About the game
Prism Path is a laser puzzle about colour. A lamp shines white light across the board, and you tap mirrors and prisms to turn them until every target ring glows in exactly the colour it asks for.
The light behaves like real light, just simplified. A prism splits white into red, green and blue, each leaving through its own side. Coloured glass tints whatever passes through it. When two beams meet in a ring they add up, so red plus blue makes magenta and all three make white again. A ring that gets the wrong mix stays unhappy. The first four levels teach one idea each, followed by 20 tougher boards, all checked by a solver. Fewer taps earn more stars.
