Cities produce units per turn in the game. Turn is generally a 10 second period, in which at that interval, the number of units change on a territory tile based on the number of cities on that tile.
- Gold - Represents massive cities, produces 4 units per turn.
- Dark Gray - Represents major cities, produces 2 units per turn.
- Light Gray - Represents regular cities, produces 1 unit per turn.
- Black - Represents burnt cities, produces 0 units per turn.
Burnt cities occur when a battle over a territory has been going on for a set amount of time. Once the battle is over, the territory owner suffers a no or partial production penalty for that tile depending on which city was burnt during the battle. The burnt status goes away after sometime, and the city resumes providing regular unit production.
