Nintendo has released several Mario and Donkey Kong LCD video games for the Game & Watch series.
Donkey Kong was developed by Nintendo R&D1 as part of the Game & Watch Multi Screen series, featuring two LCD screens. Released in 1982, it is a port of the arcade game, where Mario is a carpenter attempting to rescue his girlfriend from an evil, or at least angry, ape.
Like the arcade Donkey Kong, Mario must climb a building while avoiding barrels; however, beating the game is different from the arcade version. The player must trigger a lever on the upper screen, activating a hook, which Mario must then jump and catch. If the player succeeds, a peg will be removed and Mario will return to the starting point, but if the player does not, Mario will fall to the ground and lose a life. Removing all available pegs in this manner will cause Donkey Kong's platform to collapse, and he will fall to the ground.
In this 1982 game, the player controls Donkey Kong Jr. as he works to save his father, Donkey Kong, while watching out for obstacles like crocodiles, birds, and electric flashes. The game was released as part of the Mini-Classics series in 1998 (a set of four Game & Watch games ported to small keychain-bound handhelds) and was later included in the Game Boy Color Game & Watch Gallery 3 in 2000 and as DSiWare game in 2010.
In this game, Mario gives payback to Donkey Kong for stealing his girlfriend, Pauline, by locking him up in a cage.
Donkey Kong II was developed by Nintendo R&D1 and released as part of the Game & Watch Multi Screen series, featuring two LCD screens. It was released in 1983. Donkey Kong Jr. has to touch a key, then it moves up to the top screen. Donkey Kong Jr. has to climb to the top screen while avoiding things such as electrical wires. When he gets to the top screen, Donkey Kong Jr. will have to touch the key again, and it will move to the keyhole of one of the chains. Donkey Kong Jr has to climb up the rope below the keyhole, while avoiding birds. When he gets to the top of the rope, one of the chains will unlock. He has to do this 4 times until he saves Donkey Kong. After that, the game will start over, at a somewhat faster pace.
