Key

Keys are used to open Vaults and to purchase items in the Shop.

Green Keys, in particular, are also used to destroy your Headquarters in the event you want to move it, and also to unlock Uservault slots inside your HQ.

Regarding the White Key: On August 15, 2021 Kookoopuffs shared on Discord "For lower income countries, we’ll likely have a lower tier of vault. Advertising budgets are scaled to local income levels. But I expect there to be 1 to 2 more tiers below blue that we will deploy in lower income countries."

Regarding the Crystal Key: In the Hunters Lodge 5 on July 15, 2022 Illusionweaver introduced this new key type to be integrated in-game in "early August".

Acquiring Keys

Quests

Quests (such as Activity Quests like the Walking/Running Quest) reward players with keys for completing certain milestone goals. Blockchain Quests (such as those used during Events) do not reward players with keys, and instead cost keys to earn progress.

Keybooths

Keybooths were in the game for over a year and a half and allowed players to pick up a free key once per day. They were removed in mid-April 2022.

Prize Boxes

Players can receive bonus keys from Prize Boxes. Prize boxes come most often from solving vaults, but are also given in some other instances.

Forging Keys

Players can use the Forge on their inventory screen to create a higher tier key from 10 lower tier keys. For instance, 10 Blue Keys can be forged into one Green Key.

Uservaults

Players receive 1 Blue Key for every 20th key inserted into one of their Uservaults. These extra keys are sent to the player's Mail Box.

In-App Purchase

Beginning in "early August" Crystal Keys can be purchased from the Google Play Store or with collected in-game Cryptocurrency.
