What is Optrix?
A single-player puzzle game about light, mirrors and patience. Each level gives you a laser, a few crystals, and a grid full of optical elements. Your job: route the beam through them so every crystal lights up in its own matching colour.
Designed to be calm — no timers, no streaks, no in-app purchases, no ads, no tracking. Put it down mid-level, come back hours later; the level pack stays exactly where you left it.
How to play
Four building blocks every level is made from.
-
dark 
lit Crystals
Every crystal has to be hit by the laser in its own colour. Light them all and the level is solved.
-
dark 
lit Mirrors
Mirrors send the beam off in a new direction. A straight shot becomes a path right across the grid.
-
dark 
lit Splitters
A splitter multiplies the beam into two or three beams of the same colour.
-
dark 
lit Colour splitters
A colour splitter breaks white light into its primaries: red, green and blue.
-
Movable tiles
Some tiles can be pushed; you can spot them by their subtle wobble. Swipe one and it slides until an obstacle stops it.
-
Starting the laser
The white beam enters from the centre of the left edge after a short pause. If you would rather not wait, start it yourself.
-
More elements
Bombs, balloons, blockers and doors are introduced gradually across the Tutorial and Classic packs.
-
Level packs and stars
Solving a level earns one star, staying within the step limit earns a second. Stars unlock further levels.

Idea and Coding Alexander Gülich & Robin Glave
Originally built in 1995 in TurboPascal, just out of school, with 16-colour VGA graphics and a concept they liked more than they could execute. Rebuilt 2025/2026 in TypeScript — with modern tiles, a clean engine, and everything 1995 was missing.
