Each player starts with 12 tokens called cows.
Players alternately place cows on the board with your mouse.
Once all the cows have been placed on the board, cows may only be moved on the board to free, adjacent intersections, except when a player has only three cows left (then he may move to any free intersection).
The aim is to create rows of three called mills, either vertically, diagonally, or horizontally.
When a mill is achieved, the player may capture one of the opponent's cows by clicking on the cow.
A player cannot capture an opponent's mill if there are other cows on the board left to capture.
The game is over and a player loses when he has only two pieces, or has no moves left.
The best intersections are the corners of the middle rectangle. Often a winning situation is a double mill. This is where a player can move back and forth between two mills, making a mill and removing an opponent's piece on every turn.
