Puzzle StudioCircuit
Learn with your hands
Real ideas. Puzzle-sized.
Every new concept arrives through play, with short explanations and no wall of formulas.
Control the current
Choose the right resistance for each LED. Too little protection can burn it out; too much leaves it dark.
Read the circuit
Cyan, yellow, and red LEDs behave differently. The board gives you the clues; you make the deduction.
Experiment without pay-to-win
Protection fuses make mistakes meaningful. They recharge over time, and optional rewarded ads can restore one.
