Prism: Light Puzzle

Prism is a calm, glowing puzzle about light. A beam leaves the lamp, bounces off your mirrors and has to reach every crystal on the board. Tap a mirror to turn it, watch the light race along its new path, and hear each crystal ring as it lights up. HOW TO PLAY • Tap a mirror to turn it. Every tap is one move. • Guide the light through every crystal to win. • Colours add up, like real light: red + blue = purple, red + green = yellow, all three = white. • A crystal wants its exact colour. Extra light counts as wrong. • Match par for three stars. WHAT'S IN IT • 30 hand-picked levels across three chapters: Dawn, Maze and Spectrum. • Walls, locked mirrors, colour filters and beams that mix. • A new daily puzzle every day, the same for everyone, with streaks. • Endless mode once you finish Spectrum. • Musical crystals: every crystal you light plays a note, and the tune climbs as the board fills. • Unlimited undo, and hints when you are properly stuck. • Light and dark themes, following your system setting. • Colour-blind mode that adds shapes to every coloured piece. • Respects your device's "reduce motion" setting.
