The goal
A beam shoots from each emitter. Rotate the mirrors so the light reaches every target ring in its matching colour.
Mirrors
Tap a glowing mirror to flip it between / and \. Each flip bends the beam 90°.
Filters
A coloured filter tints the beam passing through it — white light through a red filter becomes red.
Par
Par is the fewest moves needed. Beat it for a ⭐️.
