Donkey Kong is a 1981 arcade video game developed and published by Nintendo. As Mario, the player runs and jumps on platforms and climbs ladders to ascend a construction site and rescue Pauline from a giant gorilla, the titular Donkey Kong. It is the first game in the Donkey Kong series as well as Mario's first appearance in a video game.

An arcade video game takes player input from its controls, processes it through electrical or computerized components, and displays output to an electronic monitor or similar display. All arcade video games are coin-operated or accept other means of payment, housed in an arcade cabinet, and located in amusement arcades alongside other kinds of arcade games. Until the early 2000s, arcade video games were the largest and most technologically advanced segment of the video game industry.
