How to play
- Tap a piece to turn it. A mirror tilts, a filter changes colour, a prism or portal turns clockwise.
- Follow the beam from each light source. Every target ring must shine in its own colour; the letter on it names that colour.
- Lock pieces you trust. Keep every beam away from dark matter.
Controls
Click or Space turns. Right-click, long-press or L locks. Arrows move. Z undoes, Y redoes, H hints.
About this game
Free 30-level light puzzle. Red, green and blue beams bend off mirrors, split, pass colour filters, blend in prisms and jump through portals; a beam that touches dark matter overloads the board. An exact solver checks every level: each has one winning layout, so par is the true minimum number of turns, and three stars need par without a hint.
