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 Milton Bradley for a money of USD $500 and the promise of a job upon graduation. Initially produced by Milton Bradley in 1965, Operation is currently owned by Hasbro, with an estimated franchise worth of USD $40 million.

The game is a variant on the classic electrified wire loop game is popular at the fun fairs around the United States. It consists of an "operating table", lithographed with a comic likeness of a patient (nicknamed "Cavity Sam") with a red lightbulb for his nose. 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 not touching the edge of the cavity opening.

How to Play[]

Operation includes two sets of cards: The Specialist cards are dealt out evenly amongst the players at the beginning of the game.

In the North American 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 (thereby closing a circuit), 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 the players succeeds. Since there will be times when the player drawing a certain Doctor card also holds the matching Specialist card, that player can purposely screw up the first attempt in order to attempt a second try for double value. The game can be difficult, due to the shapes of the plastic ailments and the fact the openings are not quite larger than the pieces for the players.

If a player fails to take a piece not touching the side, or drops it while going through the obstacle course, they must move to the back of the line, and it's the next person's turn. Each piece is worth a specific amount of points, and whichever team has earned the highest score when time expires wins.
