Operation is a battery-operated game of physical skill that tests players' hand-eye coordination and fine motor skills. The game's prototype was invented in 1964 by John Spinello, a University of Illinois industrial design student at the time, who sold his rights to the game to renowned toy designer Marvin Glass for a sum of US$500 and the promise of a job upon graduation. Initially produced by Milton Bradley in 1965, Operation is currently made by Hasbro, with an estimated franchise worth of US$40 million. The game is a variant on the old-fashioned electrified wire loop game popular at funfairs. It consists of an "operating table", lithographed with a comic likeness of a patient with a large red lightbulb for his nose. This could be a reference to classic cartoons, where ill characters' noses turn red. In the surface are a number of openings, which reveal cavities filled with fictional and humorously named ailments made of plastic. The general gameplay requires players to remove these plastic ailments with a pair of tweezers without touching the edge of the cavity opening.
Gameplay
Operation includes two sets of cards: The Specialist cards are dealt out evenly amongst the players at the beginning of the game. In the U.S and Australian version, players take turns picking Doctor cards, which offer a cash payment for removing each particular ailment, using a pair of tweezers connected with wire to the board. Successfully removing the ailment is rewarded according to the dollar amount shown on the card. However, if the tweezers touch the metal edge of the opening during the attempt, a buzzer sounds, Sam's nose lights up red, and the player loses the turn. The player holding the Specialist card for that piece then has a try, getting double the fee if he or she succeeds. Since there will be times when the player drawing a certain Doctor card also holds the matching Specialist card, that player can purposely botch the first attempt in order to attempt a second try for double value. The winner is the player who holds the most money after all the ailments are extracted. Subsequent later games removed the money and cards, and the winner of these editions is the player who removes the most ailments. The game can be difficult, due to the shapes of the plastic ailments and the fact the openings are barely larger than the pieces themselves.

"Brain Freeze" was added in 2004 when Milton Bradley allowed fans a chance to vote on a new piece to be added to the original game during the previous year, during the "What's Ailing Sam?" promotion. Voters were given three choices and could make their selection via the company's official website or by phone for a chance to win a $5,000 shopping spree. The winning piece beat out tennis elbow and growling stomach.
