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.
