Brackmill Duel

Brackmill Duel modifies traditional nine men's morris by activating corner diagonals. The grid features three concentric rings connected by orthogonal and diagonal paths. Aligning three stones creates a mill, permitting the user to extract one opponent stone. Stones inside mills maintain immunity unless no alternative targets remain. Matches conclude when a participant drops below three stones or lacks available paths. PROCEDURAL PHASES Matches execute in three stages. During Placing, participants alternate depositing nine stones onto empty points. The Moving phase requires shifting stones to adjacent vacant intersections to manipulate alignments. If reduced to exactly three stones, the Flying phase begins, lifting adjacency restrictions and allowing traversal to any open point across the board. AI AND LOCAL MODES The application features a programmed opponent utilizing Gentle, Steady, and Sharp difficulty tiers. The highest tier calculates future maneuvers and unlocks upon defeating the intermediate tier. A shared-screen mode accommodates manual turn-passing on a single device, maintaining visibility for both participants of the Brackmill Duel.
