Mystrons are a very useful currency in the game. There are 4 types of Mystrons in the game and each Mystron can be acquired from different places.
If you’re lucky, you can get Green Mystrons from:
  • Calendar
  • Wheel of Fortune
  • Fishing
  • Cleaning decoration

Yellow Mystrons can be obtained from:
  • Weekly Activity
  • Special Discount Decoration

Blue Mystrons can be obtained from:
  • Order Board (only if you have finished the first round of Order Board and have already obtained the Gasoline Sheep)

Purple Mystrons can be obtained from:
  • Farm Beauty Contest


Mystrons can be used in the Mystery Store to buy special items, as can be seen in the picture below. The Mystery Store can be accessed from the Store in your game. It's located at the top left corner of the Store window. At the top of the screen on the right side, you can see how many Mystrons you currently have.
The special items change every 24 hours and you can see a timer which indicates when the special items will change. The RC is the only item that will always be available in the Green Mystrons tab, but note that the price for the RC changes every day.
