The “Gifts” tab gives you an opportunity to open clan chests sent by allies.

You can get a chest any of the following ways:

1. Completely explore a crypt.
2. Defeat a heroic monster squad.
3. Get into the top-100 of any tournament.
4. Buy any package on the offers’ page.

Once you see a new chest in the “Gifts” tab, you only have 20 hours to open it . Otherwise, the chest expires and you will have to delete it.
