Scrabble
End of game

The game ends when either:

At the end of the game, each player's score is reduced by the sum of the values of their unplayed tiles; if a player plays out, the sum of all other players' unplayed tiles is added to that player's score. This rule differs slightly in most tournaments; a player who plays out adds twice this sum, and the opponent's score is unchanged.
