How to Play Laser Mirrors
- Tap a mirror to rotate it 90°, redirecting the laser beam.
- The beam travels in a straight line until it hits a mirror, wall, splitter, portal, filter, or crystal.
- Splitters fork one beam into two; portals teleport the beam to its paired portal; color filters only let matching-color beams through.
- Light every target crystal at once to complete the level.
- Fewer rotations earns more stars — the "Best Known" chip shows the minimum possible.
- Stuck? Use Hint to reveal one correct rotation, or Undo to take back your last move.
