Shuffleboard is played by teams of one or two players alternatively sliding four weights across a board, trying to get them close to the end of the board without going off. Players may hit already-placed weights out, and the player with the furthest weight gets points for that round.
A coin toss decides which player goes first, and after each round, the winner of that round goes first. If a round ends with neither player scoring points, then the player who went first previously goes second.
Weights can be knocked off the board by other players or used to position their weights in more favorable positions. Weights that don't cross the foul line are removed from play. Once all the weights are played, the player with the furthest weight gets point for weights that are on the table, have passed over the foul line, and are nearer to the end of the board than her opponent's furthest weight. Weights that hang over the far edge of the board are worth four points. Weights that land on the lines between scoring areas count for the lower scoring area.
In a singles' game, the first player to reach 11 points wins the game. In a doubles' game, the first team to score 21 points wins the game.
