AO3dle

AO3dle is a character guessing game tool. A free browser guessing game that shows two characters and asks which one has more works on Archive of Our Own. Streaks, a personal best, game modes, a daily challenge and a global leaderboard give it replay value for fanfiction readers.

AO3dle is a browser game built around a single, deceptively simple question: which of these two characters has more fanfiction works on Archive of Our Own? Each round places two characters side by side with their fandom of origin, and the player picks the one they believe carries the larger work count. The reveal shows the numbers, and a correct pick extends the streak while a wrong one resets it. The roster pulls from a wide spread of source material. Pokemon and Mario characters sit next to Genshin Impact, Honkai, My Hero Academia, Undertale, My Little Pony, JoJo's Bizarre Adventure, Helltaker, Overwatch and Disney figures, so the matchups regularly cross genres and audience sizes. That cross fandom pairing is where the game gets its difficulty: knowing a franchise well does not guarantee you can rank its characters against a completely unrelated one. Players who follow fanfiction culture tend to reason from ship popularity and demographic size rather than raw screen time, which is roughly the intended skill. Around the core loop the site layers a streak counter, a personal best, selectable game modes, and a global leaderboard. A daily challenge gives returning players a fixed set to work through, and a live chat panel runs alongside the game where players post reactions, streaks and complaints about unlikely results. The chat is unmoderated in practice and the visible history includes slurs and spam, so it is not a space to leave open around younger players. AO3dle sits in the same family as ranking and comparison quizzes rather than as a writing tool, despite appearing in content generation listings. It is free to play, needs no account, and is aimed at fanfiction readers who want a short distraction. Accuracy is the main caveat: community comments report work counts that look stale or wrong, and some characters appear under the wrong fandom label, so treat the numbers as a trivia approximation rather than a live statistic.
