All players begin at level 1 with a basic Castle made of wood. As you advance in through the League system, your Castle will transform from wood to stone to gold - becoming bigger and more glorious!
Your Castle will upgrade automatically (if you have fulfilled the necessary requirement) at the end of each week when the Weekly Challenge closes. Note: the Weekly Challenge ends at different times for the different versions of the game.
You can view your Castle's current level, along with the Rank List placement needed for subsequent upgrades and images of future Castles, in the game by clicking on the "My Castle" button and then on the "Upgrade" button.
Castles can NOT be downgraded. Once a Castle reaches a particular level, it will remain at that level until the requirement for the next upgrade is met.
