How about Chengdu Star Legend Entertainment Co., Ltd.?

It's not so good. It's purely a cheat people company. It's only allowed to lose, but not to win. If you win, they will shut down the machine, saying that the machine is out of order. Then you lose thousands of coins, and the machine is not out of order. If you win hundreds of coins, they will shut down the machine, saying that the machine is out of order or there is no money to add. Directly, you are only allowed to lose, but you are not allowed to win. I have experienced it first hand.
