Green Gems are a special resource used in advanced gameplay features.
Below you can find all the ways to unlock and collect Green Gems.
How to get Green Gems
- Complete certain Helping Hand levels for Locals to earn Green Gems.
- Use the Green Gem Factory and Green Gem Drill to convert other resources into Green Gems (details below).
- You can also get Green Gems from Cards on the map (in the narrative, they are labeled simply as “Card”).
Green Gem Factory
The Green Gem Factory unlocks after Level 40, once you have collected all required yellow Workers from Levels 31-40.
To unlock it, collect all yellow Workers from Levels 31-40.
After it is unlocked, you can use it to convert extra resources into Green Gems.
Green Gem Drill
Green Gem Factory = Green Gem Drill. Once you have built the factory, you can spend your extra resources to drill for Green Gems.
- Use extra Pink Gems, Orange Bricks, and Blue Hats to drill for Green Gems.
- This is the easiest way to collect Green Gems.
Quick tips
- If you can’t use the Green Gem Factory yet, focus on Helping Hand levels that reward Green Gems.
- Since Green Gems carry over between Cities, it’s worth saving them for Monuments you really want to build.
