Order Alex Bellos's book now and get a limited-edition 'Matt verified' copy.


Thanks to Matt Scroggs and the Chalkdust folks for helping organise the volunteers and the maths.


Cheers to the Ri for letting us film in their building.


We have free Think Maths work sheets for any teachers who want to use the prisoner puzzle in their lessons.


CORRECTIONS

- We do know there is a limit I believe, but we don't know what it is.
- Let me know if you spot any other mistakes!
