Orbit

Small bodies collide, drop by drop, until a star is born.

Orbit is a physics-based merge game. Drop a small body into the jar, and when two matching sizes touch, they merge into the next size up — real gravity, real bouncing, real collisions, not just numbers ticking over.

How it plays

Aim by moving your finger or cursor above the jar, then release to drop. Watch the chain reaction as matching bodies collide and grow: Dust → Pebble → Rock → Moonlet → Moon → Planetoid → Planet → Gas Giant → Star → Supernova.

Keep the stack below the line. Let it settle too high for too long, and the jar overflows.

No numbers to read, no rules to memorize — if you can drop something and watch two things become one bigger thing, you already know how to play.
