Hello, landlord, you must have the five cards of 13579 to win. Generally, you can split the side card and the clip card, not the straight card, but in certain circumstances, you can also split the straight card, or according to your own feelings. Before deciding to develop chess and cards, we must communicate our needs with developers. Communicate the development cycle well: The development cycle of chess and card games usually lasts between 15-30 working days. Because of some uncertain factors, specific evaluation is required before development. After all, after-sales is very important. After all, if there is a problem with the board game and the developers cannot quickly provide the corresponding solutions, it means that the operators may have to spend high maintenance costs, or even lead to the collapse of the game, resulting in the loss of a large number of players. Finally, sign the corresponding contract, which is a key step in the development of chess and card games. We can't be careless. Many developers are unwilling to sign contracts with customers. At this time, we need to be vigilant. Contracts are guarantees. If you want to develop Zhengzhou mahjong games, Dayou Network is a good choice. You can customize game products according to customer needs. One to one service, customized chess and card games according to customers' needs and players' habits, with guaranteed after-sales service.
