The Ancient Astronomers Event is running until March 1 st and has 2 stages.
Start the event Ancient Astronomers by tapping on the event station:
Since you will only have a very limited time to produce the first 3 items, start only when you have the time to craft 3 items and get the needed items from your farm hands.
The first 3 items are: Moon Fish, Olive Cheese Tart and Emblem Pendant.
You need to send your farm hands to the Observatory to collect the needed items for crafting the Moon Fish, Emblem Pendant and Olive Cheese Tart.
For the Observatory you need to make Telescope and the windmill. This will cost you 100 Coins and 5 Minutes. The observatory needs 1 hour.
After you completed the first item you will get new orders. Try to fulfill as many orders as possible to stay and compete in the leaderboard.
These are the other items which can be ordered:
Mosaic Table – Craft Workstation
Sun Pie – Pastry Oven
Bust of Brutus – Craft Workstation
Fishy Sauce – Dinner Oven
Emblem Pendant – Dollmaking Table
Moon Fish – Stovetop
Eclipse Mash – Dinner Oven
If you are ready to invest real money you can buy these 2 farm hands. Each of them costs 150 keys.
If you achieve to score gold in both stages you will get an additional farm hand, the Sun Shepherd.
