Lagario 3: Órbita

I made Lagario: a free multiplayer browser game where you grow a planet with real gravity. It started in 2018 as a weekend blob game; version 3, Órbita, rebuilds it around real physics.

Every planet carries momentum. Stars and big planets pull with inverse-square gravity, and a dotted line shows where you are falling. Dive past a star to slingshot out at up to about 3× your top speed. Complete an orbit and sweep up its dust belt. Get too close and you burn.

Planets of the same size can't eat each other anymore: they collide. A hard hit knocks off chunks that anyone can devour. Eject mass to thrust like a rocket. Grow big enough and you pull smaller planets toward you.

Play free-for-all in Orbit, or bring the physics into Collapse (a battle royale in a shrinking universe), Teams and Gravity Chaos. There are black holes, comets and wormholes too.

• Real gravity: momentum, orbits, slingshots and a live trajectory line

• Multiplayer through a shared link: no account, no servers (peer-to-peer), up to 16 players per room
