About Laser Puzzle

Laser Puzzle asks you to bend the lasers that shoot from the edge of the board with mirrors until every target is hit. Tap a rotatable mirror to flip it between / and \, and the beam updates on screen right away. The 150 stages grow from a 5x5 board with one laser to a 7x7 board with three; from stage 40 some mirrors are hidden in fog, and every stage is solvable with a known minimum number of rotations.

How to play

1. A red box is a laser and shoots a beam in the arrow's direction. The beam goes straight, bends at mirrors, stops at walls and other lasers, and disappears when it leaves the board.
2. Tap a mirror with a blue ring to flip it between / and \. Gray mirrors are fixed and walls never move.
3. A yellow circle is a target. It lights up when a beam hits it, and the beam stops there, so it does not continue behind a target. Light every target to clear the stage.
4. The top shows how many targets are lit, and the top bar shows your rotations so far and the minimum. Restart returns to the starting state.
5. Stars depend on rotations: within minimum +1 is 3 stars, within twice the minimum +2 is 2 stars, more is 1 star. Using Hint (it marks the next mirror to rotate) caps you at 2 stars. Clearing a stage unlocks the next, and progress is saved on this device.

Tips

• Work backwards from a target: decide which direction its beam must arrive from and the mirrors you need become clear.
• Many mirrors look important, but only a few actually carry a beam. Ignore the ones no light reaches.
• Rotating one mirror changes everything behind it, so fix the mirrors closest to the laser first.
• With several lasers, one beam's path can block another's. Check that they do not get in each other's way.
