The Rank Group plc is a gambling company based in the United Kingdom. Rank was involved in the cinema and motion picture industry until 2006, and continues to use the Gongman logo originally used by the Rank Organisation's film distribution subsidiary General Film Distributors. Its brands now include Mecca Bingo, and Grosvenor Casinos, the UK's largest casino operator.

Bingo is a game of probability in which players mark off numbers on cards as the numbers are drawn randomly by a caller, the winner being the first person to mark off all their numbers. Bingo, previously known in the UK as Housey-Housey, became increasingly popular across the UK following the Betting and Gaming Act 1960 with more purpose-built bingo halls opened every year until 2005. Since 2005, bingo halls have seen a marked decline in revenues and the closure of many halls. The number of bingo clubs in Britain has dropped from nearly 600 in 2005 to under 400 as of January 2014. These closures are blamed on high taxes, the smoking ban, and the rise in online gambling, amongst other things.
