Laser mirror puzzle online
A laser fires across a grid, and somewhere on the board a receiver waits for it. Place and turn mirrors to bounce the beam around the walls and into every receiver. The beam redraws the moment you move a piece, so you can feel your way to the answer. There is no timer and no way to lose.
How to play
- Drag a piece from the tray onto any empty square. Drag it off the board to put it back.
- Tap a piece to turn it.
- Pieces with a lock can't move. Teal pieces with arrows stay put but can still turn.
- Light up every receiver to clear the level.
The pieces
- Mirror: turns the beam 90 degrees, left or right depending on which way it faces.
- Beam splitter: half the light passes straight through and half is reflected, so one beam becomes two.
- Crystal: splits a beam three ways: straight on, left and right.
- Portals: a beam that enters one portal leaves its twin, still heading the same way.
Mystery crates
Some levels hide a crate marked with a question mark, usually a little off the obvious route. Send the laser through it to open it. Inside you may find a hammer that smashes any wall, a bonus mirror for the level, extra hints, or a key. Collect keys to open secret treasure rooms: big boards full of crystals that end in a light show.

How do I play?
Drag mirrors from the tray onto the board and tap a mirror to turn it. The beam updates as you move pieces. Light up every receiver to clear the level.
What do the different pieces do?
A mirror turns the beam 90 degrees. A beam splitter lets half the beam through and turns the other half, so one beam becomes two. A crystal splits one beam into three. Portals send a beam in one side and out of the twin portal.
What is in the mystery crates?
