Proto:Donkey Kong Jr. Math

This page details one or more prototype versions of Donkey Kong Jr. Math.

Donkey Kong Jr. + Jr. Sansuu Lesson is a compilation of Donkey Kong Jr. and Donkey Kong Jr. Math, released in October 1983 as a pack-in game for the Sharp C1 Famicom TV.

Notably, Jr. Math (which wouldn't be released in standalone form until December) is an early version with some interesting differences. Only the +-×÷ Exercise mode is present, under the name "Jr Lesson +-×÷".

Math Screen

• Donkey Kong is in a cage. Interestingly, the sprite used for him here is an unused sprite from the original game.
• The current and high score aren't present. The amount of time elapsed is shown instead.
• The Nitpicker on the left is absent. Instead of it laying eggs to show correct answers, apples appear next to the question numbers.
• Pressing Start sends you back to the selection screen instead of pausing the game.
• The number 8 matches its appearance in the original Donkey Kong Jr. (and by extension Atari's Quiz Show where the font originated). It was changed to a more standard design, likely for legibility reasons.
• The chains are a pixel further to the right.
