Panguingue, also known as Pan for short, is a gambling Rummy game which is popular in the southwest USA. From four to eight players can take part in one game. It is played with eight decks of standard cards from which the 8's, 9's and 10's have been removed - 320 cards altogether. Often the odds are changed by removing one complete set of spades, leaving 310 cards. Sometimes the 3, 5 and 7 and occasionally the 2 and queen from a second set of spades are also removed, leaving a pack of 307 or 305 cards.
Rules will eventually be given on this page. Meanwhile you can read a description on the USPCC's Bicycle web site. Please note: as of December 2011 these rules still contained a confusing misprint (which was introduced in the 1999 edition of their rule book and not yet corrected) - the three short paragraphs near the bottom of the page, the first of them beginning "Any time a player holds exactly 31" have mistakenly been included from the description of a different game - they have nothing to do with Pan and should be ignored. Another description of Panguingue is available on Randy Rasa's Rummy-Games.com site.
Wayne's Pan Pad has information on Panguingue and tips on how to play, mostly within the Blog section.

The Pan Player web site offers Pan cards, supplies and information.
The game of Panguingue and its name may well have originated in the Philippines. Thierry Depaulis writes:
I've found it in José Villa Panganiban's huge Diksyunaryo-tesauro pilipino-ingles (Lungsod Quezon, 1972):
pangginggi n. Ilk. [Iloko] Tg. old-time card game using naipes cards of the Spanish era.
In fact this is confirmed too by the OED on-line version (1993 additions):
"panguingue, n. [ad. Tagalog pangguinggui.]"
