Laser Lab
- Tap or click a mirror to turn it from / to \ and back (with the keyboard: arrows to pick a square, space to turn).
- The laser starts from the cannon, bounces off the mirrors and stops at metal blocks or the edge of the bench.
- A crystal is lit only while the laser passes through it: the level is solved when they're all lit at the same time.
- You have 90 seconds; each solved level adds 15 seconds and is worth 10 points plus 1 point for every 10 seconds left.
- The bench grows from 5×5 to 7×7 squares; the game ends when the timer reaches zero.
What is Laser Lab?
In the Laser Lab a cannon fires a laser beam that always travels straight. On the bench there are rotating mirrors, metal blocks that stop the light and sensor crystals that must all light up together to switch the system on. Every layout is generated on the spot and always has a solution; the more levels you solve, the bigger the bench gets.

Tips
- Follow the laser backwards: start from the furthest crystal and work out which mirror the beam has to come from.
- Not every mirror is needed: some are there to trick you.
- Solve the first levels quickly: the seconds you have left are worth extra points.
