An amusement arcade or video arcade is a venue where people play arcade games such as video games, pinball machines, electro-mechanical games, redemption games, merchandisers (such as claw cranes), or coin-operated billiards or air hockey tables. In some countries, some types of arcades are also legally permitted to provide gambling machines such as slot machines or pachinko machines. Games are usually housed in cabinets. The term used for ancestors of these venues in the beginning of 20th century was penny arcades.
