EcoClicker is a game where you have to save earth from global warming by planting trees. Please post in the forum if you experience any issue or for any feedback. Thank you for playing!

How to play

  1. Click the big green button to grow some trees.
  2. Click the big yellow button to chop some trees and get some gold
  3. Hire workers to help you grow and chop trees (Use Alt+Click to bulk buy and sell workers)
  4. Adopt policies and research new techs to improve your yield
  5. Make sure you keep temperature anomaly between -3°C and +3.5°C or the game would be over...
