A Treasury is a small area within which many valuable rewards are hidden. You can encounter it in temporary expeditions, which give you a chance to discover various rewards and power-ups.

How do I unlock the Treasury?

The Treasury can be unlocked by purchasing the Secret Treasures bundle.

Tap the lock icon above the Treasury gate to open the Secret Treasures screen.
Here, you can preview all the possible rewards before making a decision.

Unlocking the Treasury gives you access to that specific set of rewards and lets you collect everything stored inside.

Each Treasury you find during an expedition is unique and must be opened separately.
