Scrabble is a word game that can be played by two to four players. The game involves placing tiles, each bearing a single letter, onto a game board divided into a 15x15 grid of squares. The tiles must form words that read left to right in rows or downward in columns, in crossword fashion, and are included in a standard dictionary or lexicon. Players earn points by constructing words with letter tiles and placing them on the board. Each letter has a different point value, and there are 100 letter tiles. The game ends when all the tiles have been drawn and one player uses their last letter, or when all possible plays have been made. The player with the highest score at the end of the game is the winner. Scrabble can be played casually or competitively, and there are official tournaments for those who want to play at a higher level.
