My first ko koi knowledge was from Yakuza 0, at that time I suffered a lot from the mini-games but the koi-koi was really attractive! After some time I got the game and began online battles with my weeb friends.
我第一次打花牌是在如龙系列里，即使被世嘉内嵌的小游戏折磨得死去活来，伤痕累累的我依旧发现了花牌的魅力。

The koi-koi rules are quite easy, once you understand them you could always check the wiki on the right bottom and calculate how many cards you could earn then decide when to koi or stop. That game needs both skill and luck. May the fortune be with you!
花牌规则很简单，四十八张牌按照花色和月份，可以有不同的得分组合，你可以估计自己和对方的手牌，并决定何时叫牌和停牌，虽然这游戏的最大影响因素还是运气，有时候你就是手气不好，愿天照女神保佑你！

Even I like the game, I have to complain that the online mode is really a nightmare with endless delay and bugs.
So far only the Japan server works fine for me, anyway seems there're almost no other weebs playing.
最后，这游戏的服务器烂得一批，如果你非要玩在线模式，那么只能祝你好运了，因为你将要独自与永无止境的缓冲和令人抓狂的延迟对战，只有日本服务器还勉强能用，当然，这里依旧并没有什么人。
