AO3dle

AO3dle is a free web-based trivia game that tests players' knowledge of character popularity on Archive of Our Own (AO3) by guessing which of two characters has more fanfiction works.

What is AO3dle?

AO3dle is an online game that compares the number of fanfiction works for two randomly selected characters from AO3. Players see a pair of character images and names, along with their respective work counts (the left character's count is shown, the right is hidden), and must decide which character has more fanfics. The game runs entirely in the browser and is developed by an independent creator (no company or team is named on the site).

How does AO3dle work?

1. The game loads a random pair of characters from its database, displaying both images, names, and the work count for the left character.
2. The player clicks either the left or right character to indicate which they believe has more works.
3. If correct, the streak increases and a new pair appears. If wrong, the streak resets and the game ends in endless mode or the daily challenge is lost.
4. The data is sourced from AO3's tag system, though some user comments suggest occasional inaccuracies due to tag overlap.

FAQ

Is AO3dle free?

Yes, AO3dle is completely free to play. There are no paywalls, subscriptions, or in-game purchases.

Does AO3dle require a registration?

No. You can start playing immediately without signing up or logging in. The streak and best score are stored locally in your browser.

How accurate are the character work counts?

The counts are pulled from AO3's tag search, but the site's own chat shows users occasionally reporting mismatches (e.g., Glaceon appearing with 70k+ works when its actual tag has fewer). The game itself acknowledges this in comments from the developer (e.g., "Thank you for your feedback. The number of submissions has been corrected.").
