Universe Sandbox

Universe Sandbox does not follow a traditional story or campaign. Instead, it places you in the role of a cosmic creator and observer, giving you complete control over the universe itself. You can build entire solar systems, collide planets, ignite or extinguish stars, and witness the laws of physics unfold in real time. Every simulation becomes a unique narrative shaped by your own experiments, whether you're recreating our Solar System, imagining alien worlds, or triggering galaxy-scale catastrophes. As gravity, climate, orbital mechanics, and stellar evolution interact realistically, each choice leads to fascinating and often unpredictable outcomes. Rather than telling a fixed tale, Universe Sandbox invites you to explore the beauty, complexity, and immense power of the cosmos through limitless scientific creativity and discovery.
