It has received criticism from several publications includingIGN staff, who called it one of the worst Virtual Console games.
Bruce Lowry, Nintendo of America’s vice president of sales from 1981 to 1986, referred to it as “the worst game we ever sold.”[3]

The game features two modes, one single-player and the allowing for one to two players.[4][5] Its mechanics are similar to its predecessor,Donkey Kong Jr.[4] The Calculate mode has Donkey Kong hold up a number, which players must attempt to reach by collecting a combination of digits and arithmetic symbols to eventually reach that number.[4] Players must climb vines to reach these figures.[6] The +−×÷ Exercise requires players to solve fixed math puzzles by climbing chains to reach the correct numbers and arithmetic symbols to do so.[4][6]

The game was first released in Japan on December 12, 1983, and was released shortly after together withDonkey Kong Jr. as a licensedmulticart (released in a bundle together withSharp'sC1 Famicom TV).[1][12] In August 1995, the Sharp multicart was re-released separately from the C1 Famicom TV.[12] The game has been released on other platforms, including the video gameAnimal Crossing, which featured several NES games.[13]Donkey Kong Jr. Math was re-released on theWii'sVirtual Console in Japan on March 27, 2007,[14] Europe and Australia on April 20, and in North America on September 3.[1] It was re-released again for theWii U'sVirtual Console in North America on August 28, 2014, in Europe on January 22, 2015, and in Japan on April 15.[1][15]
