Bingo is a term used in North American Scrabble for a play in which a player puts seven tiles on the board in a single turn.
Mattel, the game's manufacturer outside North America, uses the term bonus to describe such a word.
Much advanced strategy revolves around maximizing one's chance of playing of a bingo: blank tiles are kept, poor letter combinations such as BVW, GKUUV, IIIUU, or LLNNN are broken up, and flexible letter combinations such as AEINST (a six-letter "stem" that anagrams with 24 letters—all but Q and Y—to form nearly 70 bingos) are aimed for until a bingo is formed.
This strategy is often at direct odds with that of placing high-value letters on premium squares.
The highest-scoring bingo ever played in an official Scrabble tournament was by Karl Khoshnaw, who got 392 points for CAZIQUES in a 1982 game in Manchester.
