Occam's Razor is a card game designed to teach health sciences students and clinicians about medical diagnoses. The instructions suggest four play variants, including basic set collection, competitive set matching, deduction, and solitaire play. 1. Be the first to deduce the hidden disease card. 2. Gin Rummy: collect the highest scoring hand of matching symptoms. 3. Solitaire: Match symptoms in order to clear all of your face-down piles. 4. Spoons: no medical knowledge needed.
