It was based on the Daming Empire of 276 years of Chinese rule in 1368-1644. Therefore, the game benefits from a rich empire image as it is set in the Ming Palace. The symbols on the scroll include the emperor himself, the ship and the palace - the latter is a symbol of the wild, replacing the male emperor (Hongwu Emperor) and the empress (Queen Xu). If you manage to get 5 on the payline, then it will also pay your line bet 2000 times.
One thing to note about the Daming Empire is that the lines pay in both directions - which greatly enhances your winning potential. In terms of functionality, there is only one - Treasure Room Bonus feature. Play when you get 3 or more of the same type of continuous scatter (ie on reels 1, 2 and 3).
