A Chow takes the previous player’s discard to complete three consecutive suited tiles. A Pung takes any discard to complete three identical tiles.
A Kong contains four identical tiles and may be exposed, concealed or extended from a Pung. Draw a replacement from the back of the wall after declaring it. A winning claim normally outranks Pung or Kong, which outrank Chow.
