How to Play Nebula Sandbox

Learning how to play Nebula Sandbox is incredibly intuitive thanks to its mobile-friendly touch and mouse controls. Start by using the holographic UI panel to select your celestial bodies, ranging from tiny terrestrial planets to massive gas giants and black holes. Click or tap to place them into the endless dark void. To set a planet in motion, simply click, drag, and swipe to apply orbital momentum. You'll instantly see a visual blue trajectory line guiding its path. You can easily drag and rotate your camera view to watch the cosmic ballet unfold from any angle. If you want to speed things up, adjust the time flow slider to watch centuries pass in seconds. Don't forget to experiment with the chaos tools to trigger spectacular meteor showers or force a star into a massive supernova explosion.

Tips & Tricks for Nebula Sandbox

Mastering the universe takes a bit of practice. First, pay attention to the Roche limit when placing moons near massive planets; if they get too close, gravity will tear them apart. Second, use the time flow slider carefully. Pause the game when plotting complex orbits to avoid accidental collisions. Third, for a stable solar system, start with a heavy central star and give your planets a strong, steady swipe to establish a circular orbit. Finally, don't be afraid to use the cinematic camera mode to capture the perfect view of your planetary destruction.
