Laser Logic
Turn mirrors, slide glass and split light to power every receiver — 50 handcrafted laser puzzles.
About the Game
Laser Logic is an original beam-routing puzzle with 50 handcrafted levels. Emitters fire red, green and blue lasers across an optics bench, and you guide them: tap a mirror to turn it, drag sliding mirrors, blocks and colour filters one cell at a time, and watch the light travel through the scene after every move. A level is solved when every receiver gets exactly the colour it asks for — and colours mix, so a yellow receiver needs red and green together, and a white one needs all three. Five chapters introduce the tools in turn: First Light covers mirrors, splitters and sliding pieces; Spectrum brings colour filters and mixing; Gateways adds portals that carry a beam through walls and sensors that hold gates open; Crystal Hazards places crystal mines that shatter if any beam touches them, so the order of your moves matters; and Grand Optics ends with expert machines and a final level played with no undo. Every level's par is the fewest moves possible, proven by an exhaustive search of the game's own rules.
How to Play
Each emitter fires a beam in a straight line. Mirrors turn a beam by 90°, splitters let it pass and send a copy sideways, and walls, blocks and emitters stop it. Mirrors with a dashed cyan ring can be turned: tap one to flip it. Pieces with orange grips slide: drag them one cell at a time, or tap one and then tap a neighbouring cell. Receivers show the colour they need around their rim and light up when they get exactly that colour — red, green and blue mix, so yellow is red plus green, cyan is green plus blue, magenta is red plus blue, and white needs all three. Colour filters only let their own colour through. A beam that enters a portal comes out of its twin travelling the same way. A sensor holds its matching gate open while a beam is on it. Crystal mines shatter the moment any beam touches them, which ends the level, so think about the order of your moves. Light every receiver to finish; matching the level's par earns three stars.

Gameplay Tips
- Follow the beam from the emitter and fix the first wrong mirror you meet.
- On crystal levels, turn the far mirrors first so the light never takes a wrong turn on the way.
- A receiver that glows grey is getting the wrong colour — look for a beam that shouldn't be there.
- Splitters always send light both ways; make sure the second branch ends somewhere safe.
- Sliding pieces can travel further than they look — check the long way round.
FAQ
What is Laser Logic?
Laser Logic is a free laser puzzle game on ZOQSY. You turn mirrors and slide pieces to guide coloured beams so that every receiver gets exactly the colour it needs.
How many levels are there?
50 handcrafted levels in five chapters, from a one-move tutorial to the final level, Final Light, which is played with no undo.
How does colour mixing work?
Beams are red, green or blue. A receiver lights when the colours reaching it add up to its colour — yellow is red plus green, cyan is green plus blue, magenta is red plus blue, and white is all three.
What happens if a beam hits a crystal?
Crystal mines shatter as soon as any beam touches them and the level is lost, so on crystal levels the order of your moves matters. You can undo or retry.
How do I get three stars?
Solve the level in its par — the fewest moves possible, which the game's verifier proves for every level. Two extra moves still earn two stars.
Can I play on my phone?
Yes. Tap mirrors to turn them and drag sliding pieces with your finger. It also plays with a mouse or keyboard.
Is Laser Logic free?
Yes — free in your browser with no download or account. Stars and best results are saved locally in your browser.
