Place a moon let go and watch it fall into orbit around the planet you just made.

Pocket Galaxy is a 3D gravity sandbox and solar system simulator: you place planets stars and moons and real physics decides what happens next. Nudge one world and the whole galaxy answers.

Free to play with ads; an in-app purchase removes them or there is a separate paid app Pocket Galaxy - Sandbox Game.

What you can do
• Sculpt entire solar systems from a near-infinite variety of worlds
• Tune each planet's gravity size and orbit even give it repulsive gravity
• Reach for cosmic tools: asteroid storms solar rays ice rays and explosions
• Unlock new planet and star types as you experiment
• Discover procedural planets gas giants and glowing stars
• Track your creations and watch life develop in the Planet Journal
• Save load and screenshot your universe to share with friends

The cosmos here is a toy box rather than a lesson. Nurture a world until life begins or smash the lot to particles in open space; a solar system simulator that lets you undo an evening's work in one collision is still doing its job.

Drift through a galaxy of your own making and the sandbox stays patient. No goals no score nothing counting down. The cosmos waits while you decide what a universe should look like and open space is large enough for every answer you try.

Contains ads and an optional in-app purchase to remove them. No account required and it suits all ages.
