Released in arcades in 1981, Donkey Kong , was not only Nintendo's first real smash hit but also introduced Mario and Donkey Kong. The game follows Mario as he tries to save Pauline from the clutches of the titular ape before time runs out.
Gameplay involves navigating through four industrial-themed levels, dodging obstacles like barrels, fireballs, and spring-weights, while trying to rescue Pauline within the time limit. Mario can find a hammer to destroy these obstacles for a limited time and collect additional points by finding Pauline's hat, purse, and umbrella. The game also features simplistic cut scenes that advance the story.
