Zhan Wu Men Emperor Gate
You will get a win and a multiple bet plus you will get a free spin. During these free spins, the same prize can be re-triggered indefinitely, so it can be of great value. To get the multiplier and free spin, you will be able to choose from the five images of the emperor; everyone has a mysterious value, but you can get some kind of reward. You can also change the value of the coin from a minimum of 0.01 to 1.00, and you can bet up to 10 coins per line. All coins and lines must be of the same value.
If you want to take more risks, if you win, you can challenge the emperor to participate in the gambling war. Instead of collecting your money, gambling it has a chance to win a higher bonus.
