What are Locks?
World Lock is the oftenly used and the main economic lock in the Growtopia. Locks are items which can restrict specific areas to specific people, determined by the owner of it. Locks come with a multitude of features allowing you to have control of locked areas. Locks can be used for private use or can be shared with others. There are several locks available to users through the Store. Each lock varies in price according to how much can be done with that specific lock. Trying to modify items on area locked displays a message that says: That area is owned by <owner of the lock>
The locks have multiple features that they all share. These are some of them: adding users to lock and setting to public. Adding users to lock allows a person you specify, by tapping/clicking them, to have access. Setting a lock to public allows anyone to build or destroy blocks within the locked limits.
If a user is offline for 180 consecutive days, any locks placed (excluding World Locks) can be destroyed in 1 hit by anyone, but the lock will not be returned. (this is Lock Decay)
If the owner of a World Locked world is inactive for over a year the world will be reset.World Locks never decay. If they happen to, the world will be reset.
