The new format of the Customisation Spotlight is a “this-or-that” style voting system, where you will be shown two Neopets side-by-side. You will be able to vote for which one’s look you prefer, or (if in the monthly themed contest) which pet you think fits the theme better. Once your vote is cast, a new pairing will be shown to you, and you can vote again!
Once you vote on a pet, it will not be shown to you again in the same contest. That means you can only vote for a pet once, so think carefully before casting your vote!
