Donkey Kong Jr. Math, known in Japan as Donkey Kong Jr. no Sansū Asobi (ドンキーコングJR.の算数遊び, Donkī Kongu JR. no Sansū Asobi?, lit. "Donkey Kong Jr.'s Calculation Game") (also JR. Math Lesson (JR.算数レッスン, JR. Sansū Ressun?)), is a Nintendo edutainment video game released for the Nintendo Entertainment System (NES), wherein players must solve math problems in order to win. It was released in 1983 for the Family Computer in Japan and then for the Nintendo Entertainment System two years later in North America and PAL regions. 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. It has also been released on the Wii Virtual Console in Europe, Australia, Japan, and North America.
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 was noted as one of the worst launch video games ever made by publications such as Electronic Gaming Monthly and 1UP.com. It has also received criticism from several publications including IGN, who called it one of the worst Virtual Console games. The game was the worst-selling game in the NES' launch library in the US.
