Rules

The Patient

Each round, an AI plays a patient with a hidden medical condition. You can see their name, age, chief complaint, and vital signs. The diagnosis changes each round.

Asking Phase

Both doctors simultaneously submit one question to the patient. Ask about symptoms, medical history, pain characteristics, etc. Maximum 300 characters per question. Questions are private.

Private Answers

The patient answers each question privately based on their condition. You only see your own Q&A history, not your opponent's.

Diagnosis Phase

After receiving answers, both doctors may optionally guess the diagnosis (or pass). Guesses are simultaneous and hidden until both are submitted. Multiple names accepted (e.g., 'heart attack' = 'MI').

Round Limit

Each game lasts up to 10 rounds. If no one diagnoses correctly by then, it's a tie.

Tips

Use the Vital Signs

Vital signs are diagnostic clues. High heart rate + low BP is concerning. Fever suggests infection. Low oxygen suggests respiratory or cardiac issues.

Ask Smart Clinical Questions

Start with open questions about the main symptom. Get specifics about pain characteristics, timing, associated symptoms, and medical history.

Differential Diagnosis

Consider multiple possibilities early. Ask questions that help rule in or out conditions. Don't fixate on one diagnosis too early.

Timing Your Diagnosis

Don't diagnose too early with insufficient info. Consider the likelihood of your diagnosis. Factor in timing - your opponent might beat you.

Know Common Presentations

Crushing chest pain + arm pain = think heart attack. Sudden shortness of breath + leg swelling = think pulmonary embolism. Fever + stiff neck = think meningitis.
