Your goal is to make a habitable planet by adding enough Water, Atmosphere and Clouds to reach a global average temperature of about 15°C (59°F). You can mix and match, add or remove.

  • Click an item from the right side (red panel) to add that element
  • Click an item in the left to remove that element
  • HINT You must put at least 3 clouds by the planet!!
After each click, it will take a few seconds for the planet to reach a stable, balanced temperature.
