Pocket Galaxy: Cosmos Sandbox

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

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 take it apart: heat worlds until they glow, freeze them solid, explode them, or smash two together.

No levels, no timers, no pressure. The sandbox is the whole game, and nothing in it is on rails.

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
• Reach for cosmic tools: asteroid storms, solar rays, ice rays and explosions
• Tune each planet's gravity, size and orbit, even give it repulsive gravity
• Unlock new planet and star types as you experiment
• Nurture a world until life begins, and follow it in the Planet Journal
• Capture and share screenshots of your universe
• Save and load your galaxies anytime

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