Prism: Mirror Puzzle

Bend light, mix colour, and turn every board into stained glass.

Prism is a calm puzzle about light. Coloured beams shine in from lamps at the edge of the board. Tap a mirror to turn it, steer each beam across the board, and light every crystal with exactly its colour. When the last one glows, the whole board freezes into stained glass.

The twist is colour mixing. Send red and blue into the same crystal and it glows purple. Red and green make yellow; all three make white. Some crystals can only be solved by crossing beams on purpose, and one stray beam can spoil a crystal you already had right.

There's no timer and no way to lose. Every level has exactly one solution, so there's always a clean "aha" waiting.
