About Beam Splitter
Route coloured beams of light through a dark lab by flipping mirrors, until every crystal glows. Splitters double your beams and shadow crystals punish a stray ray. Neon-lit and very satisfying when it clicks.
Tap mirrors to route the beams

How to play Beam Splitter
Rules
- Tap a mirror to flip it. Beams bounce off mirrors at right angles.
- Light every crystal with a beam of its own colour.
Controls
- Tap a mirror with a pink ring. Mirrors without a ring are fixed. The goal bar above the board shows which crystals are lit.
Later on
- Splitters (from level 10) send light two ways at once: straight through and around the corner.
- Shadow crystals (from level 18) must stay dark. Keep every beam off them.
Fewer moves earn more stars: three at par. Undo takes back a move (3 per level). Hint shows the best next move.
