How the Game Plays

Dwarf Mine takes you deep underground where a determined dwarven engineer operates a massive hydraulic digging machine. The base game starts on a 5x4 grid with 1,024 ways to win, but the layout is dynamic. Whenever a Bonus symbol (a drill) lands on the reels, the grid expands downwards by one row, increasing the number of ways to win. Winning combinations are formed by landing three or more matching symbols on adjacent reels starting from the leftmost side. The visual style is industrial and gritty yet polished, featuring pickaxes, helmets, and lanterns alongside lower-paying card suits.

Free Spins Explained

This slot features two different paths to free games. Landing three Bonus symbols in a single spin triggers the standard Free Spins mode, awarding 10 spins played on a fully expanded 5x7 grid with the maximum 16,807 ways to win. Alternatively, you can trigger Collection Free Spins by gathering five crystals of the same color (Red, Blue, Yellow, or Green) during base game expansions. These award 5 spins on the expanded 5x7 grid, but with a significant boost: the reels are populated with "Super High Paying" versions of the corresponding crystal, offering much higher win potential than the standard symbols.

Expanding Reels Feature Explained

The core mechanic revolves around the Bonus drills. Each drill that appears on the first, third, or fifth reels triggers an expansion. A single drill adds one row, two drills add two rows, and three drills trigger the bonus. These extra rows are the only places where collectible crystals can appear, making the expansion necessary to progress toward the lucrative Collection Free Spins.
