In Mario Bros. you actually control 2 characters, Mario and Luigi. They are working in a bottling plant, loading cases on a conveyor belt and onto trucks.

Game differences:

Game B requires more coordination, technique and timing.


Highest possible score is 999. When the score reaches 300 all misses are cancelled. If there are no misses scores are worth double until you get a miss.

Cheats and tricks:

Can't think of anything at the moment.


Each case loaded on a conveyor get 1 point. Each truck loaded with 8 cases gets 10 points.


When a case is dropped the foreman gets angry and you score a miss. With 3 misses (shown by 3 Faces in the upper left corner of the right screen), the game is over.

Other notices:

If you hold in Game A or Game B key the highest previous score will be displayed. If the unit is left as it is after game is over, time display will appear in about five minutes. A game is not interrupted even if TIME key or other game keys are depressed during game playing. Pressing ACL switch or removing batteries erases high score from memory.

The battery covers seem to have a number on the back, but they seem to vary a lot and I won't even speculate what the difference is.
