🏖️ Sandbox Mode

What is Sandbox? Sandbox Mode is a creative testing environment with unlimited money ($1 million to start), no need decay, time control, and access to all items in the game - including rares. Perfect for designing lots, testing features, or just having fun without restrictions.

Important: Anything built in Sandbox stays in Sandbox. You cannot transfer creations to the live game, but you can use Sandbox as a blueprint to rebuild your designs.

🚪 Accessing Sandbox

From the XenoSO login screen (without logging in), click the blue "Sandbox Mode" button in the upper left corner. If you're already logged in, just log out to return to the login screen.

💡 Quick Tips

  • Your Sim starts with half-full needs - use the Omni-Argon immediately
  • Time controls work in Sandbox (P/1/2/3 for pause/speed)
  • Save frequently with Ctrl + S
  • Use Sandbox to plan expensive builds and calculate costs before building in live mode
  • Test rare object interactions before buying them in the live game
