How to play Laser Mirror Puzzle
- Choose a level. New levels open as you solve them, and each pack opens when you have solved 6 levels of the pack before it.
- Tap a mirror with turn arrows to turn it. Mirrors with bolts are fixed and cannot move.
- Pieces in the tray are yours to place: tap an empty square to put the chosen piece there, tap it again to turn it, and drag it off the board to put it back.
- Light every target to finish the level. Solve it in the fewest moves for 3 stars. A hint shows one piece of the answer but costs a star.

About Laser Mirror Puzzle
Light travels in straight lines until it hits something. When it hits a mirror it bounces off, and it always leaves at the same angle it arrived: the angle in equals the angle out. This is the law of reflection. In this game every mirror sits on a slant at 45°, so a beam that hits it always turns a right angle. Children quickly learn to predict where a beam will go, which is exactly how periscopes, kaleidoscopes and the mirrors in a car work.
The 40 puzzles come in four packs that add one idea at a time. Easy, for Grades 2–3, starts with mirrors you turn, then mirrors you place yourself, alongside fixed mirrors that cannot move. Medium, for Grade 4, adds beam splitters: glass that lets half the light through and reflects the other half, so one beam can light two targets. Hard, for Grade 5, adds coloured lasers and colour filters. White light is a mix of colours, and a red filter only lets the red part through, so a white beam becomes red, while a blue beam is stopped. Expert, for Grade 6, mixes everything with several lasers and targets. Every level was checked by a computer solver to make sure it can be solved, is not already solved at the start, and needs every piece in the tray.

Frequently asked questions
How does light reflect off a mirror?
Light bounces off a mirror at the same angle it hits it. If you draw a line straight out from the mirror, the angle between that line and the beam coming in is always the same as the angle between the line and the beam going out. Because the mirrors in this game are slanted at 45°, a beam turns exactly 90°: a beam going right hits a / mirror and goes up, and hits a \ mirror and goes down.
What does a beam splitter do?
A beam splitter is a special piece of glass that is partly a mirror. Some of the light passes straight through and the rest is reflected, so one beam becomes two. Real beam splitters are used in cameras, microscopes and science experiments.
Why does the coloured target not light up?
A coloured target needs light of its own colour. White light contains all the colours, so a white beam can be turned red, green or blue by passing it through a filter of that colour. A filter blocks light of any other colour, so a blue beam cannot get through a red filter.
How do I get 3 stars?
Finish the level in the fewest moves you can, without a hint. Every turn, placement, move or pick-up counts as a move. The star pill at the top shows how you are doing, and the results screen shows the fewest moves possible.
Can I play with a keyboard?
Yes. Press Tab to reach the board, use the arrow keys to move the yellow box, press Enter to place or turn a piece, Delete to pick a piece up, the number keys to choose a tray piece and H for a hint.
