Hi Sherry! Regarding the Clay Hut,
Click to reveal..
this one is an easy puzzle; it just requires some hard labor. In Crafting Hut, craft some Clay Bricks using Fire and Clay (Water and Red Earth). This will require Crafting Technology Level 1. Once 12 Clay Bricks are crafted, send a Master Builder who is also a Trainee Gatherer to take the Clay Bricks to the hut and start repairing. This will require Construction Technology Level 3 and Crafting Technology Level 2 to complete. Repeat this as many times as needed to finish that hut.


Also, the Big Fish version (and other paid versions of the game) don't have the option of in-app purchases, but the Lavastone Generator was provided free to these versions to balance the currency. You can also earn Lavastones through random events in the game and exploring volcanic cracks!
