Scrabble is a word game in which two to four players score points by forming words from individual lettered tiles on a gameboard marked with a 15-by-15 grid. The words are formed across and down in crossword fashion and must appear in a standard dictionary. Specified reference works (e.g., the Official Club and Tournament Word List, the Official Scrabble Players Dictionary) provide a list of permissible words. The name Scrabble is a trademark of Hasbro, Inc. in the United States and Canada; elsewhere, it is trademarked by Mattel. The game is sold in 121 countries and there are 29 different language versions. Approximately 150 million sets have been sold worldwide, and sets are found in roughly one-third of American homes. The game is played by two to four players on a square board with a 15-by-15 grid of cells (individually known as 'squares'), each of which accommodates a single letter tile.
