Frequently asked questions
What does calling koi koi mean?
It means you keep playing after forming a yaku. Your next score doubles, but if the opponent completes a yaku first and banks it their points double instead, so judge the risk before you shout.
How long is one full game?
A full game runs twelve months and takes about three to five minutes. You can resign anytime, and the final score is the point difference times ten plus your total yaku points.
