About Shrinkle

Shrinkle is a reasoning gym for DSM-5-TR differential diagnosis. Read a vignette, type a diagnosis, and get progressively more specific hints after wrong guesses — up to five total — before the correct answer and a DSM-grounded teaching panel are revealed.

Content disclaimer

Shrinkle is an educational tool for practising DSM-5-TR differential reasoning. Clinically valid diagnoses appear, including severe presentations (suicidality, psychosis, trauma responses). Shrinkle is not a diagnostic aid for real people.

How to play

Read each case carefully, then type your diagnosis into the input. The typeahead lists matching disorders. Submit your guess to see feedback. Wrong guesses reveal an additional hint, up to four hints after the initial vignette. Win or lose, every case ends with the same DSM-grounded teaching panel.
