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"
Scrabble "deluxe" sets still do. Both games are made by Winning Moves and feature smaller, plastic tiles that are held in place on the board with little plastic posts. The standard version features exactly the same 100 tiles as regular "Scrabble". The Tile Lock Super Scrabble features the same 200 tiles that are in Super Scrabble. Editions are available for travelers who may wish to play in a conveyance such as a train or plane, or to pause a game in progress and resume later. Many versions thus include methods to keep letters from moving, such as pegboards, recessed tile holders
