Pung

A grouping that consists of three identical tiles. 

Joker tiles are allowed and up to three Joker tiles can be used in this grouping, depending on how the grouping is exposed. 

If the exposure occurs due to claiming a discarded tile the exposure can contain one (1) or two (2) Joker tiles. 

If the exposure occurs due to a player declaring Mah Jongg and exposing all of their tiles, the exposure may contain up to three (3) Joker tiles.
