Build your own universe from a near infinite variety of planets. Watch your universe evolve & discover new planets, stars, & other cosmic objects. Save your creations.

If you had the power, how would you create the solar system? What planets or stars would you choose? How would you place them in orbit? Are you interested in Astronomy and looking for a powerful yet easy to use 3d simulation sandbox game, to create and simulate a whole new galaxy with realistic physics rules? Then you’ve come to the right place. My Pocket Galaxy, the 3D sandbox game, provides you the ultimate power to explore the infinite space and simulate your own universe where you customise each different planet, gas giant, and star. Destroy on an unimaginable scale.

Create Your Own Universe
Build your own universe, and simulate all the planet orbits in infinite space with this realistic physics sandbox. Customize your entire solar system down to the individual star, planet, and moon. Give your alien planet repulsive gravity or even create a replica of the Earth, your imagination is the limit.

Destroy an entire Solar System
Become the ultimate planet destroyer or solar smasher, in the best galaxy destruction game! Tap in space to unleash a barrage of asteroids on an unsuspecting world. Destroy planets using a solar ray or freeze them with the ice ray.

Realistic Gravity Simulation
See how your pocket universe plays out over time with the in built realistic physics simulator. Observe as your creations flourish or collapse into destruction. Intervene like a god with physics tools to affect the orbit of planets, heat them up, cool them down or explode them!

Explore And Unlock
With endless variations of planets, stars ,and more; you’ll never run out of creative options. Smash planets together and affect planet conditions to unlock new types. Explore how life develops in your solar system through the planet journal.

I really like this game! But if you can just make a little update like if you can put inclination which the orbit of a planet goes up and down and also put farther camera zoom out and when you put a black hole very far away, it doesn’t affect any objects, and lastly, if you could make a button on the settings of a star called the end life button which will make the star end its life, if it is a yellow star, it turns into a white dwarf, if it’s a red giant, it turns into a white dwarf, if it’s a blue giant, it turns into a neutron star or black hole. And add more objects like brown dwarfs (which are failed star or burned up gas giants) red dwarfs (which is a small red star) a protostar (which is not a star or brown dwarf it is a small object with stuff coming out of the top) supergiants (which are huge stars larger then the blue giant) and neutron stars (which are stars WAY smaller than an asteroid and has very strong gravity). And add a button when you place an object and go to its settings were you can change the mass of any objects. And also in the settings of a object can you add how a planet spins.

I will tell you the problems ,

Very hard to use

First, I just wanna point out to make a planet orbit in a cool and Stableway is really hard even when you make a star and click orbit planets still orbit in a really weird way and when you try to make like a black hole system and make a planet really close, its orbit becomes wacky at triple speed it starts becoming like a multiple pointed shape instead of a circle also, I would like you to make less ads every single time you restart our universe no matter even a second after you made it there’s an ad so you should also make less ads and also like you should add supergiant stars they’re just giant stars there’s no orange, giants, or anything. You should also have super giants like blue, super giants and red supergiant you should also make it easier for moons to do, another orbit problem is that whenever you try to make like a comet, you can’t even see how it orbits also when you have a certain amount of planets, stars and moons also count as planets, I think you should have like a number that says certain amount of moon certain amount and stars so basically, it’s hard to use the game and has a lot of features that are bad but it’s cool that sometimes you can make things on your own like I figured out how to make a binary system but still this game limits you a lot

Glitches... and ideas

ima start with glitches, so #1 when I collide many stars it create those small black stars! (If it’s a black hole then well..) #2 same with #1, BUT it doesn’t collide stars to make the glitch. It just GETS A SPACE STATION RANDOMLY. Even without planets or stars. #3 when I collide with many stars, it forms that black thing, right? But there’s a chance that ITS FROM THE TITLE SCREEN, #4 when I place a planet so far away, the arrow thingy for the planets/stars just wiggles! #5 my brother was distracting me, messing with me (he was not messing around with the game, then after that, EVERY star in a solar system JUST dissiperre! #6 when I create a big big galaxy, and restart the app, in the galaxy, IT WILL not give you more planets by watching ads. I had 24 or 25 planets/stars there. So is 25 PLANETS is the maximum planet without the full version? moving on to ideas... #1 fix those glitches
#2 maybe when a planet is hatible and has amimals and people, maybe add buildings on the planet visible from space! #3 make a stable orbit thing so the planet doesn’t go colder and hotter!
#4 infinity planets! I really suggested that. #5 undo and redo! #6 make rockets in a hatible planet! They could go to anywhere! #7 add an asteroid belt! That’s probably all I could suggest. Bye
