This game has fun ideas but you have to spend real money to really progress through the game. You need them to unlock the never ending locked chests thst you get by clearing land or that your dragons find. The price of things in the store rise over time which makes it harder to buy what you need. I have a pile of 20 eggs I can't hatch because they are hard to get or they are over priced in store. Also the wait time to gain cups and chests are way to long. Skip this game. It's a money grabber.
