Lumi Cross

Lumi Cross is a glowing logic puzzle about bending light. Every level gives you one or more light sources and a set of crystals that must be lit with exactly the right color. Your job is to place and rotate optical pieces on the grid so each beam travels the perfect path.

It starts gentle and grows into clever, satisfying brain teasers. Drop a mirror to turn a beam, split a ray in two, or send white light through a prism to scatter it into red, green and blue. Color filters keep only the shade you need, and hidden portals warp your beam across the board. Mix beams together to create new colors and solve puzzles that look impossible at first glance.

WHAT YOU CAN DO
Guide colored light from sources into matching crystals.
Place mirrors to reflect beams ninety degrees.
Use splitters to send a beam two ways at once.
Drop a prism to break white light into its colors.
Apply red, green and blue filters to shape each ray.
Send light through portals that link distant tiles.
Solve every board in as few moves as you can to earn three stars.
