The Daming Empire is paid for by both lines - this 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).
In this function, you can choose 3 items for cash rewards - then apply the multiplier to your bonus based on the amount of scatter you need to trigger the feature. If you trigger it with 3 scatters, the multiplier will not be applied. If you have 4, all victories will be tripled. Now, if you get 5, your victory will be subject to a huge 10 multiplier! Unfortunately, there is no free spin feature, which is quite disappointing - Daming Empire is a simple slot machine game, but benefits from the medium to high differences. I won more than 300 times the grand prize in the basic competition.
