Gravity golf physics puzzle

How to play ORBIT

ORBIT is a free daily physics puzzle: golf, but the course is a solar system. You drag to launch a probe and let the real gravity of the planets curve its path into the beacon. There is never a straight-shot answer, so every hole is a small orbital-mechanics puzzle you solve with one careful launch at a time.

Play ORBIT

How to play

  1. 1Drag anywhere on the screen and release to launch your probe.
  2. 2Planets pull the probe with real gravity - use them to bend your shot around obstacles.
  3. 3Release before the aiming ring closes, or the shot is wasted.
  4. 4Reach the beacon to finish the hole, and grab the bonus star on the way for extra credit.
  5. 5Complete every hole in as few launches as you can.

Tips and strategy

  • You cannot win with a straight line. Every hole is designed to need a slingshot around a planet.
  • Watch the dotted preview arc as you aim to see roughly where the probe will travel.
  • Fuel is limited per hole, so a few smart launches beat spraying shots.
  • Skim close to a planet for a tight gravity turn, but not so close that you crash into it.

Frequently asked questions

Is ORBIT free?

Yes, ORBIT is free to play in your browser with no download and no account needed.

Why can't I hit the beacon directly?

Every ORBIT hole is validated so that a straight shot never works - you always have to use a planet's gravity to curve the probe. That is the puzzle.

What is endless mode?

Endless mode is a fuel roguelite: each hole you clear refills some fuel, the systems get denser, and your run ends when you run out. Chase your best streak of holes.
