NBody Gravitation tests your puzzle-solving skills by placing celestial bodies and guiding their orbits towards specific targets. Experience the intricacies of gravitational pull in this engaging, physics-based challenge from developer Sean Frett.
About this game
Click and drag to place asteroids, planets, and stars, then send them flying into the matching targets in a physics-based puzzle game where everything attracts everything. The levels start simple, but ramp up to include several moving parts and tricky solutions. You'll need to plan your placements carefully in order to win!
An N-body gravity system where everything can move if something near it is heavy enough, or if something crashes into it. These puzzles are firmly grounded in real orbital mechanics!
(Aside from the targets. They don't move. Most of them don't, anyway.)
Exotic matter: It has negative mass, which means it pushes things away instead of attracting them. It's still attracted to normal matter, though.

Version 1.3 Released!
I'm back! We've got a new update dropping today! This episode's not black or white, it's sort of in... The Gradient. Full Change List: Added force zones, or gravitational gradients, or whatever I feel like calling them this week. If you put something in them, it gets pushed in one direction. They may be wacky and conservation-law-defying, but they're still gravity. They'll accelerate a giant iron sphere just as much as a speck of dust. Added 20 new levels using the new mechanic and exploring its many uses. We've got 140 levels now!Read full article on Community Announcements (smf0x10)AnnouncementsOfficial
Version 1.2 Released!
Introducing The Zone of Time! In this sixth episode on the level select screen, you'll need to keep the balls in the target zones for long enough to trigger them, or shoot through the bad target zones fast enough to avoid triggering them. It's all about timing. Hence the name. Full change list: The aforementioned target zones 20 new levels, bringing the total to 120! The version number is now 1.2Read full article on Community Announcements (smf0x10)AnnouncementsOfficial
Version 1.1 Released!
Version 1.1 of NBody Gravitation has been released! This update contains a new episode with 20 more levels, bringing the total up into the triple digits. Additions: A new episode: The Target Mine! Back in the olden days, targets were all stationary and didn't react to gravity at all. Our new targetsteroids fix that, and we got 20 new levels out of this mechanic. I thought the same 60-second loop might get a bit old after 100 levels, so this update also contains new in-level music, set to play on episodes 2 and 5. It has a trombone. Changes: The title screen was changed to say "NBody Gravitation" instead of simply "NBody". Originally, the game's name was just "NBody", but this was changed in the last few days before version 1.0 released, after all the marketing materials were finished. I found out that an unrelated game called "n-body", with a hyphen, already exists on Steam, and I wanted to avoid confusion. Antimatter star balls now properly invert their colors instead of turning gray. The antimatter annihilation effect now has a purplish tint.Read full article on Community Announcements (smf0x10)AnnouncementsOfficial
NBody has been released!
Well, I did it. I made another game. As the title, subtitle, and summary said, it released today. NBody is a puzzle game about gravity. Plenty of other people have made n-body gravity sandboxes, but this is a full-fledged quasi-educational puzzle game. It's got 80 levels at launch, so expect to spend at least a few hours with it!Read full article on Community Announcements (smf0x10)
