The Mill is a logic board game for two players. As playing pieces, 9 black and 9 white round pieces are usually used (in our program, the pieces are colored). The object of the game is to place three pieces of the same color in a row.
At the beginning, the playing field is empty and the players take turns to put their chips on any free space, so as to put three of their chips in one row. This continues until all available chips have been exposed. If it turns out to line up a row of three pieces (a mill), then the player takes any opponent's piece from the field. Next, the players take turns moving the pieces to the empty spaces along the lines, also trying to build a mill and pick up the opponent's pieces. Sometimes it is believed that if you manage to build 2 rows of three chips each, then 2 opponent's chips are taken, but this rule is absent in our programs. The mill can be built in one place several times, but the token is removed only for the first construction.
