PrismShift – Light Beam Puzzle

PrismShift places a 6×6 grid of tiles on a clean white laboratory surface. A laser beam shoots from a source tile and travels in a straight line until it hits something. Mirror tiles on the grid bend the beam 90 degrees when the beam touches them. Prism tiles split a white beam into three coloured streams — red, green, and blue — each continuing in the same direction. Your goal is to get every coloured receiver lit by the matching beam colour. The tiles are fixed to the grid but some of them are movable — swipe a movable tile up, down, left, or right to shift it into an adjacent empty space, exactly like sliding tiles in a puzzle. As you move tiles the beam instantly re-traces its path so you can see the effect in real time. Each level scores you based on how few moves it took to solve, so there is always a reason to think carefully before sliding.
