Social-betting start-up BetGame has been named the first winner of William Hill's accelerator programme scheme, launched last year in partnership with L Marks. BetGame, a Manchester-based start-up, is an app that lets two people place a bet on the result of a console or PC video game, such as football title FIFA. Gamers can bet against a friend or any other player. BetGame works by overlaying its app on mainstream console and PC games to monitor the outcome and determine the winner.
