Treasure Chests are any ordinary chest found deep underground in Dig Deep. They may include valuable treasure, such as gold pieces, gold, uranium, platinum, etc.
Opening 30 treasure chests will unlock the Pirate Avatar Skin.
- Blocks/items that are locked in the world (or haven't be picked up or prospected before), are displayed as a locked symbol, similar to the locked blocks/items in the shops, when opening a treasure chest.(As of the 1.8 update, this has been fixed/changed.[Verified])
- A way to bypass this is to break the chest, which will drop the item, which may be picked up.
