Sanmill v1.0.4

A Mill Game which supports many rule variants.

Rules:

• A player who aligns three of his pieces on a board line has a mill and may remove his opponent's piece(s).
• Any player reduces to two pieces and has no option to form new mills and thus loses the game.
• A player can also lose with more than three pieces, if his opponent blocks them so that they cannot be moved.

Features:

• Support many rule variants, such as Nine Men's Morris and Twelve Men's Morris, "Fly" Rule or no "Fly" Rule
• Play against the AI, or play both sides
• Adjustable playing strength
• Highly configurable
• Color themes

走棋阶段动态调整深度
