My son has been playing since end of September-beginning of October and has gotten them every single morning. I have been playing since July and haven't gotten a single one! For me, I think it is great that he gets them every day since I will not allow him to buy diamonds and he has learned how to save his diamonds for things he wants. He is only six years old so I am grateful. I must say that I am a little bit jealous! Lol.
From what it looks like, they must have been testing this for a while then. I wonder what kind of stats they are looking for. :confused:
