Pyrgia

Pyrgia (pyre-gee-ah) is a family of competitive card games, thought to originate with a Hobgoblin game of this name (hobgoblin for 'campfire.') All versions of the game have a significant element of chance, but draw much of their gameplay from bluff and betting.
The earliest version of the game was played with a four-suit Manifold Deck. Players were dealt a hand of three cards.
A Halfling variant called chanson is played using the Eastern Deck. Played at a table, it added a common pool of three face-up cards, with players making a hand of five cards using their three and two of the common cards.
Fireside is a family of variants played using a deck of Daroka cards, excluding the high suit, using rules often attributed to the Vistani and other travelling tribes. The orc game of shield is one such variant. Fireside-type variants usually include some form of card-exchange, and treat the 1 as the 'ace', the highest card in the suit.
In stake variants, players are dealt a hand from a Foundation Deck - again, without trumps - with some cards face down and others face up. Cards are dealt one at a time, with betting occuring between deals based on the revealed cards.
Flow is a similar game played in Suto using the Celestial Deck and believed to have evolved from pyrgia games introduced by sailors visiting the Scaled Kingdoms. The zero card in a deck is high when playing flow-type games.
