Yaku / Points

The object of this game is to form special card combinations called "Yaku" from cards accumulated in a point pile. Once a yaku has been formed, a player can Stop to cash in points, or Koi-koi(keep going) to form additional yaku for more points.
Yaku has two subclass, first is "Dealt Yaku" which a player is dealt before play begins, second is "Formed Yaku" which a player forms in his turn.

Dealt Yaku

Yaku such that, if a player is dealt them before play begins, he is immediately awarded points. Play then ends before it starts, and the game continues to the next hand.

Formed Yaku

Players can gain cards in their point piles by matching cards in their hands, or drawn from the draw pile, with cards on the table. After a player's turn ends, if he formed at least one yaku (That is "Formed Yaku" listing below) in that turn, that player must then make a choice.

Points

A player forms yaku and stop, he gains all the points he is entitled to from the yaku he has. At the same time, the following rules is applied. So, judging "Stop" or "Koi-koi" by guessing you may reach 7 points or your opponent may form yaku or not is up to your ability to judge calmly, courage and tactics.

  • If a player gains yaku totaling 7 or more points when the hand is called, his score is doubled.
  • If a player is able to form a yaku before the player's opponent who called Koi-koi, his score is doubled.
  • *If a player beats his opponent to a yaku after the opponent calls Koi-koi in addition to scoring 7 or more points of yaku, his initial yaku score is quadrupled.
