Dragon City is a game on Facebook with the main objectives of Breeding, Raising, Training, and Selling exotic Dragons. One thing that sets this apart from other games on Facebook, is the fact that this game does not use any from of ‘energy points’ that most facebook games use, which take time and/or money. Another nice feature in the game are the Gems. You can buy them with real money, like in most games, but it is also fairly easy to earn them for free through a variety of methods, e.g. winning Tournaments with your Dragons. If you’re new to the game or lost in some point, start (over) with the Basics to master the game.
