Each tile has a coordinate that can be used for strategic purposes. Tapping any tile on the Map screen will show its details. Going to the Profile screen for you or other players will show the coordinates of the home castle.
Tapping the Move Point icon will bring out the map navigation menu. Adding in the coordinates in the Set Coords fields and tapping Jump will take you there.
Coordinates can be saved for referring later. Tap the tile on the Map screen that you wish to save, and tap Save Coords to label and save the coordinates. This information is stored and can be deleted from the Move Point menu.
