About SeeHowMany

SeeHowMany is a daily guessing game about numbers. How tall is the Eiffel Tower? How fast is a cheetah? You get six questions, 25 seconds each (75 if you turn on More time), and a score out of 600. Everyone gets the same six, and a new set arrives at midnight where you are.

There's a World set, and local ones for Ireland, the UK and the USA. No sign-up, no ads.

How to play, scoring, playing on more than one device, leagues and more: see Help.

Where the facts come from

Each answer comes from a source we name under it: a statistics office, a space agency, a sport's rule book, a record keeper. Where no official page is open to us we use Wikipedia, and the fact line says so.

Every question is checked twice against its source before it goes in, the second time by a checker who can't see the first one's evidence. We use AI to help draft the questions and to do both checks, and every answer names its source so you can check it too. If a source gives two different figures for the same thing, any guess between them gets full marks.

SeeHowMany is in beta: it's new and we're still tuning it.

Numbers change. If you spot one that's wrong or out of date, email hello@seehowmany.com and we'll fix it.
