The Castle is the key to your town. If it falls in battle, you are defeated. You can upgrade your Castle to unlock new and improved Defenses, as well as to hold more Gold. Higher level Castles require your opponent to score more points for a 3 star victory. Once your Castle reaches higher levels, both your Castle and Gold Wheels will possesses the magic to move further west across your town. The Castle is home to our magical letter crafting Elves, so make sure to refill your Tile Bag here before heading to battle.
