Winning Lines is a BBC1 quiz show from Celador, the people responsible for the quiz-show phenomenon Who Wants to be a Millionaire?. It is a number-based quiz show designed to wrap around the National Lottery. Originally hosted by Simon Mayo, its third season is hosted by Philip Scofield. Winning Lines is all about numbers and contains three rounds. In the studio are the Forty-niners, 49 contestants who have to be the fastest to answer questions correctly in order to eliminate their opponents and go through to the next round. The top prize is a round-the-world trip. Like the Millionaire quiz books, the Winning Lines quiz book is interative but even more so, with 15 complete games for number wizards.
