VOLT vs Light Up Grid

Rotate. Connect. Light it up. Turn the circuit pieces so power flows from the source to every bulb on the board. No numbers, no clutter—just tap a piece to rotate it. The rules take seconds to learn, but the solving goes surprisingly deep. HOW TO PLAY Trace the wiring from the golden power source and get electricity to every bulb. Tap a piece to rotate it 90° clockwise; press and hold to turn it back. Live wires glow like neon, so you can always see how far the current reaches. Leave no loose ends—no wire pointing at nothing—light every bulb, and the circuit is complete. WHAT MAKES VOLT DIFFERENT - There's always exactly one answer. Every puzzle is verified by a dedicated solver and shipped only if it has a unique solution.
