Classic version
Donkey Kong Jr. starts at the bottom of the screen, where he is immediately bombarded by Nitpickers and Snapjaws. After climbing a pair of vines to the second floor, a piece of fruit can be found, which can be dropped on enemies below for bonus points. After avoiding more Snapjaws, Donkey Kong Jr. must jump to the swinging key above, which he can use to unlock part of his father's cage. He will drop down, repeating the process. Once four keys are delivered, Donkey Kong is free, awarding a big bonus to the player. Along the way, Donkey Kong Jr. can also grab hold of vines above, which help in avoiding the ground-bound Snapjaws.

Modern version
The version in the Game and Watch Gallery series of games had similar controls, although the enemies were different, including Goombas, Nipper Plants, Bullet Bills, and Spinies. The stage also alters its appearance each time the player successfully releases Donkey Kong: The game starts with a Jungle ground-level setting. Afterwards, it will switch to the treetops during sunset. Finally, the stage becomes a clouded area at night.

Super Smash Bros. series
In the Super Smash Bros. series, Mr. Game & Watch has a move where he swings a key in a near-identical fashion to Donkey Kong Jr..

Trivia

 * When the player plays the Modern version of Donkey Kong Jr. in Star Mode, all Goombas are replaced with Spinies, regardless of the score.
