A little glow. A vast ocean. Your next best score. In LUMA — Into the Blue, guide a glowing jellyfish through sunken ruins. Tap to rise and find your rhythm between ancient stone pillars. Every passage you fully clear earns one point. Three difficulties put your timing to the test: learn the rhythm on Easy, face a gradually faster current on Medium, or take on narrower gaps and a higher pace on Hard. Each difficulty has its own personal best and Game Center leaderboard. Unlock 11 achievements and collect their badges. From your first passage to 1,000 points in a single run, there is always another goal to reach. A small notification celebrates each achievement as you earn it. A short tutorial guides your first dive, and you can skip it at any time. Pause whenever you need to, then ease back in with a 3–2–1 countdown. Glowing coral, deep ocean blue and original music set the scene for your next attempt. Play locally offline without signing in. Connect to Game Center for online leaderboards and achievement syncing. Available in English and German. Includes ads between rounds. No in-app purchases. Ready for another dive?
