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
Everything you need to get started.
-
01
The goal: illuminate every crystal in the level with the laser beam, each crystal in its own matching colour.
-
02
Some tiles are fixed; others are movable — you can spot them by their subtle wobble. Swipe a movable tile to push it; it slides until it hits an obstacle.
-
03
A white laser enters the level from the centre of the left edge after a set time, or you can start it manually at any point.
-
04
Mirrors redirect the laser beam in a new direction. Splitters divide it into two or three separate beams.
-
05
Colour-splitter tiles break the beam into its additive primaries (red, green, blue) or strip out a single colour, leaving the remainder of the beam intact.
-
06
Other elements — bombs (explode when hit by the laser), balloons (disappear when hit, but block tile movement), blockers, doors and more — are introduced in the Tutorial level pack and the Classic level pack.
-
07
Optrix is divided into levelpacks, each containing a collection of levels to play through.
-
08
Most levelpacks use a star-based progression system. Completing a level earns one star; staying within the step limit earns two. Once you have enough stars, additional levels in the pack unlock.

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.
Current status
Optrix is still in testing and is being actively developed. You can play in the browser any time at game-app.html; install the iOS app via the button at the top of the hero.
