Donkey Kong Jr.

After its initial release in arcades, the game was ported to a variety of home consoles, including the Famicom/Nintendo Entertainment System (for which the game was released as a launch title in Japan). The game's title is written as Donkey Kong Junior in the North American arcade version and various conversions to non-Nintendo systems. The game was principally designed by Shigeru Miyamoto and his co-worker, Nintendo chief engineer Gunpei Yokoi. Miyamoto also created the graphics for the game along with Yoshio Sakamoto. A sequel, Donkey Kong 3, and a spin-off game, Donkey Kong Jr. Math, were released in 1983.

• Illustration — Donkey Kong Jr. trying to rescue his father from the cage next to Mario Like its predecessor, Donkey Kong Jr. is a platform game. There are a total of four stages, each with a unique theme. DK Jr. can run left and right, jump, and grab vines/chains/ropes to climb higher on the screen. He can slide down vines, or climb faster by holding two. Enemies include "Snapjaws", which resemble bear traps with eyes; bird-like creatures called "Nitpickers", some of which can attack by dropping eggs; and "Sparks" which roam across the wiring in one of Mario's hideouts. DK Jr. can jump over these enemies while on platforms, switch from one vine/chain/rope to another to dodge them, or knock down pieces of fruit that will destroy every enemy they touch before falling off the bottom of the screen. To pass the first three stages, DK Jr. must reach the key hanging next to his father's cage, whereupon Mario flees while pushing the cage off the screen. In the fourth stage, DK Jr. must push six keys into locks on the topmost platform to free Donkey Kong. After a brief cutscene, the player is taken back to the first stage at an increased difficulty. A bonus timer runs throughout each stage, and any points remaining on it are added to the player's score upon completion. DK Jr. loses a life when he touches any enemy or projectile, falls too great a distance, falls into water or off the bottom of the screen, or lets the bonus timer reach zero. The game ends when all lives are lost. Donkey Kong Jr. has a kill screen at level 22.

Donkey Kong has been defeated by Mario, who has put him in a cage in a forest. Donkey Kong's son, Donkey Kong Jr., follows Mario in an attempt to free his father. Mario transports Donkey Kong to his Hideout via helicopter, before Mario takes the keys to Donkey Kong's chains and places them around the building. Several enemies attack Donkey Kong Jr., but he escapes them and makes it to his father, releasing him from the chains as Mario falls to the ground. Donkey Kong Jr. saves Donkey Kong and the two set off together. Mario pursues the kongs, but flees after Donkey Kong knocks him back.

During Donkey Kongs development in 1981, Shigeru Miyamoto's team had come up with several ideas and complete levels that would not fit into the game. They eventually began fleshing out these concepts, and these designs evolved into something all their own. The process was so far along, with even entire stages conceived, that one of the team members suggested they start working on another game. The conversation happened around the same time that Nintendo wanted another Donkey Kong coin-op to capitalize on the original's popularity, giving Miyamoto the opportunity to explore his newly established series. Originally, Miyamoto wanted the new game to star Donkey Kong himself, but there were problems with the character's large size. They came up with the idea to make a smaller Donkey Kong who would be the son of Donkey Kong. Since they still wanted a big Donkey Kong on top of the screen, they came up with the plot of Mario capturing him after the events of the first game.

Due to the level counter only having one digit, the counter shows numbers 1 to 9 in levels 1 to 9, seven blanks in levels 10 to 16, and the letters A to F in the levels 17–22. The kill screen occurs the same way as in Donkey Kong, where an integer overflow occurs after too big a result is given after a multiplication problem in the computing. The timer counts as if there are 700 points, then kills Donkey Kong Jr. until all lives are gone.

• Illustration — New Wide Screen Game & Watch Donkey Kong Jr. The order of the levels is different in different territories. In the Japanese version, the four levels appear in 1-2-3-4 sequence and then repeat, just as with the Japanese release of Donkey Kong. In the US version, the order is 1–4. 1–2–4, 1–3–4, 1-2-3-4 and then 1-2-3-4 from then on. Donkey Kong Jr. was ported to the NES, serving as one of three Japanese launch games on the Famicom. It was also ported to the Family Computer Disk System, which was released only in Japan. Atari released ports for the Atari 2600, Atari 7800, and Atari 8-bit computers, while Coleco released ports for the ColecoVision and Coleco Adam. CBS Electronics released a port for the Intellivision. A BBC Micro conversion was made but unreleased. Three Game & Watch versions of the game were also made. Two black-and-white versions for the New Wide Screen and Multi Screen handheld series (later under the model name Donkey Kong II), and a color version for the Tabletop and Panorama series. In 2002 the NES version was rereleased on the GBA add-on, the e-Reader.

On September 3, at 1984 Arcade in Springfield, Missouri, Mark L. Kiehl of Enid, Oklahoma surpassed Wiebe's record with a score of 1,147,800. Steve Wiebe regained the record with a score of 1,190,400 on his home machine set on Tuesday, February 16, 2010. Mark Kiehl has since eclipsed the previous world record with a score of 1,307,500. In November 2016, Kiehl improved the record with a score of 1,412,200. On July 3, 2023, Justin Elliott performed a score of 1,584,400 live on his Twitch channel to secure the World Record. The score was independently verified by the Donkey Kong Forum as well as Twin Galaxies.

The game spawned a cereal with fruit-flavored cereal pieces shaped like bananas and cherries. The game was featured on numerous episodes of Starcade. Host Geoff Edwards noted that he had the arcade machine in his dressing room and found the game to be highly difficult. Donkey Kong Jr. was featured in Saturday Supercade (a series that aired on Saturday mornings from 1983 to 1985) with the title character voiced by Frank Welker. Donkey Kong Jr. is one of the 8 playable characters in Super Mario Kart for the SNES. This version was released as a racer in Mario Kart Tour alongside Mario from the same game in 2020. He is also a playable character in Mario's Tennis on Virtual Boy and Mario Tennis on the Nintendo 64. In the version of Super Mario Bros. 3 seen in Super Mario All-Stars, as well as the Game Boy Advance version, the king of World 4 was transformed into a young gorilla identical to Donkey Kong Jr. Donkey Kong Jr. is among the characters in Super Mario Maker that players can transform into by use of Mystery Mushrooms.
