The object is to remove your opponent's pieces from the board. To do this you have to get three of your pieces in a row either horizontally or vertically. This is known as a MILL. To start you take it in turns to position the pieces on the board. If you create a mill at this stage you are allowed to remove a piece belonging to your opponent. Once all pieces have been placed on the board you move into the mid-game section.
In the mid-game you take it in turns to move a single piece one position along the lines of the board. If you create a mill you can remove an opponent's piece, unless that piece is part of a mill. A mill piece can be removed if there are no non-mill pieces left. To win the game remove all but two of the opponent's pieces or force your opponent into a position where they have no move.
