Trailhead Challenge in Dev. Edition

Trying to access Developer Edition to take Trailhead Challenges and get error messages upon login; however, if I go to the Sandbox from my SF login, works perfectly.   Is Sandbox different than Dev. Edition?

Yes, sandbox is different from Dev edition and trailhead challenges cannot be verified in sandboxes, but only in the dev edition.

Hi Deann,
 Yes a sanbox environment is different than Developer box. Sandbox is generally a full copy of your production environment whereas developer edition may or may not have all the data.  Hopefully this answers your question :)
