The games of the first genre are mostly single-screen platform/action puzzle types, featuring Donkey Kong as the in an industrial construction setting. Donkey Kong first made his appearance in the 1981 arcade machine called "Donkey Kong", in which he faced Jumpman (Mario). This game was also the first appearance of Mario, pre-dating the iconic video game "Super Mario Bros." by four years and Mario's first non-"Donkey Kong" game ("Mario Bros.") by two. In 1994, the series was revived as the "Donkey Kong Country" series, featuring Donkey Kong and his clan of other apes as protagonists in their native jungle setting versus a variety of anthropomorphic enemies, usually against the Kremlings, a clan of crocodiles and their leader King K. Rool. These are side-scrolling platform games. Titles outside these two genres have included rhythm games ("Donkey Konga"), racing games ("Diddy Kong Racing") and edutainment ("Donkey Kong Jr. Math").
