To do:
Document Donkey Kong Jr. + Jr. Sansuu Lesson.

The Donkey Kong family teaches math in Donkey Kong Jr. Math, the only entry in the NES' "Education Series" label. While it was later released on Virtual Console, it is not part of the Switch's online service of NES/Famicom titles.

Donkey Kong Jr. Leftovers

To do:
There's more leftovers in the Japanese version.

Most of the game's CHR ROM was directly copied from Donkey Kong Jr. As a result, some of that game's graphics go unused.

Add! Now multiply! Faster! FASTER! Oooof...

Mario! Sadly, he doesn't actually appear in this game.

Raise 'a roof

Junior with his hands up, originally used when catching his father.


A sprite of Donkey Kong (and an extra set of face tiles). Unlike all of his used sprites in this game, he is not shown holding the sign.

Fruit is good for you too, ya know

The fruits, also not found anywhere.

Bombs away...!

Nitpickers flying downward. Only their horizontal sprites are used.

Danger: High voltage

The Sparks from Stage 3 of the original game.

Regional Differences

Japan International

The Japanese version has a rather primitive-looking logo, using the same style as the one seen in its Japan-only sister game Popeye no Eigo Asobi. The international version is far more detailed and colorful, with the new graphics overwriting some of the Donkey Kong Jr. leftovers.

Of note is that, like Popeye no Eigo Asobi, the Japanese title screen doesn't use the full name of the game for whatever reason, simply reading Sansuu Asobi.
