What are the Winterfest Generators?

These unique Mysterious Island locations are on their own islands to the north of the main body of land. They do not require any Mysterious Island Moves to get to them, but you cannot collect the chests on the island until you unlock them.

These locations (we think)* DO NOT require Mysterious Island Moves to get to, just click on the highlighted locations to unlock and start building them!

*They did not require moves to get to them during SummerFest.

What is the Total Amount of Resources That Can be Earned from the Winterfest Generators?

Based on what we know about when each Winterfest Generator will go live, and how long each resource well "refresh," we can do the math on how much total resources can be earned!

We can assume each Winterfest Generator will go live at 2am UTC on the applicable date, and last until the end of Winterfest at 2:00 AM UTC on January 1, 2026.

We will assume they will be full upgraded as soon as they go live:

Winterfest Baubles

December 21st

Total: 198,000

Titan Skin Stones

December 21st

Total: 440,000

Large Skin Stone Chests
