GG Fishing 3D: What is the key and vault icon above the hall?
Shows the keys and treasure chests collected during the fishing process. When the fish is caught, a key is randomly received. The key icon shows the number of keys that have been collected.
When you collect 5 keys, you will get a treasure chest. Depending on the number of keys, it is also possible to get several treasure chests.
Open the Treasure Chest and get a free warhead.
