Swingby: Gravity Orbit Puzzle

Pull back, let go and let gravity bend your orbit around planets to the Light Gate. 200 stages of 10 to 30 seconds, plus a new Daily Orbit every day.

Pull back, let go, and watch gravity take over.

Swingby is a calm physics puzzle built on one simple idea: your little probe never flies straight. Every planet pulls on it and bends its path into a gravity orbit. Read the orbit, skim past a planet to change course, and guide the probe into the Light Gate. Collect all three star shards on the way for a perfect run.

WHY YOU'LL ENJOY IT

• Learn it in seconds: one gesture, pull back and release. A finger guide shows newcomers exactly how to play.
• Made for short breaks: stages take 10 to 30 seconds, and a retry is instant.
• That "it worked!" moment when your shot curves around a planet and slides into the gate.
• Play at your own pace: take as long as you like to line up each shot.
• Something new to master every time a sector opens.

HOW TO PLAY

• Drag anywhere on the screen to aim, then release to launch.
• Planets, moons and black holes pull on your probe. Read the gravity orbit and swing around obstacles.
• Reach the Light Gate to clear the stage. Star shards on the way earn up to 3 stars.
• Stuck? A hint shows you more of the orbit.

10 SECTORS, 200 GRAVITY ORBIT PUZZLES Each sector adds one new mechanic and mixes it with everything you have learned:

• First Sector: planets, asteroids, orbiting moons and black holes
• Wormholes: dive into one mouth and fly out of the other
• Repelling stars that push your probe away
• Boost rings that turn and speed up your shot
• Mirrors that bounce your path
• Solar wind that drifts every orbit
• Pulsing stars whose gravity switches on and off
• Drifting asteroids that sweep back and forth
• Keys you must collect before the gate opens
• The Far Sector: a moving gate and every mechanic combined Every stage is checked to be solvable, so there is always a way through. New sectors open as you collect stars.

DAILY CHALLENGES

• Daily Orbit: one new stage every day, the same for every player in the world. Set your best time, check the daily leaderboard, and keep your streak going.
• Daily Missions: three small goals each day, from easy to hard. Every mission you complete earns a medal.
• Medals unlock new probe colors. Turn on notifications if you'd like a reminder when a new orbit arrives.

ENDLESS MODE

• Endless NORMAL: start with 3 probes and see how many stages you can clear in a row. A 3-star finish wins a probe back.
• Endless HARD: very tough stages back to back, with no hints.
• Stop at any time and continue your run later.

COSMIC ATLAS Every celestial body you meet is recorded in the Cosmic Atlas, with an illustration, the real science behind it, and how it behaves in the game. Learn a little astronomy while you play.
