The 10-year anniversary of Universe Sandbox’s Early Access launch on Steam is this Sunday, August 24, 2025!
To celebrate this milestone, Universe Sandbox will be on sale now until August 28.
Over the last 10 years, we’ve added so many new features to make Universe Sandbox better than ever, from simulating liquids and gases flowing over planet surfaces and lasers in 2019, to realistically simulating planet atmospheres and accurately terraforming planets in 2023, and our major graphics update just a few months ago.
And we have so much planned. We’re currently working on
Improving collisions with more realistic friction and craters and simulating atmospheric drag, which allows meteors to burn up in the atmosphere.
Adding basic life simulation where life grows, dies, and can be eaten.
Bringing Universe Sandbox to phones and tablets (iOS & Android).
Our long-term goals stretch years into the future and include
Detailed planet surface so you can fly over mountains and through canyons.
More planet customization with custom maps or images, like a picture of your dog.
Colliding everyday objects, including simple shapes like dice and complex shapes like spacecraft, according to their unique forms instead of as spheres, also called rigid-body physics.
And so much more!

We’re incredibly grateful that we’ve been able to continue developing and improving Universe Sandbox over the last decade, and we're humbled by the ongoing support of our community. Thank you all for giving us the opportunity to make this crazy game.
We’re proud of what we’ve accomplished since Universe Sandbox was first released on Steam in Early Access 10 years ago, and we’re so excited about everything that’s still to come.
