I saw your post about not having the Wheel. I too had this problem.
Usually it's because you're playing the Halloween version.
There is an updated version of the game, though on a new, free app. The Birthday version.
Not only will you get all the current events but there is extensive dragons, habits etc. not on other version.
One last note. There are a few things, such as reward statues for
10 Epic dragons you will have to revert to Halloween version to get.
Best of luck!
