Scrabble

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.
