## What is Pocket Galaxy?

Build your own universe, then rule it like a god.

Pocket Galaxy is a 3D gravity sandbox where realistic space physics meet total creative freedom. Spawn planets, stars and gas giants, place them in orbit, and watch a living solar system come to life. Then play god with it: heat worlds until they glow, freeze them solid, explode them, or smash them together in stunning destruction.

Often called one of the best universe sandboxes on mobile, it's part relaxing toy, part hands-on physics playground. No levels, no timers, no pressure, just infinite space and your imagination.

WHAT YOU CAN DO
• Build a universe from a huge variety of procedural planets, stars and gas giants
• Simulate realistic gravity and orbital motion in an open 3D sandbox
• Act like a god: heat, cool, explode and smash planets to see what happens
• Unlock new planet types by changing conditions across your solar system
• Follow the planet journal to see how life develops on the worlds you make
• Enjoy rich particles, atmospheres and destruction effects
• Capture and share screenshots of your universe
• Save and load your galaxies anytime

RELAX, CREATE, DESTROY
Nudge an orbit and let gravity take over, engineer a perfectly balanced system, or wipe it all out in a single cosmic collision. The sandbox is entirely yours.

PREMIUM AND AD-FREE
This is the full paid version: no ads, no in-app purchases, no interruptions. Buy once and own the complete sandbox.

If you had the power, how would you build the cosmos? Download Pocket Galaxy and find out.

### 5/5 — The Closest Thing to Universe Sandbox On Mobile [Currently]

*2026-08-09, version 1.8.1*

I’ve been playing his game for like 3-6 years.. and for those 3-6 years this is one of the best mobile games I ever played. I like where you can unlock different planets By doing a specific task. Being able to collide stars and planets is satisfying. And the game is overall just fun. Especially if you have nothing to do If you’re on something like a roadtrip or something since this game Doesn’t require internet. It’s a amazing game that nearly anyone can enjoy.

### 5/5 — I like this it’s just like solar smash

*2026-08-09, version 1.8.1*

It’s super fun and the ways to make it better is no ads, life designs rockets on its own, and more achievements,
