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. Official 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, Scrabble 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.Checkout scrabble helper with board for more info.
The game is played by two to four players on a square (or nearly square) board with a 15-by-15 grid of cells (individually known as “squares”), each of which accommodates a single letter tile. In official club and tournament games, play is always between two players (or, occasionally, between two teams each of which collaborates on a single rack).
The board is marked with “premium” squares, which multiply the number of points awarded: eight dark red “triple-word” squares, 17 pink “double-word” squares, of which one, the center square (H8), is marked with a star or other symbol; 12 dark blue “triple-letter” squares, and 24 light blue “double-letter” squares. In 2008, Hasbro changed the colors of the premium squares to orange for TW, red for DW, blue for DL, and green for TL. The original premium square color scheme is still the preferred scheme for Scrabble boards used in tournaments.
In an English-language set the game contains 100 tiles, 98 of which are marked with a letter and a point value ranging from 1 to 10. The number of points of each lettered tile is based on the letter’s frequency in standard English writing; commonly used letters such as E or O are worth one point, while less common letters score higher, with Q and Z each worth 10 points. The game also has two blank tiles that are unmarked and carry no point value. The blank tiles can be used as substitutes for any letter; once laid on the board, however, the choice is fixed. Other language sets use different letter set distributions with different point values.
