PRISM: Laser Logic Puzzle

Turn a mirror and the light finds a new path. Guide the beam through every gem, then into the exit. There is always exactly one true answer. PRISM is a quiet logic puzzle made of light and mirrors. Tap a mirror to flip it between "/" and "\", route the laser through every glowing gem, and land it in the exit to win. The beam redraws instantly with every tap, so you can test ideas and watch them play out. Decoy mirrors that aren't part of the solution create convincing wrong paths, so tapping around won't get you there. PLAY WITH PEACE OF MIND - Free to start.

FROM THE DEVELOPER Hi, I'm TORANKIRITE. I wanted a calm place to use my head, with no luck and no noise. I hope the quiet click of the light lining up becomes a small, good part of your day.
