About Fermi

How to play

Three estimation questions a day, such as how many Oreos are eaten in the U.S. each day. No searching: use gut instinct and napkin maths (there's a built-in calculator), and give one guess each.

You're scored on how far off you are, as a multiple of the real answer, and compared with everyone else who played.
