Calling: chii, pon and kan

Chii: a sequence from the left

Chii completes a sequence, but only with the discard of the player on your left. Holding 3 4, you can chii 2 or 5.

The player on your left discards 5. Complete 3 4 with it.

Only from the left

The player on your left plays just before you, so chii takes "your" turn's tile. Pon can take anyone's discard.

Kan: four of a kind

R R R R

A kan (quad) is four of a kind. It counts as one set. There are two kinds:

• Open kan: call the fourth from any discard, or add it to a pon you already have.
• Closed kan: you drew all four yourself. Your hand stays closed.

After any kan you draw a replacement tile from the dead wall, and a new dora indicator is turned over: an extra dora for everyone.

You hold three red dragons, and the player on your right discards the fourth. Make a quad.

Who gets the tile

Several players may want the same discard. A win beats everything; pon and kan beat chii.

The cost: you lose riichi

A closed hand that reaches tenpai can always declare riichi, and riichi is a yaku by itself: it makes almost any closed hand winnable.

Call once and riichi is gone for the rest of the hand. Your hand is now an open hand, and it needs a yaku from its tiles. A careless call can leave a complete hand that can never win.

You called chii on 1 2 3, and now 8 is discarded. Can you win?
