EDIT: All the fun has gone out of rhis game now. The ads cause relentless crashing and back to the start up screen. Today I have been trying for over an hour just to nurture the egg. The challenge prize is becoming impossible to achieve due to the adverts. The side speed game is too stressful and costs a fortune in diamonds unless you have a very fast device. I never have enough time by the fourth stage. On the verge of quitting after four years. So sad when I used to love the game so much.
