Tower Islands are live events that appear in the middle of your City. Tap it to enter.
Use Tower Coins to pull the lever and determine your number of moves (one, two, or three). Work your way up the Tower while earning rewards along the way. Catapults can help you jump from one row to another; look closely at the arrows to indicate their direction.
Reach the top of the Tower to obtain an exclusive dragon or collect all available puzzle pieces of a dragon along the way to obtain other dragons.
Tower Coins can be collected by performing various actions in your City, such as collecting Gold & Food, feeding your dragons, winning League battles, breeding & hatching dragons, and watching videos on Dragon TV.
