A grid of pictures appears: type each character's name under their picture. Aliases and nicknames are accepted, as well as one small typo on names longer than 6 letters.
Available modes
10, 30 or 50 random characters — a random grid, for a quick game.
All characters — the full challenge: the whole database at once.
By area — every character who first appeared in a given arc (Alabasta, Wano…).
Difficulties
Easy — only the best-known characters. Hard — every character. The difficulty is locked during a game.
Only characters who have already appeared at your progress in the anime (chosen at the top of the page) are shown: nothing gets spoiled.
Give up
The Give up button reveals the names of the characters you didn't find.
