The Pocket kingdom is an item that was obtainable during the Raging Echoes League, given to players upon unlocking the Pocket Kingdomrelic. It provides the following effects:
Workers will work for 50% less coins, always have max approval, produce twice as many resources, and accrue resources every hour instead of every day. Note that 37,500 coins will be removed every hour. This equals a daily cost of 900,000 coins. (If the coffers are filled with at least 375,000 coins)
Note: the Pocket kingdom will continue to accrue resources even when the player is offline.
