The first player to use all his tiles wins the game, generally indicated by calling out
"domino" as the last piece is played from the hand. Once the winning piece
is placed on the skeleton, the game is over and all the players must expose their remaining
pieces to be counted in the scoring. No further plays can be made by any of the players.
It is possible for the game to reach a dead end, where all play is blocked and no tiles may
be played. This outcome is called a
jam
or a jammed game.
In this case, the end of the game is determined when the
boneyard
is empty and all players pass
consecutively (i.e., none of the players may make a legal play). To determine the
winner, all tiles held by players must be exposed and counted. The player with the least number
of pips
on the dominoes still held is declared the winner. When playing teams, the players on
the same team must have their hands combined to determine the team total and the team with the
fewest pips is declared the winner.
