The objective of Lumen is to light up all the checkpoints in the puzzle by bouncing, coloring, and maneuvering a laser beam through obstacles. Lumen is meant to be picked up quickly, and enjoyed endlessly. There are only 5 simple parts to learn before you can begin playing. Puzzles can be enjoyed leisurely, even put down and resumed later, as there are no timers or scores. Just sit back and relax with Lumen. The full (non-Lite) version of Lumen has access to an online database.
