Basics

Tap any tile to rotate it 90° clockwise. Rotate tiles until every receiver is powered by the energy source.

Power flows through tiles only when both touching edges have an open circuit line. A gap breaks the circuit.

Goal

Every receiver (green ring) must be lit. When the whole circuit is complete, the level is solved.
