Cain's Jawbone
Check your solution
Paste the printed page numbers in the order you believe the book should be read — the first page of the story first, the last page last. The check tells you only whether the whole order is right. It does not say which pages are wrong.
0 of 100 numbers
How this works
The correct order is not stored on this page. Only a one-way fingerprint of it is (a salted PBKDF2-SHA-256 hash). Your list is fingerprinted the same way in your own browser and the two fingerprints are compared. Nothing you type is sent anywhere.
Separators don't matter; anything that isn't a digit is ignored. The list must contain each number from 1 to 100 exactly once. The check takes a moment on purpose.
