A full-fledged four-player mahjong that allows four players to play against each other. It consists of 8 satellites where adults can relax in a luxurious atmosphere, and a large live monitor that makes the match more hot, such as real-time nationwide online matches, replays of past famous names, national rankings, and seat information. You can play with peace of mind with a monitor that uses a special filter that prevents your hands from being seen. Compatible with the network service "MJ.NET" using mobile phones, you can carefully refer to detailed match history and rankings anytime, anywhere. Furthermore, by using the "MJ MEMBER'S CARD", you can enjoy new ways to enjoy the network, such as setting nicknames, rank systems, and equipping items.
