When you visit a friend's city you can boost it. Each boost gives it 10% more taxes in the next full game hour.
Rules
- You can only boost real friends, players you are friends with. You only see the button with them. Members of your coalition are boosted in the coalition window (Coalition boost).
- You can give away 3 boosts per day, but each city only once.
- A city receives at most 3 boosts per day, together at most 30% more taxes.
- You collect received boosts in the Boosts window, one at a time or all at once. They then work in the next full game hour.
- Boosts not collected expire at midnight. The day counts on German time.
