an artistic direction that leaves no one indifferent.

Its flagship titles (Book of Shadows, Mental and Mental 2, Tombstone RIP…) all share high reward potential and features that go beyond the usual boundaries of slot machines.

Fire in the Hole 2 continues in this vein with a mining theme carried through to the finest detail. The design, animations and soundtrack deliver total immersion — not forgetting the symbols (lantern, leather bag, cards, miner's boots and shovels). This casino game has been refined in every detail to take us on an underground journey.

Please note: it features an RTP of 96.07%, very high volatility, an evolving 6x6 grid and a maximum win potential of up to 65,000x your bet.

How to play Fire in the Hole 2?

Fire in the Hole 2's gameplay is based on a Ways system rather than fixed paylines: combinations form whenever identical symbols appear on adjacent reels, from left to right, across the entire grid (up to 46,656 ways to win simultaneously).

In addition to the classic symbols mentioned above, there are also bonus symbols (the gold coin) that trigger the Lucky Wagon Spins, as well as a Wild symbol that substitutes for all other symbols, explodes adjacent tiles and increases its multiplier.

Please note: if combinations form without triggering rewards, they are removed to generate a Wild symbol that explodes the entire grid (except bonus or Wild symbols).

There is also an xSplit symbol that divides the symbols on the row (maximum 8), and neutral earth symbols or those carrying an inactive bonus until the block is removed or divided by xSplit.

That covers the basics. Let's now look at the title's specific features.

Bonuses and special features of Fire in the Hole 2

The most important mechanic in the title concerns the 3 bottom rows, which remain locked until a winning combination or Wild explosion is triggered.

In each round, the grid offers 6 reels across 3 rows: the 3 bottom rows only unlock under certain conditions (Collapsing Mine system) and return to their original state at the end of each winning combination.

If you land 3 gold coins, you activate the Lucky Wagon Spins, which unlock the game's full potential. This mode is triggered by landing 3, 4 or 5 Scatter symbols on the reels (the more you land, the more active rows you open) and awards 3 free spins with a counter that resets each time a coin lands in the play zone.

During the Lucky Wagon Spins, the top row displays enhancers that activate as soon as a coin lands on the reel directly below.

Here is how they work:

• Coin values assign a bet-multiple value to the triggering coin;
• Multipliers apply to all coins already placed on the same reel;
• Dynamite fires a number of charges equal to its counter onto random grid positions, and can remove earth, double a coin's value or activate a chest in the bottom row;
• Beer reactivates between 0 and 5 coins already placed on the grid, causing them to trigger their own enhancers again on the next spin;
• The dwarf collects all values present in the play zone in a single action, at the position of the triggering coin;
• Bottom chests collect all values present on their reel on every spin.

Fire in the Hole 2 also introduces upgrades (purple crystals). When they appear on the 7th column (exclusive to this mode), they transform the behaviour of the corresponding enhancers. Coin values and multipliers remain active beyond the triggering spin and automatically reactivate on the next one. Dynamite, beer and the dwarf, meanwhile, become persistent functions, active on every spin without requiring a new triggering coin.

The mode ends either when the counter reaches zero with no new coin, or when the grid is entirely covered.

Fire in the Hole 2 vs other Nolimit City games

Looking at this summary table, Fire in the Hole 2 emerges as a slot well suited to players who want to access the studio's signature mechanics without facing the highest volatility levels in the provider's catalogue.

In addition, the title features fewer mechanics than some others (Mental 2, among others), which allows it to attract a wider range of player profiles, including beginners. The theme is also more mainstream than that of Mental, which is primarily aimed at fans of horror atmospheres.

Both beginner and veteran players find enough clarity to navigate the features with ease, while still benefiting from genuine win potential. It is this balance that makes it one of the most played slots in the Nolimit City range on casinos listed by TnBet.
