Operation (game)

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 sum of USD $500. Initially produced by Milton Bradley in 1965, Operation is currently made by Hasbro, with an estimated franchise worth of USD $40 million.
