Events and big projects
Storms and heatwaves, Epic Projects and Headquarters.
Storms and repairs
From level 35, storms and heatwaves can damage buildings. Repair them for Medals, which you trade for Civic Tokens, parts and Diamonds.
A damaged building pays no taxes and makes nothing until it is repaired. Missing the goods for a repair? Tap Buy missing and repair: they are bought with Diamonds and used at once.
Medal trades
| Trade | Medals |
|---|---|
 Civic Token | 8 |
 2 random parts | 12 |
 Diamond | 25 |
Live events
Every 6 hours (0, 6, 12 and 18 UTC) a live event starts for 5 hours: you race mayors of about your level in your league, from the Hamlet League to the Skyline Legends. Your league is set when you join and stays until the end. The first three of each league win extra Diamonds.
Event Diamonds for finishing live events are at most 6 a day; podium prizes come on top.
Epic Projects
From level 73, a Tower Zone of tier 6 or higher can become an Epic Project: a landmark skyscraper built in three stages that boosts the homes around it. You can have 1 at level 73, 2 from level 89 and 3 from level 94. An Epic Project grows no further as a home.
| Stage | Cost | Time | Residents | Boost nearby |
|---|---|---|---|---|
| 1 |  60,000 | 2 h | ×2 | +6% |
| 2 | 150,000 | 4 h | ×3 | +10% |
| 3 | 300,000 | 8 h | ×4 | +14% |
Headquarters and canals
Canals open at level 34: build waterways with boats through your city.
Headquarters make one kind of special building (parks, sports, culture and more) work better.
