I love this game saving the sweet little Dragons but the adds are a joke with length and frequency! Plus they want you to make in App purchases to play buying tools to assist you and to empty your piggy bank of accrued coins! You could get yourself into financial trouble with this, you can of course play it without buying anything but they frequently push you purchase which I just ignore. I also put my phone down at the end of the game while the adds play and do something else! Beware!
