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 variants variant for children five to seven years of age on one side and a version for older children aged seven to ten on the other. Two to four players can take part in a game. In the simpler version, young players connect letters with words on the game board. The words have been preprinted on the playing field and only have to be covered by the letter tiles until a complete word has been constructed. If the board is flipped, words must be constructed independently, as they are in adult Scrabble. This game is a cross between Othello and Scrabble
