Players
two to ten
Boneyard
For two players a double six set is used. For three to five players a double nine set is used. For six to ten players, a double twelve set is used.
The Deal
Each player receives seven dominoes at the beginning of a round. Excess dominoes form the boneyard for the round.
The Play
The player holding the highest double sets it. From this first domino only the east and west sides are open. Each player in turn must play a domino on one of the open ends by matching a number on the domino to a number on the open end. If a player is unable to play, she must draw a domino from the boneyard until a playable domino is drawn. If the boneyard is empty she must pass. A round ends when a player goes domino or when all players have passed in succession.
Scoring
A player who goes domino scores the points remaining in all opponents' hands.
If a round ends because all players are blocked, each player scores the difference between the count in hand and the points remaining in higher count opponents' hands.
The game ends when one player reaches 250 points.
