Rax

Rax is a puzzle sandbox about directing light, solving logic challenges and building modular systems. You use optical components to control the direction, color and timing of light, progressing from simple routing puzzles to challenges involving color mixing, delayed signals, state control and reusable chip design.

Light and logic

Puzzles use a grid where light can travel horizontally, vertically and diagonally. Components include mirrors, prisms, delay mirrors, heat and cryo mirrors, and one-way mirrors, each with distinct rules and uses. You can split and merge colors, delay or block light, and control conditional activation.

Build and reuse

Rax includes structured level challenges and a Free Lab mode. Levels have clear objectives and optional star challenges. In Free Lab, you can build larger systems, debug and experiment, then package useful light circuits as blueprint chips to combine, test and refine as reusable modules.
