How to play
- Click the green flag and look at the two starting numbers.
- Use メモ1 and メモ2 to mark multiples of each number.
- Use 回答する to answer with multiples common to both.
メモ1 and メモ2 mean “Memo 1” and “Memo 2”. 回答する means “Answer”. The original buttons and prompts remain in Japanese.
For families and teachers
A common multiple appears in both multiplication sequences. Marking the two sequences can show why their shared numbers repeat.
This English guide uses the original Chicodori Scratch project. Some labels remain in Japanese. You can explore and remix the project on Scratch.
