Board game for two people, played on a special board with
nine pieces. The board has three 'concentric' squares linked at the mid points
of their sides. Play is divided into three stages, but the object throughout the game is to
get three pieces in a line - called a mill. On forming a
mill, one of the opponent's pieces is removed from the board and the
player who reduces an opponent's remaining pieces to two wins the game.
The opening stage begins with an empty board. Each player has nine pieces which
are placed one at a time in turn on any vacant point on the board until
both have played all nine.
