Pocket Universe - 3D Sandbox

If you had the power, how would you create the solar system? What would be the size of each planet or star? And how would you place them in orbit? If you are interested in Astronomy and looking for a powerful yet easy to use 3D universe sandbox app to create and simulate a whole new galaxy with realistic physics and gravity rules, then you’ve come to the right place. Pocket Universe, the 3D gravity sandbox game, provides you the ultimate power to explore the infinite space and simulate your own space full of different planets, gas giants, and stars. In this gravity simulator app, you get to customize literally any aspect of these particles to simulate and design your very own pocket universe sandbox. Once you are satisfied with your customized solar system (or any other combination of particles, planets, and stars), you get to easily add it to your collection, take a screenshot and share it with the world. Pocket Universe comes with a clean and neat design and the 3D simulation is so smooth that you won’t feel any difficulties or lags when bombarding your planets, or applying any condition to them. And make sure not to take the realistic gravity lensing effect as granted when looking at a black hole. It’s just fascinating. Is Pocket Universe Easy to Use? Is this 3D universe sandbox with realistic physics simulation powerful enough to create and design different planets, gas giants and stars? The answer is a BIG yes! But are the simulation tools easy to use? The answer is even a BIGGER yes! The user interface is so friendly, that you’ll get used to it after going through the step-by-step tutorial and trying available tools for a few times. After that, you just need to use your imagination and be creative to form some unique pocket universes with gravity simulator based on physics rules. If you are going to redesign our lovely solar system in our galaxy, you’ll have access to all the planets (mars, moon, earth, mercury etc …) and you have the power to unlock new worlds by meeting the right conditions, colliding with the right objects, and altering mass and sea level while keeping the temperature stable. To smash stuff together and create new planets, make sure to crash the right ones together. Tip: To raise the sea level, hit a planet with ice meteors, and use rock meteors to lower the sea level. Pocket Universe 3D Sandbox Main Features at a Glance: • Wonderful 3D graphics with smooth universe simulator • Super user-friendly interface with easy to learn gameplay • Step-by-step and detailed tutorial • Huge variety of particles, procedural planets, gas giants and stars • Ultimate customization options for your creations • 3D Gravity simulator with realistic physics rules • Create Solar System with the tiniest details • Take screenshots from your pocket universe and share it with family and friends • Unlock new achievements • Interactive journal to track your creations • Save and Load simulated universes • NO ADS and NO in-app purchase items So, Pocket Universe offers everything you should expect from such 3D gravity and Universe Sandbox games and it even sets the bar to a higher level by offering smooth particle simulator, realistic physics rules, user-friendly interface, a wide range of different particles, planets and stars, and a lot more. No matter you are serious in Astronomy stuff or you just want to have fun creating some beautiful infinite universes, we’ve got you covered. You just need to take your time, select from wide range of stunning particles, stars, and planets, specify their positions and how they should rotate, and last but not the least decide which planets should collide to destroy and create new worlds. Download Pocket Universe and let us know about any bugs, feature requests or any other suggestions. Stay tuned for whole new features, including repulsive gravity, fully 3D physics on different orbital planes, the option to view from the surface of the world and expanding on the life aspect of the game.

Player estimates

Nobody publishes how many people play Pocket Universe - 3D Sandbox, so these figures are modelled from the public counts on App Store, Twitch. Each count stands in a roughly known ratio to a population — one Play rating per ~45 players, one Steam review per ~35 owners — and the estimates below combine those readings, weighted by how much each source can be trusted to speak for the whole game. Read the range as the answer and the headline as its middle.

Frequently asked questions

How many people play Pocket Universe - 3D Sandbox?

We estimate that about 600,000 people have played Pocket Universe - 3D Sandbox — plausibly between 300K and 1.2M. Around 30,000 of them play on a given day, in a range of 3K and 180K. Both figures are modelled from public counts on App Store and Twitch rather than published by the developer, so read them as a scale rather than as a headcount.

Is Pocket Universe - 3D Sandbox still active?

Yes. Pocket Universe - 3D Sandbox is holding steady — it measured within a percent of where it was a week ago. We recheck every source daily, and the charts on this page show each platform's readings over time.

How are the Pocket Universe - 3D Sandbox player estimates worked out?

Nobody publishes player counts for mobile games, so we infer them. Each public count we can read is converted into a population using a documented ratio — roughly one Google Play rating per 45 people who played, one Steam review per 35 owners, one Discord member per 40 players — and the live counts (Steam concurrents, members online, Twitch viewers) are converted the same way into a daily figure. Those separate estimates are then averaged in proportion to how much each source can be trusted, which is why sources that disagree widen the published range instead of cancelling out. This page is built on 2 readings taken since August 8, 2026.

When was Pocket Universe - 3D Sandbox released?

Pocket Universe - 3D Sandbox was released on April 14, 2017 for iOS.
