Check Your Chiidoku Puzzle Entries

Enter your own placement notes to flag duplicate subjects in a row, column, or colour region. This is a local consistency check, not a level solver.

Duplicates and incomplete notes

No duplicate subject appears in the complete entries you supplied.

An empty duplicate result only checks these supplied labels. It does not confirm an in-game board, a solution, a reward, or a character outcome.
