What is WoFinator?

WoFinator is a free Wings of Fire dragon guesser. Think of any dragon from the series by Tui T. Sutherland — a dragonet of destiny or a one-scene minor character — answer a handful of yes-or-no questions, and WoFinator works out who you were thinking of. Unlike WoFle, which is one dragon a day, you can play WoFinator as often as you like.

How to play

1. Think of a Wings of Fire dragon. Don't type it anywhere.
2. Answer each question: Yes, Probably, Don't know, Probably not, or No.
3. Answer honestly — one wrong answer will not throw it off.
4. When it thinks it knows, it names your dragon. It gets three tries.
5. If it never gets there, tell it who you meant, and play again.

How it works

There is no AI here, and nothing is guessed at random. WoFinator holds a likelihood for all 300 dragons in the index at once, and every answer reweighs every dragon. The question it asks next is whichever one splits the remaining field most evenly — so it closes in fast, and the same answers always produce the same round. It runs on the same dragon profiles as WoFle, which means the work that makes one accurate makes the other accurate too.

Spoilers

WoFinator will not spoil a book you haven't reached. Set how far you've read in settings: it will never name a dragon from past that point, and it will treat any fact you haven't read yet — a death included — as something it simply doesn't know.

About

WoFinator is made by Wings Up Anthems, a fan project that writes original songs for the dragons of Wings of Fire. Every dragon it names links to their profile and, where one exists, their anthem.
