Flash Chests!
This is a very short and exciting event that lasts only 24 hours, so every moment counts. During the event, you collect special event keys, use them to open chests, and receive lovely rewards for your city.
The rewards available from the chest can be seen on the right side of the event window, so you always know what treasures may be waiting for you.
How the event works
1. To open a chest, you need 25 event keys. This price stays the same throughout the entire event, so there are no surprises — just open chests and enjoy your rewards!
2. In total, you can open 18 chests during one Flash Chests event. Once you have opened all of them, the event will disappear from your game, even if the event timer has not ended yet.
3. Any unused event keys will stay with you until the next launch of Flash Chests.
