Gravix: Gravity Sort Puzzle

Let gravity move the planets. Choose where they land.

Gravix: Gravity Sort is a space-themed physics puzzle game about planning routes and sorting planets. Watch the queue, tap splitters, open gates and guide each spinning planet into the matching bowl. A wrong landing ends the attempt, so every decision counts.

500 PUZZLES ACROSS 10 WORLDS
Start with simple routes in Gravity Basics, then explore worlds with linked switches, automatic spinners, timed gates, color filters, magnets and reverse-gravity fields. Learn new mechanisms as the campaign grows more challenging.

PLAN, TAP AND EARN STARS
Study the route before you drop the planets. Time your taps as they fall, keep an eye on bowl capacities and try to solve each level with fewer moves. Replay completed puzzles to improve your star score.

FOUR OPTIONAL BOOSTERS
• Undo rewinds to before your last tap.
• Hint highlights a useful next move and its timing.
• Freeze pauses falling objects for a few seconds.
• Slow-Mo slows the machine so you have more time to react.

A DAILY GRAVITY CHALLENGE
Return for a puzzle generated for the day, track your streak and collect rewards. Keep working toward achievements as you sort more planets and finish new worlds.

A COSMIC SORTING MACHINE
Glossy rotating planets, glowing chrome rails and matching bowls make the route easy to follow. Each planet type has its own surface design as well as its color. Adjust music, sound effects and vibration, or enable reduced motion.

PLAY AT YOUR OWN PACE
The single-player puzzles work offline and do not require an account. Progress is stored on your device, including supported unfinished attempts, so you can return to your gravity machine later.
