Brass mirror and glass receiver Lumenrook icon

Follow the actual light.

Every turn redraws the real ray. Mirrors change its path, splitters create two routes, and RGB filters select the colors that pass.

Mix the right color.

Receivers combine incoming rays. Yellow, cyan, magenta and white require the right mix, not just any beam.

Earn a new cabinet.

Four different clears open the next setting. Revisit the old apparatuses and find a solution within their tested turn budget.

Build your own experiment.

Save sixteen named, working apparatuses. A validated arrangement becomes a scrambled puzzle. Share its image and JSON design through your device.
