Planet Hopper
Launch from orbit to orbit with one button, collecting stars as you hop from planet to planet.
Gravity Orbit
Launch a probe from the left edge and let the pull of nearby planets curve it into a wormhole. Each level is a small puzzle, and you only have 3 attempts for the whole game.
Controls
| ← → or ↑ ↓ | Rotate the aim (Left/Up aims higher, Right/Down aims lower) |

| Hold Space, then release | Charge power, then launch |
| P or Esc | Pause / resume |
| R | Restart |
| ▲ ▼ buttons | Rotate the aim |
|---|---|

| Press and hold on the game | Aim at your finger and charge; lift to launch |
| Move the pointer | Aim toward the pointer |

| Press and hold, then release | Charge power, then launch |
On touch screens a control pad appears below the game. You can show or hide it with the Touch pad button above the game.
How to Play
- Press Start Game. The launcher sits on the left edge; the swirling wormhole is your goal.
- Aim with the arrow keys, the ▲ ▼ buttons or by pointing. The angle is shown under the launcher, and a short dotted line previews the first moment of flight.
- Hold Space, LAUNCH or the mouse button to fill the power bar, then release to fire. More power means a faster, straighter shot.
- Planets pull the probe toward them, and the pull is stronger the closer it passes. Touching a planet, leaving the screen or flying for 12 seconds without arriving costs one attempt.
- Reach the wormhole to finish the level. Fly through stars on the way for bonus points. Your previous shot stays on screen as a faint line so you can adjust.
Objective
Clear as many levels as you can with your 3 attempts. Every level completed, every star collected and every level cleared on the first or second try adds to your score.
Difficulty progression
Levels 1 to 10 are hand-designed: level 1 has no planets, levels 2 to 6 use one or two, and levels 7 to 10 use three or four. The wormhole shrinks at levels 4 and 7. From level 11 the levels are generated: they start with 2 planets and add one every two levels up to 5, the wormhole keeps shrinking down to a minimum size, and planets pull up to 50% harder. Every generated level is tested by simulating a grid of launches and is only used if several shots reach the wormhole.
Scoring
| Action | Points |
|---|---|
| Level completed | +100 × level number |
| Cleared on the first attempt | +150 bonus |
| Cleared on the second attempt | +50 bonus |
| Star collected | +50 (stays collected even if that shot fails) |

Tips
- Use the faint line of your last shot. If it passed just above the wormhole, aim a few degrees lower and keep the same power.
- Note the angle shown under the launcher and how long you held the charge. Repeating a shot with a small change is the fastest way to solve a level.
- Low-power shots bend much more than full-power shots because the probe spends longer near each planet. Use full power when you want a nearly straight line.
- Passing close to a planet on purpose can whip the probe around it, but the closer you pass, the more a tiny aiming error matters.
- Stars are optional. With only 3 attempts for the whole game, clearing the level on the first try is worth more than a risky star.
- On a keyboard, tap the arrow keys for small aim changes; holding them turns the launcher steadily.

About Gravity Orbit
Gravity Orbit is a slow-thinking, precise-shooting puzzle game. You never steer the probe after launch, so each shot is decided entirely by angle and power. The planets act as obstacles and as tools at the same time: a planet in the way might be exactly what curves your shot into a wormhole hidden behind it.
The gravity is an arcade rule inspired by the real idea that gravity weakens with distance. Here each planet's pull follows a simple formula and there is no fuel, no orbit mechanics and no scientific accuracy, so treat it as a puzzle rather than a lesson in spaceflight. The attempt limit makes it one of the harder games on the site: three failed shots across the whole run end the game, and your best score is saved locally in your browser.

Frequently Asked Questions
Do I get new attempts on each level?
No. You have 3 attempts for the whole game. Each failed shot uses one, and the game ends when all three are gone. Clearing a level does not restore attempts.
What ends an attempt?
Touching a planet, leaving the screen, or flying for 12 seconds without reaching the wormhole (for example when the probe gets stuck circling a planet).
How long is the aim preview?
The dotted preview shows only the first fraction of a second of flight, including gravity. While you charge, it updates to your current power; otherwise it shows a half-power shot.
Are the generated levels always possible?
Yes. Before a generated level is shown, the game simulates a grid of launch angles and powers and only keeps the layout if several of those shots reach the wormhole. Its stars are placed on one of those working paths.
Is this realistic orbital physics?
No. The game uses a simplified arcade gravity rule so levels are readable and fair. Real spaceflight involves far more factors.
