Fire Gnomes Slot by Crazy Tooth Studio

The BIG BuildUp mechanic splits gameplay into two loops. Powder keg and coin symbols land on reels 1 and 4 during base spins, collecting on shelves beside the grid. When a feature activation symbol hits reels 2 or 3, everything releases at once - wilds, wild multipliers (2x through 5x), and silver or gold cash prizes all drop onto the reels.

The bonus gameboard works on a different principle. Two scatters open a board filled with credit values and five special symbols: retrigger, credit boost, row, column, and orthogonal. Gnomes throw multiplier kegs (2x-5x) across 5 spins. The orthogonal symbol spreads its multiplier in four directions, chaining prizes across multiple board positions from a single keg.
