The 400 Concepts questions come straight from the MillSong iOS design. Losing a piece is framed as part of the plan, never a scold, and the computer opponent scales from Gentle to Sharp. A hint appears only after a first try.
A game played around the world
Nine Men’s Morris — also called mill or morabaraba — has been played across the world for a very long time, on boards carved into stone, wood, and clay. We honour that shared tradition; the game belongs to everyone who plays it.
Each board's report card
How long is a game, does it usually end with a winner, and is it fair to whoever places first? The engine played each board against itself 1,000 times, choosing moves at random, and counted, using the same rules as the board: a long stretch without a capture, or a position that keeps coming back, is a draw. Random play is not how people play, so these numbers describe the rules, not players.
1,000 random-play games each. Placing a man, moving one, and the capture after a mill count as moves. White goes first on every board.
