Lumen: Light & Mirrors

Place a mirror. Bend the beam. Light the crystal. Explore an optics workshop, a prism laboratory, an observatory, a light tower and a conservatory. Each building has its own atmosphere, with brass instruments, stone floors and rooms to discover. Start on a small board, learn how reflections work and move on to larger puzzles. Walls block your path, mirrors change its direction, and every placement matters. Higher up, the light plays by new rules. In the observatory, lenses change its color and colored glass lets only the matching color through. In the light tower, portals carry the beam across the board and a splitter sends it two ways at once. In the conservatory, a prism splits the light into red and blue, and a dark crystal must stay dark. Take your time in most rooms. In others, the light can travel only so far, or slowly burns down while you find a route. Catch coins with the beam and spend them on hints when you need a hand. Return to completed rooms to try another path and earn more stars. Tap to place and turn a mirror. Hold it to remove it. Simple controls leave room for the puzzle. The optics workshop is free to play. Lumen Unlimited, a one-time purchase, opens the prism laboratory, the observatory, the light tower, the conservatory and every building still to come. If you played before this update, every building you reached stays open. Every building you finish offers walks: fresh puzzles made on the spot from that building's pieces. Three a day for free, or as many as you like with Lumen Unlimited. Play offline on your phone or tablet. Available in English, Polish, Ukrainian and Russian. No ads and no account required.
