Prism Flow: Brain Puzzles

Prism Flow is a quiet optics bench with endless puzzles. Route colored light with mirrors and prisms. Mix blue and yellow to make green when a crystal asks for it. Progress stays on this phone. There is no timer and no fail state. A beam either reaches the right target or it does not, and you keep editing the board. Place a mirror to turn a corner. A combiner waits until two colors occupy the same place, then one mixed color leaves the tip. A splitter turns one path into two. A filter keeps a single channel. Shapes mark each channel so hue is not the only cue. Red is a circle. Yellow is a triangle. Blue is a square. Each solve feeds a small prism sail docked in the Light cabinet. When the lantern is full, you send it. The bench stays. After the tutorial the bench keeps dealing boards. No account. No ads. No analytics. No shop that sells the next color. $2.99 once.
