Flash Chests is a new limited-time event that replaces Seasonal Chests. You can use the keys you have already collected; they will be exchanged at a 1:1 rate.
Please note that the exchange depends on the season. Spring Keys can be exchanged during the spring season, Summer Keys during the summer season, and so on.
Flash Chests lasts for 1 day and appears twice a month, so keep an eye out for the event icon in your game!
How does the event work?
When Flash Chests is active, you will see its icon on the right side of the game screen. Click on it to enter the event window.
Each chest opening costs 25 keys.
There are 18 rewards available in the event. Every time you open a chest, you receive one random reward from the list. The rewards may include:
- a unique building;
- Superbucks;
- useful resources;
- puzzle pieces for Exciting Puzzles;
- and other helpful prizes for your city.
Where can I get more keys?
If you need more keys, you can purchase them in the Flash Key Shop.
What happens after I collect all rewards?
Once you collect all 18 rewards, the Flash Chests event will automatically end for you, even if there is still time left before the event timer runs out.
