Mickey Mouse © 1981 Nintendo Co., Ltd.
The player controls Mickey Mouse whose task it is to catch eggs as they roll down four slopes, two on either side of the screen. If an egg is dropped it lands on the floor releasing a chick who walks away off screen. The eggs fall ever more quickly as the total caught closes in on multiples of 100.
Model MC-25
Released on October 9, 1981 (Friday) in Japan.
In Australia and some Asian countries, Nintendo wasn't allowed to release the wide screen game due to copyright issues with Disney in those countries. So instead they released a game titled Egg, with the only difference being a change of characters.
Collectors attempting to collect every edition of a Game&Watch video game box would have to collect four different standard version Mickey Mouse video game boxes.
