Laser Lab
Play Laser Lab free online. Turn mirrors and beam splitters so the laser bounces into every crystal target at once. 25 labs, each one built to be solvable.
How to Play Laser Lab
Each lab is a dark grid with a laser on one side, a few crystal targets and a set of mirrors. The laser fires in a straight line. Your job is to turn the mirrors so the beam bounces around the room and lights every target at the same time.
Tap a mirror to turn it between its two angles. A mirror bounces the beam off to the side. A splitter, the half-silvered piece, lets the beam carry straight on and also bounces a copy off to the side, so one beam can become two.
Walls block the beam, and some labs have extra mirrors that are not part of the answer. From lab 10 on, some pieces are bolted down and cannot be turned. When every target is lit, the lab is solved and the next one loads.
Each lab solved scores 100 points plus a time bonus for solving it quickly. There are 25 labs in all, and every one is built so it can always be solved. End run finishes the game early with your score so far.
Controls
Touch
- Tap a mirror or splitter to turn it. Tap End run twice to finish early.
Mouse
- Click a mirror or splitter to turn it.
Keyboard
- The arrow keys move the cursor, and Space or Enter turns the piece under it. X twice ends the run. P or Escape pauses, M mutes.
Tips and Tricks
- Start from the laser and follow the beam one mirror at a time. Fix the first wrong bounce before worrying about the rest.
- Work backwards from a target too. Ask which mirror could send a beam into it.
- Bolted pieces are clues. They are part of the route, so build the rest of the path around them.
- If two targets sit in different directions, the answer almost always uses a splitter.
About the Game
Laser Lab is a light-bending logic puzzle. The rules are tiny, two angles per piece, but routing one beam through a crowded room to several targets at once takes careful thinking.
Each lab is built from a fixed seed, checked to make sure it has a solution, and then scrambled. The look is a dark science lab with glowing red beams and green crystals. Your best score is kept in this browser and can go on the Top 10 board.
Laser Lab FAQ
What does a beam splitter do?
It lets the laser pass straight through and also bounces a copy to the side, so one beam becomes two.
Why will some mirrors not turn?
From lab 10 on, some pieces are bolted down. They show bolts in their corners and stay at their angle.
Is every lab solvable?
Yes. Each lab is checked by the game when it is made, so there is always a way to light every target.
How does the laser lab time bonus work?
Solve a lab in under a minute and you get 3 bonus points for every second left of that minute.
