An arcade game (or coin-op) is a coin-operated entertainment machine, usually installed in public businesses, such as restaurants, bars, and particularly amusement arcades. Most arcade games are video games, pinball machines,electro-mechanical games, redemption games, and merchandisers (such as claw cranes).

The golden age of arcade video games lasted from the late 1970s to the mid-1990s. While arcade games were still relatively popular during the late 1990s, the entertainment medium saw a continuous decline in popularity in the Western hemisphere when home-based video game consoles made the transition from 2D graphics to 3D graphics.
