Extended information:

mahjong machine is divided into single-port machine, four-port machine, eight-port machine, ultra-thin machine and so on according to the way of pushing cards, and the characteristics of each machine are as follows:

Single-port machine: as the name implies, it is mahjong machine with only one card pushing port, and the cards are delivered to all parties through a conveying chain. Because the four ports have to be loaded in turn and the conveying device is needed, the loading speed is slow, it takes about 2 minutes to complete the loading action, and the failure rate is high. Among the existing types of mahjong machine, the single-port machine appeared the earliest, which has basically been eliminated, and only exists in some second-hand mobile phone markets.

Four-port machine: There are four card-pushing ports, and there is no conveying chain, so you can play cards at the same time with four ports, so the card-playing speed is fast. Generally, the card-playing action can be completed in 18 seconds to 35 seconds. Through extremely reasonable mechanical design, it achieves the characteristics of stable performance and fast shuffling speed ... Four-port machine has become the mainstream of the market.
