Circuit Flow

1. Tap a tile to rotate it clockwise (right click or Shift to rotate counter-clockwise).
2. Two tiles connect only when both have a wire end facing each other.
3. Light every lamp. Every tile must carry signal and no wire end may stay open.
4. Pinned tiles cannot rotate. Switch tiles toggle between two shapes.
5. On hard levels the number of moves is limited.

1. Power the lamp. The source sends a signal along connected wires. Lit wires show where it flows.
2. Rotate. Tap a tile to turn it. Connections only count when both ends face each other.
3. Seal the circuit. Every wire end has to connect somewhere. Open ends are marked.
