RAX is a puzzle sandbox about light paths, logic, and modular construction. Place and rotate optical components to control the direction, color, and timing of light, activate targets, and package complex circuits into reusable blueprint chips.

RAX is a puzzle sandbox about light paths, logic, and modular construction.Use mirrors, prisms, delay mirrors, heat and cryo mirrors, one-way mirrors, and other optical components to control the direction, color, and timing of light. As the levels progress, simple routing puzzles gradually grow into challenges about color mixing, delayed signals, state control, and reusable chip design.The game includes structured level challenges as well as a Free Lab mode. In Free Lab, you can build larger systems, package useful light circuits into blueprint chips, then combine, test, and refine them.Key Features:<ul class="bb_ul"><li>Grid-based light-path puzzles with horizontal, vertical, and diagonal propagation.</li><li>A focused set of optical components, each with distinct rules and uses.</li><li>Mechanics for color splitting, color merging, delay, blocking, and conditional activation.</li><li>Blueprint and chip systems for turning complex structures into reusable modules.</li><li>Level mode with clear objectives and optional star challenges.</li><li>Free Lab mode for open-ended building, debugging, and experimentation.</li></ul>If you enjoy logic circuits, optical puzzles, automation systems, or building complex behavior from simple rules, RAX offers a quiet but deeply systemic space to explore.
