You can collect Gifts on the City map during an Event. They are stored in a chest located on the central town square. Tap the chest to open the Gifts using event stars.
The Gifts may contain: energy, coins, tools, assemblers, collection items, one-time boosters, weapons, and keys to all doors.
You can get stars:

- by completing event quests.
