Make room for the next launch. Nebula Sort is a colour-sorting puzzle set among the stars. Guide capsules to matching ships, clear blocked routes and turn a careful move into a satisfying chain of launches. Every capsule points in a direction. Find a clear path and tap to launch it. Capsules that cannot board the current ship wait in a limited bay, so the order of your moves matters. Keep enough room for the next arrival. A LITTLE PLANNING. A BIG CHAIN REACTION. Matching capsules can pull their neighbours along. Nebula clouds hide capsules until you free a neighbouring space. Look beyond the next tap and discover how the board fits together. • 200 sectors to solve, with no countdown in ordinary play. • Chain launches and nebula clouds that change your next decision. • Five boosters: undo, hint, magnet, shuffle and two extra bay slots. • Stars and coins to earn through play. • Game Center leaderboards for stars and cleared sectors. • Six cosmic backdrops, original ambient music and responsive sound effects. • Distinct capsule symbols alongside colours. • 14 languages, with separate controls for music, effects and haptics. Take your time. Read the routes. Send the next ship on its way. Includes optional in-app purchases.
