Mario Bros. is a Game & Watch Multi Screen series game by Nintendo released on March 14, 1983. Despite the title, it is unrelated in gameplay to the Mario Bros. arcade game. It is the first appearance of Luigi, as the Game & Watch version predates the arcade game by almost two weeks.
In this game, Luigi is on the left screen and Mario is on the right screen. The game's clamshell design is unusual in the series; it opens horizontally like a book (in the Japanese right to left reading order) and not vertically (like the Nintendo DS).[5] The brothers are working in a bottling plant, moving packages between the various levels of the bottling machine.
The only controls for the game are up and down buttons for each brother. Mario first gets a pallet out of the machine on the lowest level and puts in on the conveyor belt. Luigi then takes it from the other side and puts it on the belt above it. There are 3 points on each side the brothers must do this. Finally, once the package is filled Luigi tosses it onto the delivery truck. Once the truck is full, the brothers get a short break. If the brothers drop a pallet, they are yelled at by their bosses. If three pallets are dropped, the game will end.
 
Like nearly all Game & Watch titles, Mario Bros. features the standard Game A and tougher Game B.
