How it works

The immortal snail thought experiment, played for real on your phone.

1. Meet your snail

Terry appears 4 km from you and starts crawling, about 12 meters an hour. Stay put and you have around 14 days.

2. Walk, salt or travel

Every walk buys you time. Salt stops Terry for an hour. Leave town for three days and Terry books a flight.

3. Terry finds you

Eventually. You get a death certificate and a place in the hall of fame. There's no second snail.

Terry keeps in touch

Polite, patient and completely sure of the ending.
