Nine Men's Morris is a classic two‑player strategy game. Each player has 9 pieces. Place pieces, form mills, and remove opponent pieces — win by reducing the opponent to 2 pieces or by blocking all moves.
Phase 1: Alternate placing pieces on empty points.
Phase 2: Slide pieces along lines to adjacent empty points.
Phase 3: With 3 pieces you may fly to any empty point.
Whenever you form a mill (3 in a row), immediately remove one opponent piece (prefer one that isn't in a mill).
