Facebook has teamed up with Gamesys to launch a version of online Bingo for Facebook users in the UK.
Users will be able to wager real money on Facebook, as the company opens its doors to gambling for the first time.
Gamesys, an independent gaming company, launched the version of online Bingo for Facebook users in Britain who are at least 18, and which the company said will pay winners real money. Gamesys also announced plans to offer virtual slots gambling on Facebook.
Facebook confirmed that it is partnering with Gamesys to allow gambling on its service.
"Real-money gaming is a popular and well-regulated activity in the UK and we are allowing a partner to offer their games to adult users on the Facebook platform in a safe and controlled manner," Facebook said in a statement.
Facebook spokeswoman Linda Griffin said there are no current plans to offer gambling in any other countries or with any other partners besides Gamesys. She declined to disclose what portion of the revenue Facebook would take from the gambling on the Gamesys games, but acknowledged that there was a revenue sharing agreement between Facebook and Gamesys.
Facebook takes a 30 per cent share of revenue for transactions on non-gambling games on its service, such as when users purchase virtual tractors and seeds in Zynga Inc's popular Farmville game.
Facebook, which makes the majority of its money from online advertising, has seen its revenue growth slow sharply during the past year. In the second quarter, Facebook reported revenue growth of 32 per cent, down sharply from the more than 100 per cent growth it delivered at the same time last year.
