Wire up the circuit and light the bulb! Spot open vs closed circuits, tell conductors from insulators, and build series & parallel loops.
Pick your starting grade:
Tap an answer (or press 1–4, or Y/N). Correct answers charge your power meter toward the next level and build a streak for bonus points. A wrong answer drains a ⚡ charge — lose all three and the circuit goes dark. The game learns your weak spots and drills them more. 💡
