Mario Bros. (Game & Watch)

Mario Bros. is a title for the Game & Watch. Despite its name, it has no similarity to the popular arcade game Mario Bros. Instead of plumbing, Mario and Luigi are working at a bottling factory and must prepare packages of bottles to load onto a delivery truck. This is the first game to feature Luigi.

The game is played on the Multi-Screen model of Game & Watch, and was released on March 14, 1983. The model opened like a book, and could allow for simultaneous two-player action, with one player controlling Luigi on the left half of the game and the other playing Mario on the right.

Gameplay
Mario must first take a pallet out of the machine on the lowest level and place on the lowest of five conveyor belts running in alternating directions. A bottle is placed on the pallet as it passes through the divisor between the screens and continues on until it reaches the end of the conveyor belt. Here, Luigi must take the package and place it on the above conveyor belt which takes it back to Mario, who sends it back to Luigi on the next conveyor belt. Luigi sends it back again and Mario has to put it on the highest conveyor belt, where it is sealed while passing through the column. Luigi then throws the sealed package to the delivery truck, which eventually gets filled up and leaves, giving Mario and Luigi a brief break until it returns empty.

There is no end to the game but the conveyor belts get faster and the number of pallets on the screen increases as time goes by, forcing Mario and Luigi to scramble up and down the ladders in order to prevent the packages from falling off the ends of the belts. Each time this happens the Mario Bros. get yelled at by their boss. After three misses it is Game Over.

If the player manages to score 300 points without a single miss, the points that are earned will be doubled until the player does get a miss. If a miss is earned before scoring 300 points, all misses will be cleared instead.

In this game, Mario Bros. is re-released with an updated Modern Mode as well as the classic mode. The Modern Mode has many changes: Mario and Luigi are working in a cake factory; Wario drives the delivery truck; and Bowser frequently appears and reverses the direction of the conveyor belts, forcing either Mario or Luigi to flip one of two switches at the bottom of the screen to switch them back to normal. Up and Down on the will make Luigi Move, and  and  will make Mario move up and down respectively.

Trivia

 * Mr. Game & Watch's forward-aerial attack in the Super Smash Bros. series involves swinging a package, much like Mario and Luigi do in this game. Additionally, Mr. Game & Watch's down taunt in Super Smash Bros. for Nintendo 3DS / Wii U is based on Mario and Luigi's animation after finishing a level.
