Become a cosmic force of nature. Guide a hungry black hole through vibrant nebulas, absorb matching stars to grow, and push your luck with every move! HYPNOTIC ARCADE GAMEPLAY Start as a fragile point of darkness, dodging massive stars that dwarf you, then come back for them once you’ve grown. Match your black hole’s color to nearby stars to absorb them and grow in size and power. But be careful, hit the wrong color, collide with the wrong star, or take on something too big too soon and it’s game over! SOUNDTRACK THAT EVOLVES WITH YOU Experience a dynamic synth-wave soundtrack that grows more intense and layered as your black hole expands. The music responds to your size and progress, creating an immersive audio-visual journey that's impossible to put down! ENDLESS PROGRESSION There's no level cap or endpoint. Your skill alone determines how massive your black hole becomes. Early games focus on small white and yellow dwarfs, but survive long enough and you'll navigate fields of towering red supergiants worth thousands of points each.

Gravity OB1

GRAVITY OB1 turns orbital physics into pure arcade thrill. Sling your ship across a living solar system, ride the pull of planets and black holes, and master gravity itself — because the radar is your only map. THREE GAMES IN ONE - CRUISE — Pure flight. No weapons, no boosters. Just you, gravity, and one perfect slingshot to the target. - COMBAT — Full war. Dodge mines, missiles, and asteroid lasers. Boosters and shields at your side. - ASSAULT — Take the fight to the enemy. Dogfight alien ships with a twin-stick control scheme, lock into orbit around planets, and rain fire on your foes. MASTER GRAVITY Every shot is a puzzle. Planets bend your flight path, black holes swallow the careless, and the sun is always hungry. Learn to read the pull, thread the needle, and let physics carry you home. ORBIT LOCK Fly close to any planet and lock into a stable orbit — circle your target hands-free while your cannons and homing missiles pour fire into it. A gravity-powered gunship run like nothing else on mobile. A FLEET OF SHIPS Unlock 8 distinct ships, from the nimble Needle interceptor to the mighty Bastion battleship. Each flies differently — light and fast, or heavy and armored but harder to pull free of gravity's grip. 100 MISSIONS + SUPER NOVA Ten levels across every mode, each with escalating hazards: moving asteroids, black holes, orbiting worlds, and finally the endless waves of Super Nova. FEATURES - Real gravity physics — no two shots ever feel the same - Three completely different game modes - 8 unlockable ships with unique handling - 8 alien enemy types with distinct behaviors - Homing missiles, cannons, boosters, and shields - A tactical radar you'll learn to live by - Premium hand-crafted art and an original soundtrack Free to play the opening of every mode. Unlock the full campaign once — yours forever. Slingshot in. Master the pull. Clear the system.
