Scrabble have been sold worldwide and roughly one-third of American and half of British homes have a Scrabble set. There are around 4,000 Scrabble clubs around the world. The game is played by two to four players on a square board with a 15×15 grid of cells (individually known as "squares"), each of which accommodates a single letter tile. In official club and tournament games, play is 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"
Super Scrabble players find games with more players cramped. With its larger board, "Super Scrabble" is ideally suited for three- and four-player games. Indeed, its scoring sheets do not have enough lines to keep score for most two-player games. "Super Scrabble" has exactly twice as many tiles as "Scrabble", but the distribution of letters is not simply the original distribution doubled. The distribution is: The and indicate modifications from double the original distribution, with indicating more than double the original distribution, and indicating fewer. Note, for example, that there are more than twice as many S's (ten, whereas standard "Scrabble" has four).
