Lightsmith: Prism Puzzles

A beam of white light crosses the board. Your job is to get it where it needs to go — and in the right colour.

Place mirrors to turn it. Split it with a half-silvered glass. Push it through a prism and watch white come apart into red, green and blue. Then put those colours back together: red and green make yellow, green and blue make cyan, and a target only lights when it receives exactly its own colour. White light reaching a red target does nothing at all.

Sixty hand-built levels, each one a small idea rather than the last one made larger.

WHAT YOU GET
• 60 levels across six sets — mirrors, splitters, prisms, filters, and everything at once
• A clean, quiet board: no timer, no lives, no energy to wait for
• Undo as far back as you like, restart whenever, and skip any level that has you stuck
• Play the first ten free; one payment opens the rest and removes the ads for good
• Works entirely offline

NO CLOCK, NO PRESSURE
There is no way to lose. Nothing expires while you are away, nothing is taken from you for thinking too long, and no level is ever locked behind watching a video. Put it down mid-puzzle and it will be exactly where you left it.

Every level has been checked to be solvable — the game is a puzzle, not a guess.
