Orbit.io
Grow a tiny planet in a glowing star system. Pull in asteroids with gravity, escape bigger worlds, shield yourself with moons and launch them at rivals.
Orbit.io is a space io game where you play a tiny glowing planet in a crowded star system. Your gravity well pulls nearby asteroids into a spiral until they crash into you and add to your mass, so growing feels smooth and satisfying. A system full of named AI planets is doing the same, and gravity cuts both ways: drift into the well of a much bigger world and it starts dragging you in, while you thrust to escape before it swallows you whole.
Moons are the twist. Every 45 mass earns a moon, up to four, which circle your planet and regrow over time. If a bigger planet catches you, a moon takes the hit and flings you clear instead. You can also launch a moon as a projectile to chip mass off a rival, scattering asteroids you can then pull in. Golden comets streak across the map and are worth a big chunk of mass if you can catch them in your gravity.
Rounds last three minutes and the biggest planet at the end wins and climbs a league, where rivals are more numerous and smarter. Coins buy Gravity Core, Thrusters and Moon Forge upgrades. Your score is the peak mass you reached. It suits players who like growth games with a little physics and timing. Tip: keep at least one moon in reserve before you hunt.
How to play
Drift near asteroids so your gravity pulls them in and adds mass. Planets at least 20% bigger than you pull you toward them and absorb you on contact, while you can absorb planets that much smaller than you. Every 45 mass gives you a moon (up to four): a moon blocks one absorption and pushes you away, or you can launch it to knock mass off a rival. Catch golden comets for a big boost. If you are absorbed, you respawn as a small planet. The biggest planet when the timer ends wins; your score is your peak mass.
