Questions
Which rules are used?
Classic nine-stone Morris on 24 points, with flying at three stones and one capture per newly completed mill, even if two mills form together. An existing mill can be opened and closed again. Three repeated movement positions with the same player to move, or 100 movement turns without a capture, draw the game.
How strong is the AI?
Easy, Medium and Hard use bounded local heuristic search in a Web Worker. This is a practice opponent, not a solved or tournament-strength engine. No board or moves are sent to a server.
Can I play a remote opponent?
This page offers computer play and two players sharing one device. It does not offer remote multiplayer rooms.
