Lumen is a simple and beautiful puzzle game for OS X and iPhone. The objective is to light up checkpoints by bouncing, coloring, and maneuvering a laser beam through obstacles. Although puzzles may seem easy at first sight, they can be quite a challenge. The careful attention to detail and the colorful graphics make Lumen a joy to play.

The desktop version of Lumen allows you to explore board sizes much larger than the standard 7x7. The new puzzle selector allows you to quickly search and preview puzzles. The puzzle editor has been redesigned to make it easier to test a puzzle before submission. If you get too stuck on a puzzle, you can choose to see the solution and then move on to another one of the thousands available.
