The most popular word game in the world was designed by Alfred Butts in 1931. The game is designed for 2, 3 or 4 people. In general terms the game consists in withdrawing tiles with letters and arranging words of them on a special board, every next word must use at least one letter that is already on the board. The words arranged on the board remind a crossword as new words cross with the ones that have already been created or extend the existing ones by adding other letters.
