Rarity calculations are similar to those used by many other rarity sites. If you're interested in the theory behind the rarity calculations, this article gives a very good overview.

Each NFT is ranked by:

• Assigning a score to each attribute based on the number of other NFTs with the same value for the attribute. The exact formula is:
  attribute score = number minted / number with same value
• Attributes with a value of "None" are scored based on the number of other NFTs that also do not have a value for the attribute, because sometimes not having a particular attribute could be rare!
• All attribute scores are summed to give a total score for the NFT.
• NFTs are ranked starting at rank 1 for the highest score (rarest) to lowest score (least rare).

Note: The rarity rankings for all ThetaZillas and PixZillas have been provided by the creators, so rankings will not change as more NFTs are minted. The PixZilla rankings supplied by the creators don't include customs in the numerical ranks (that is, the first non-custom is rank 1). On Theta Rarity all customs have rank 1, so the highest ranking non-custom is rank 2. All the PixZilla ranks displayed on this site will therefore be "out by one" when compared to the PixZilla rank in the attributes.

The method used here to calculate an NFT's rarity based on individual attributes, while good, does have some shortcomings:

• At lower rarity levels, where the bulk of the NFTs sit, NFTs can be very different in rank despite having similar scores.
• As the combination of attributes possessed by an NFT aren't considered, the algorithm cannot determine the uniqueness or rarity of the NFT as a whole. If a particular combination of attributes is considered particular rare and valuable, this may not be reflected in the rarity ranking.
