A game built around clinical curiosity
Our cases are fictional teaching scenarios, not patient records. They simplify clinical presentations into a puzzle with an intended answer. The aim is to encourage recall, comparison, and discussion across healthcare specialties.
Daily cases and released archives are free to play. Selected public case reviews bring the clues, diagnosis, reasoning, and a reference together on a page you can read without an account.
How case content is prepared
Our current case-authoring policy requires research for the diagnosis and decisive clinical facts. It favors clinical guidelines, government and professional-society resources, reference texts, and peer-reviewed sources. Sources should support the claims made in the case, and the reference linked from a case gives readers a starting point for checking and further reading.
We use AI tools to assist with research, drafting, and translation. Under our current process, AI-assisted content remains a draft until a person reviews and approves it, and publication requires a separate human instruction. Automated checks help identify inconsistent facts, missing sources, translation gaps, and answer leakage; passing those checks is not publication approval.
This describes our editorial requirements. It does not certify clinical accuracy or establish that every case has been independently reviewed by a licensed specialist. Fictional details, simplified presentations, and errors can affect a case, so readers should check unfamiliar or disputed claims against trusted references.
What a case result means
A correct answer means you solved that puzzle with the information provided. It is not a validated assessment of clinical competence, a professional qualification, or a substitute for a curriculum, supervised training, or clinical judgment.
