Where is this wheel?

Unlocks in the task bar when you collect your first coin.

First coin comes from Egg Nog Bar. Egg Nog Bar is first prize at like 250 gift cards. It is an instant building, and has a 24 hour pay out of a single coin. I sped up my pay out to try out the wheel.

After you get first coin, you can buy them for donuts in the premium menu. I think it's 10 or 15 for a single coin, and like 25 donuts for 3 coins.
