How to play
- Press the green flag. Read the challenge using the word guide below.
- Tap the grid to place components. Keep changing the cells until your circuit matches the challenge.
- Choose 答合わせ (Check answer) in the top-right corner. Look at the result and try another arrangement.
Word guide: 電球 = bulb; 電池 = battery; 直列 = series (one after another); 並列 = parallel (separate branches); 2つ = two. For example, 電球を2つ並列に、電池を2つ直列につないだ回路 means two bulbs in parallel with two batteries in series. The challenge text remains in Japanese.
For families and teachers
Ask learners to trace a complete path through the circuit and compare series and parallel arrangements. This is an on-screen model, rather than a substitute for safe, supervised practical work.
This English guide uses the original Chicodori Scratch project. Some labels remain in Japanese. You can explore and remix the project on Scratch.
