from Game Cabinet Review
Each player is a doctor practicing a specific type of medicine - acupuncture, drugs, blood letting, electric shocks - all the very latest techniques, all neatly color coded. Your hand of numbered cards may have some of your own color, and certainly some of other players' colors, and both low and high cards are useful as we shall see. In the manner of Carry On Doctor, the hapless victim patient is wheeled in before the arrayed quacks. Every patient is different, but your aim is to cure him (by having the largest combined total of cards in your color) without killing him (ditto, but exceeding the patient's specified limit). Your typical private patient is pretty weedy, so expires on a total higher than 14. You might play your own 8 card hoping to get close to the total, but your rivals will be only too pleased to play a 5 and a 3 to kill him off. The body goes into your mortuary (minus points) hopefully to be offset by cured patients (positive points). And that is it.
