Nine Mens Morris is a classic board game.

Each of the two players has nine pieces
which they put alternately on any free point of the game board.

The game proceeds in three phases:
1.Placing pieces on empty points.
2.Moving pieces to adjacent points.
3.Moving pieces to any empty point when a player has only three pieces left.

If a player gets three pieces in a line - a mill
he removes one of the opponent's pieces from the game board.

A player has lost if he has only two pieces left or
if he is not able to make a move with one of his pieces.
