You have had a mild headache, you have searched it, and the internet has given you four months to live. That is the whole game. A symptom is read out, everyone plays the worst possible diagnosis from their hand, and the judge picks whichever one would ruin someone’s week most convincingly. A Thrilly party card game.
What is actually in the box
- Three hundred diagnosis cards against one hundred symptoms — the pairing space is where the jokes come from
- Plays the way your table already knows: read a prompt, submit an answer, rotate the judge
- Written to land hardest with nurses, med students and people who have been professional patients
- Travels well — two decks and a rules card, no board or pieces to lose
How a round goes
- One player reads the symptom card aloud and judges this round.
- Everybody else submits a diagnosis face down from their hand.
- The judge reads them all out, badly, and picks the one that does the most damage.
- Winner keeps the symptom card as a point. The judge role moves one seat left.
Who it suits, and who it does not
Buy it for
Healthcare friend groups, anyone who has ever diagnosed themselves at 2am, and tables that already enjoy the fill-in-the-blank format and want a deck with a specific world rather than general rudeness.
Skip it if
Family rooms — our reviewers are blunt that this one is not family friendly — and groups who want the humour gentle. A few cards are mean about patients rather than about doctors, and that lands differently depending on who is holding it.
The honest bit
This was our first deck and it is still the one that gets bought three at a time, usually by somebody who works nights and wants to inflict it on a staff room. The comparison reviewers reach for is Cards Against Humanity, which is fair on structure — the difference is that every card here lives in one world, so the jokes build on each other instead of resetting each round.

yes, yes, yes....
Hilarious- Fun for the entire adult family. We're a medical family, where Dad is a doctor and mom is a nurse.... we laughed for hours playing this game with the adult children who have heard the medical jargon and stories for all our lives.

Hilarious
If you are in healthcare, get this game and play with your other healthcare friends. Not family friendly! Definitely an adult game

hilarious for the right group
This game is hilarious, especially with healthcare worker friends or people who have spent way too much time as “professional patients.” The humor lands best if your group can laugh at medical anxiety, weird symptoms, and dramatic self-diagnosing. It was easy to pick up and made for a fun party game without needing a lot of setup. Definitely one I’d bring out again with the right crowd.

This Thrilly party card game, measured against the rest of the shelf
Diagnosthis is a card game about symptoms and bad medicine, played by a table of players who are all pretending to know things. It is not a board game: there are no figures, no tiles, no accessories to collect later, nothing collectible in the box at all, and no mobile tool to install. The deck is the apparatus. You read a set of symptoms, the room makes an educated guess, somebody is confidently wrong, and the action moves on before anyone can check a rulebook. The family shelf has gentler options; the box where you slap a sticky hand and take a sip is next door.
Everything factual above — player count, round length, the edition on the lid and the latest price — is based on the partner shop listing from our last check. Prices get revised and a popular edition gets restocked without notice, so the result on the shop page is the one to trust. The information here is ours only in the sense that we have personally played the thing. Delivery and tracking show up on your own order page, and the diagnosis is shared with nobody qualified.
