Who am I?

Who am I? is a guessing game built around famous names. Each question gives three clues and four possible players, and the job is to work out who is being described. Every player comes from the site's learning section, so newer fans who have read those pages will have a head start, while seasoned fans should find it a pleasant warm-up. It is a handy way of putting a story to the names commentators mention every Sunday, and it rewards a bit of detective work as much as memory.

The format is quick. There are 8 questions and the whole thing takes about four minutes. Read the clues, tap the name you think fits, read the note that follows, then move on to the next one. Nothing is saved to an account, so it is fine to have a guess, learn from the answer and come back later for another go.

For anyone who gets the bug for the game's great players, there is a proper place of pilgrimage. The Pro Football Hall of Fame in Canton, Ohio, opened its doors on 7 September 1963, and it has been honouring the sport's biggest figures ever since.
