Merrelus is played on a board by two players who take turns. The players start with three, six or nine different colored stones each. To start the game, the players place their stones on any of the available circles on the board.
When all stones are placed, the game enters the second part. Players now move their stones. A stone can be moved from one circle to another along the lines. Stones can never be placed or moved to a slot that is already occupied.
Whenever a player forms a mill (three stones in a row), he can take any opponent’s stone that doesn’t belong to a mill. If all of the opponent’s stoness are inside some mill then an exception is made and the player can take any stone.
The game is won by bringing the opponent to a position where they cannot move, or by reducing them to only two stones.
