There are too many Sealed Chests!

If you're sure you don't want to unlock a chest with Gems or Hearts there are a few ways to reduce the Garden space they use.

The primary method is, of course, Merging! Chests can be merged like other items, and you'll get rewards for discovering the top of the Merge Family like any other item!

If you just want the chest gone, tap and briefly hold to bring up the item info and sell the chest for coins.
