How to play
- Press the green flag. Look at the fish’s weight and its distance from the pivot.
- Add weights to the holes on the right. Change their positions until you think both sides will balance.
- Choose 答え合わせ (Check answer) to test your prediction.
Blue 増やす means add; red 減らす means remove. Each weight is 10 g, with up to ten weights at one position. Use the arrows beside Level to change the challenge. Level 2 removes one hanging point; Level 3 moves the pivot.
For families and teachers
Compare weight × distance from the pivot on each side. Try more than one arrangement rather than relying on total weight alone.
