Wassies.org Ranking Methodology

While it's always important to remember that 1 wassie = 1 wassie, some wassies are more disgusting and undesirable than others. As such, I've compiled a ranking of wassies, outcasts, and couches by order of the rarity of their revolting traits. Each trait (e.g. Sailor Hat) is counted amongst all wassies (e.g. 206 Sailor Hats), and then divided by the total number of wassies to get a rarity percentage (e.g. 206 Sailor Hats / 11094 wassies = 1.86%). The rarity score is simply 1 divided by the rarity percentage (e.g. 1/.0186 = 53.85). Once the rarity score is found for each trait of a wassie, all the trait rarity scores are added together for a total rarity score.

This is the same methodology used by rarity.tools. See the basis for this reasoning in a very well written article.

However, every NFT collection has its quirks, and wassies are no exception. They are basically made of quirks. Giant, smelly, balls of quirk. Anyway, I've taken the liberty to alter the "normal" way of ranking wassies and come up with yet-another-wassie-ranking based on the following...

Separation of NFT types

If one ranking list is good, then three is better, right?!? Each wassie type listed below has a mutually exclusive list. Rankings are independent of each type. There is a #1 couch, a #1 outcast, and a #1 wassie. Scores between groups cannot be compared because couches are not wassies are not outcasts.

  1. Couches - The 250 couches have their own set of traits. And, you know, they're couches, not wassies. They get their own rankings.
  2. Outcasts - The forgotten ones share a number of traits: Backgrounds, Beaks, Body Colour, Belly Colour, and Sigil. Rather than not give them points for any of these non-traits that normal wassies might have, they get their own rankings. Plus, they are outcasts, so it only makes sense to cast them out of the ranks of the regulars.
  3. Wassies - The smol tings. There are 15 "Special" wassies: 13 one-of-ones and 2 laser beam tings. The other 11079 are normal wassies that will die after 14 days and can be safely ignored and/or tossed in the wassie slicer.

The Colour Problem (binning)

Some traits have a lot of possible values. Namely, Body Colour and Belly Colour. All the normal wassies have a body or belly colour, but each colour is comparitively "rare" on its own. However, pretty much any colour is interchangeable with any other colour (with few exceptions like skeletons). In other words, if all colors are rare, then none are rare. One way to minimize the impace of common colors from making a wassie seem rarer than it should be is to group many of the colours together into a 'common' color, and assign rarity based on the grouping rather than the individual color. This is called "binning" for data nerds.

Aside from colour, a few other trait values have been binned due to their commonality and interchangeability. These bins are listed below:


  • Sigil - Every normal wassie has one of six sigils, however, the white ones kinda suck, so I grouped them all together into a Common sigil bin.
  • Eyes - The five most common eye types ("Wassie", "Dead", "Inconvenienced", "Small", "Almond") are grouped into a Common bin.
  • Background - There are three 'neutral' backgrounds (light, dark, neutral) which are all now "Common" backgrounds.
  • Body and Belly Colours - Here's where the real action happens. There are a massive list of colours each with 40-90 occurrences. These are all grouped into the Common bin. Another set of colours with fewer colours, and fewer total occurrences are grouped as Uncommon. The solid colors (Crystal, Ruby, Water, etc...) are grouped as Rare, and the Skeletons and Dissected are left unbinned because they are awesome (and have much lower occurrences than the other solid types).


Outcasts either have machign traits (beaks, backgrounds, etc...), or very distinct traits (clothes, wieldables). The only exception are eyes. Most outcast eyes are pretty awful, so they are binned. Some are fantastically rare and are left alone to get a phenomenally high score.


Nothing was done to alter the scoring of couches. If you have a couch, you're GMI.


More detailed explainations and examples are coming soon. Maybe.
