Game starts when the player with the highest double bone place it on the table.This bone starts the line of play, a series of tiles in which adjacent bones touch with matching, i.e. equal, values. The players alternately extend the line of play with one tile at one of its two ends.If some of the players is missing matching number for some of the two ends of the row that players who cannot play must draw tiles from the "stock" until they find one which can be played. When there is no more bones in the "stock" the player has to press "Pass" so the opponent can make his move. The game ends when one player wins by playing their last bone, or when the game is blocked because neither player can play. The winner's score is the total remaining pip count of the loser's hand. The winner of a blocked game is the player who has a lower pip count, and the score of the game is the difference of the pip counts.
