Key Mechanics

• Meld 面子

  3 consecutive or identical tiles, or 4 identical tiles grouped together, leading towards a winning hand.

• Pair (Eyes) 眼

  2 identical tiles grouped together, leading towards a winning hand.

• Sequence 順子

  A Type of Meld consisting of 3 (but not 4) consecutive tiles. Only Dots, Characters, and Bamboos can be grouped into a Sequence — Winds and Dragons do not have a numeric value and cannot form one. Formed by drawing from the wall or by Chowing.

• Multiplet 刻子（廣義）

  A Type of Meld consisting of three or four identical tiles. All Suits, Wind tiles, and Dragon tiles (except Flowers/Seasons) can form a Multiplet.

• Triplet 刻子

  A Multiplet of three identical tiles. Formed by drawing from the wall or by Pung-ing.

• Quadruplet 槓子

  A Multiplet of four identical tiles. Formed by drawing from the wall or by Kong-ing.

• Chow / Seung 上/吃

  Pick up the previous player's discard to form a Sequence with two tiles already in hand. Only allowed from your left-hand player; Pung/Kong takes priority if contested.

• Pung 碰

  Pick up any player's discard to form a Triplet. Skips the turns of players in between. Yields to another player who needs the tile to win.

• Kong 槓

  Pick up any player's discard to form a Quadruplet, then draw a replacement tile from the end of the wall. Skips turns in between; yields to a winning claim (see “Win by Robbing a Kong”).

• Concealed Kong 暗槓 (Um Gong)

  Self-draw the fourth tile of a kind already in hand, slide the Quadruplet face-up, then draw a replacement tile.

• Supplementary Kong 補槓 (Bo Gong)

  After already Pung-ing a Triplet, draw the fourth tile of its kind and add it to the exposed Triplet, then draw a replacement tile.
