Badugi is a poker-like game played with four-card hands. To win the pot at the showdown you need to have the lowest set of cards with no two cards of the same rank or suit, ace ranking low. The best possible hand is therefore A-2-3-4 with one card of each suit.
There is some controversy over the origin of this game, which has been played at least since the 1980's. Bill Rosmus reports that in the 1980's in Winnipeg, Canada it was played under the name Off Suit Lowball in the back room of pool halls and back room poker clubs. Bryan Micon says he has been told by several Korean players that it was also played in South Korea in the 1980's. Nick Wedd reports that the Korean word baduk, or badug refers to a black and white pattern. This gives rise to the Korean name baduk for the board game Go, played with black and white stones. In Korea, if you have a black and white pet dog, you might well give it the name "badugi". Two high-low games featuring the "doogie" hand, a low four-card hand consisting of a different ranked card of each suit, were contributed to gambiter.com in 2000 by Bob Procter's poker group in North Carolina, and published on gambiter.com in 2002: Doogie and Buddys Game. They have suggested that the "doogie" hand may have been named after the TV character Doogie Howser. Badugi started to become well-known in the USA around 2004, popularised by Paul "Eskimo" Clark, who was a friend of at least one player from Bob Procter's group.
Any solid information on the history of Badugi or Off Suit Lowball before 1980 would be of great interest in helping to establish how old the game really is, and whether it was invented in Korea or North America, or even independently in both places.
The following explanation of how to play Badugi assumes that you are familiar with the general rules of poker.
Badugi can be played by from 2 to 8 players, using a standard 52-card pack. The cards rank from Ace (low) up to King (high).
When comparing hands, within each hand all the cards must be different in suit and rank. If a player has more than one card of a suit, or two or more cards of matching rank, some cards must be eliminated to create a valid hand. Examples:
5-9-
3-
J: only one diamond can be used so this is a three-card hand J-5-3.
7-4-A-4: only one four can be used so this is also a three-card hand 7-4-A.3-6-8-6: eliminating the 6 makes a valid three-card hand 8-6-3.3-6-8-3: in this case two cards must be removed - a club and a three - leaving a two-card hand 6-3.10-10-10-8: this is another two-card hand 10-8.6-5-4-2: only one heart can be used, so this is a one-card hand: 2.8-K-5-Q: this is is a four-card hand, also known as a badugi, though not a particularly good one K-Q-8-5.The rules for comparing hands are:
8-7-5-4 beats 9-4-3-2 because 8 is lower than 9.10-7-5-4 beats 10-7-6-A because 5 is lower than 6.K-Q-J-8 beats 3-2-A because any four cards beat any three cards.5-3-5-3 and another has K-Q-3-5 their hands are equal. These both reduce to two-card hands 5-3. The ranks of the unused cards and the suits of the cards are not considered. If these are the best two hands in the showdown the players split the pot.Badugi can be played as a fixed limit, pot limit or half pot limit game - see the betting page for explanation. As in any poker game, the turn to deal (or to have the dealer button if therte is a non-playing dealer) passes clockwise after each hand. If there are more than two players, the player to dealer's left places a small blind, and the next player to the left places a big blind, which is normally twice as big as the small blind. In a "heads up" (two player) game, the dealer places a small blind and the dealer's opponent a big blind.
The dealer deals four cards to each player, clockwise, face down, one at a time, and the players look at their hands. There is then a betting round, begun by the player to the left of the big blind. The minimum bet is normally equal to the big blind. If none of the other players does more than call, the player who placed the big blind is allowed to bet.
The players have three opportunities to improve their hands by drawing cards. Starting with the first active player to dealer's left, and continuing clockwise arounf the dealer, each player states how many cards he or she wishes to exchange, discards that number of cards face down to the muck (discard pile), and is immediately given an equal number of replacement cards face down by the dealer. Players can exchange any number of cards from zero to four: excahnging no cards is known as "standing pat".
After each round of drawing, when each active player has had an opportunity to draw cards, there is a new betting round, begun by the first active player to the left of the dealer. There are therefore up to four betting rounds altogether: before the first draw and after each of the three rounds of drawing. In a fixed limit game, the size of the bet doubles after the second draw, so that the third and fourth betting rounds are played with big bets.
If at any stage only one active player remains, that player takes the pot without showing any cards.
If there is more than one active player at the end of the last betting round, there is a showdown in which the active players display their cards in turn, beginning with the last player who bet or raised in the final betting round, or with the first active player to dealer's left if all checked in the final betting round.
Players show all four cards, even if because of duplicate ranks or suits they only have a three-card, two-card or one-card hand. The cards speak for themselves, and the holder of the best hand wins the pot. If two or more players tie for best hand they divide the pot equally between them.
