Read full description

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. You get there by logic, never by guessing. - Difficulty grows with the depth of the read, not just the size of the board. Hard and Expert puzzles are built so you can't finish on forced moves alone—real challenge for experienced players. - No numbers required. If sudoku isn't your thing, you'll feel right at home. It's pure, intuitive, and works in any language. FOUR DIFFICULTIES - Easy (5×5): a gentle start you can solve on forced moves. - Medium (7×7): a satisfying bit of thinking. - Hard (8×8): always demands a deeper read somewhere. - Expert (9×9): the real thing—hold the whole board in your head. A PUZZLE EVERY DAY A fresh "Daily Circuit" everyone in the world plays together. Keep your streak alive and make it a habit. MADE FOR YOU IF - You want to sharpen your mind on a commute or a coffee break - You're tired of number puzzles—or numbers just aren't your thing - You love Pipes, Netwalk, or loop-style puzzles - You want a calm wind-down ritual before bed - You're hunting for puzzles that are genuinely hard, not just big PRIVACY & PEACE OF MIND - No account needed. Just open and play. - Your records stay on your iPhone. Nothing is sent to a server. - Fully offline—play anywhere, no signal required.
