Players use the included tweezers to pick up the different ailment parts. But in this edition, they place them into the holes on Cavity Sam the way they're shown on the Operation card. The timer counts down as players hurry to insert the parts correctly. If they're successful, they keep the card and add up the points at the end of the game. If the timer goes off, all of the pieces pop! Contents: Game unit, 20 ailment pieces, 21 Operation cards, tweezers and instructions.
