Hello, landlord. I just found a company called Dayou Network Technology Co., Ltd. to develop this. Their company specializes in the development of chess and card games. There are many models, including the big league and the circle of friends and relatives. At that time, when I asked them to develop the game, the price was not expensive, but it had a high cost performance. The main reason was that the game was really good. Their company had more than 600 chess and card games, and there was a professional research and development team to carefully develop and professionally design for customers; Provide customers with a full range of services including R&D, construction and after-sales services. You can talk to them specifically.
