A Dimensional Jar is a non-mergeable object which sometimes (the chance is higher the higher the object level is) appears upon merging objects, usually higher-level ones. The object it contains is a clone of the item that was just merged. Upon creation, a timer for 1 hour will start, which counts down to when the Dimensional Jar disappears. The timer cannot be stopped, even if you bubble it. By tapping the jar, a special offer appears to open the jar for Magic Gems.
Dimensional Jars containing higher-level object require more Magic Gems to open. Refer to the merge chain of the particular object to view these prices. The size of the jar correspond to the size of the object inside.
Every Dimensional Jar can be sold for 50 Coins, regardless of content.
