How to Play Donkey Kong Jr. no Sansuu Asobi
Quick start
Select the mode with SELECT and confirm with START. First, practice with EXERCISE, move the chain with the D-pad, and jump with A to capture the numbers. In CALCULATE, be aware of the order of numbers → symbols → numbers and get closer to the target value. If you make a mistake in the formula, you can reset the answer with B, but you cannot erase the starting value of CALCULATE B itself.
Controls
D-pad: Move, go up and down chains, select items. A: Jump. B: Calculation formula/reset answer. SELECT: Return to title/select mode by title. START: Decision/Pause during game. CALCULATE operates each Jr. with controllers 1 and 2.
Donkey Kong Jr. no Sansuu Asobi — About this game
``Donkey Kong JR.'s Math Game'' is an educational action where children go up and down the chain, take numbers and +, -, ×, ÷, and bring the calculation results closer to the target value indicated by Donkey Kong. In CALCULATE A/B, 1 or 2 players aim to win 5 games first, and in B, difficult problems involving negative numbers are also asked. EXERCISE is for one person and consists of 10 questions where you fill in the blanks in order. In a match, you can also interfere with your opponent getting the number they want first.
