Read full description

Fly deeper into space than anyone else. Gravity Sling is a one-thumb space arcade built on real orbital physics. Press and hold to burn toward your finger, release to coast. Skim past a planet's gravity well and it whips you forward — that slingshot is free speed, and it is the whole game. SIMPLE TO PLAY, HARD TO MASTER • One control: hold to thrust, release to glide • Hold behind your ship to slow down with reverse thrust • Every metre costs fuel, so plan your burns • Interactive flight school teaches you in seven short lessons A UNIVERSE THAT FIGHTS BACK • Planets, gas giants, ice worlds, lava worlds and magnetic anomalies • Black holes that drag in everything — including bosses — and spaghettify anything that crosses the horizon • White holes that shove you away instead of pulling you in • Space worms and storm rays that hunt you down and swallow you whole • Boss encounters: the Void Leviathan and the Storm Ray match your speed. No escape — bring them down GEAR UP IN THE HANGAR • 10 ships, 10 engine trails, 10 engine flames • Every item has real stats and five upgrade levels • Six permanent upgrade tracks: fuel, hull, thrust, efficiency, magnet, assist • Homing rockets, a five-missile salvo and a ten-second shield • Everything is bought with stars you earn by flying. No paid shortcuts COMPETE AND COME BACK • World and country leaderboards — see the top 20 and exactly where you rank • Rotating daily and weekly missions, plus one big weekly mega mission • Daily rewards with a streak multiplier, and a Star Vault that banks a share of every run • Free account syncs your stars, ships and records across every device PLAYS IN YOUR LANGUAGE English, Türkçe, 简体中文, हिन्दी, Español, العربية Free to play, with ads.
