Bend the light.
Solve the dark.
Guide a beam through mirrors, prisms, filters and portals until every target glows in the right colour. It starts gently — and then it really makes you think.

Why players stay
A real difficulty curve
Pieces scattered across the board, decoys you don't need and two beams that must never touch. Every tenth level is a Trial.
Light that mixes
Red, green and blue combine into new colours — and a target only lights up in exactly the right one.
Something new every day
A daily puzzle, three missions, a 7-day reward calendar and a weekly star challenge.
Make it yours
Unlock beam themes by levelling up, with lumens or in the store. Themes change the scene, never the puzzle.
Zen mode
Endless relaxing puzzles when you just want to unwind.
Fair to free players
Every level can be finished without paying. Hints are also available through optional short videos.
