Card games in Mexico
Conquian is a Rummy game for two or three players using the Spanish 40-card pack which has been played in Mexico since the mid 19th century. From there it spread to the USA and over the following decades gave rise to the whole family of Rummy games which became popular throughout the Western world.
Paco is a relative of Conquian for up to 12 players using a quintipule Spanish deck (200 cards) in which the winning player is paid according to the cards in their melds.
Dompe is a relative of Knock Poker featuring a wild Joker and the possibility of winning with a 6-card hand.
Pokar is a Draw Poker-like game with the 40 card Spanish pack. Only four cards are dealt to each player, and the only valid combinations are four of a kind, three of a kind, two pairs and one pair (apparently there are no flushes or straights). Players can discard up to 3 cards and draw replacements. The ace of coins is a wild card.
Burro Castigado is a children's game, related to Pokar. Each player is dealt 5 cards and can discard up to 3 and draw replacements. Valid combinations are four of a kind, two pairs, three of a kind, one pair; the highest hand wins. There are no wild cards.
In Siete Loco the aim is to get a score as close to 7 as possible without exceeding 7. It is played with the 40 card Spanish suited pack. Pictures are worth half a point and numeral cards are face value. Each player is dealt one card initially and can ask for additional cards. There is a variation in which the aim is to get seven and a half points.
Malilla is a version of the Spanish game (there called Malilla or Manilla), played with the Spanish 40-card pack.
La Viuda (the widow) is the Mexican equivalent of the American game Whisky Poker.
I would be grateful for further information about these and other Mexican card games.
