The world map shows you the castles of other players and your own troop movements.
World map icons
The pictures on the world map show you the upgrade level of another player’s castle.
If you hover the mouse over a castle, you will see that player’s player level, honor, and alliance. A green banner indicates members of your own alliance, a yellow banner indicates members of a friendly alliance.
Arrows on the world map represent troop movements. You can see a troop’s remaining travel time by clicking on the Info button. The color determines whether this movement involves an attack or supporting units for defense.
You can also use the arrow keys on your keyboard to navigate the world map.
