Donkey Kong Jr. Math

Donkey Kong Jr. Math, originally released in Japan as Donkey Kong Jr. no Sansū Asobi (Japanese: ドンキーコングJR.の算数遊び, Hepburn: Donkī Kongu Junia no Sansū Asobi) (sometimes released as Jr. Sansū Lesson (JR.算数レッスン, Junia Sansū Ressun)), is a Nintendo edutainment video game where players must solve math problems in order to win. It was released in Japan in 1983 for the Family Computer, in North America in June 1986, and in PAL regions in 1986. It is the only game in the "Education Series" of NES games in North America. Donkey Kong Jr. Math was made available in the video game Animal Crossing (along with several other NES titles). Donkey Kong Jr. Math was re-released on the Wii's Virtual Console in 2007 and on the Wii U's Virtual Console in 2014.

Since its release, Donkey Kong Jr. Math has received very negative reception; Nintendo spokesman Tom Sarris commented that it was not well received, resulting in Nintendo ceasing development of educational games for the time. It has received criticism from several publications including IGN, who called it one of the worst Virtual Console games.
