Hm, odd
It seems that some get more challenges that others offered and some different challenges than others catered by their device or options.
An annoying badge I saw them griping about on reddit that only affects those who get the option of 12 instead of 11, and the same for me is:
Easy on the Eyes
Earn this badge when you register a Kindle E‑reader device.
Obviously I doubt many will de-register and then re-register their devices, or buy a new device in the month of January just for this badge, which does not count toward earning the credit anyway since it's not a diamond badge .
