There are two common methods for playing high-low split games, called “declaration” and “cards speak”. In a declaration game, each player declares (verbally or using markers such as chips) whether he wishes to contest for the high hand or the low hand. The lowest hand among those who declared low wins that half of the pot, and the highest hand among those who declared high wins that half. In a cards speak game, all players simply reveal their cards at show and the hands are evaluated by all players; high hand wins half of the pot and low hand wins the other half.
A complete hand is dealt to each player and, usually before (or after, but not both) betting, players are allowed to change their hand by discarding unwanted cards and being dealt new ones. Players may have to “purchase”/”buy” the new cards by putting a prearranged amount into the pot for each new card. Another version of draw allows players up to three chances to buy and change their hand, one card at a time, in the first three rounds of betting.
In traditional teen patti games, the player with the best traditional hand wins the whole pot. Lowball variations award the pot to the lowest hand. High-low split games are those in which the pot is divided between the player with the best traditional hand (called the high hand) and the player with the low hand. In this variation, there could be multiple players remaining in play at “show,” unlike the traditional or lowball where there are usually only two players left at show. There are no sideshows and players may opt out from betting by folding. Usually there are three or four mutually agreed upon rounds of betting where no player opts out, before having the showdown. Also, there is a limit of six-to-ten rounds of betting at the end of which there is a compulsory showdown.
In the event more than one player ties for either high or low, the pot can be further split into quarters or smaller fractions. For example, if one player has the high hand on show and two other players tie for the best low hand, the high hand wins half of the pot and each low hand wins only a quarter of the pot.
It is common, especially in cards speak games, to require a certain hand value or better to win the low half of the pot, called a “qualifier”. For example in an “eight or better to qualify low” game, a player with an eight-high hand (or lower such as seven-high) is entitled to win the low half of the pot (assuming his hand defeats all other low hands), but a player with a 10-high or 9-high hand cannot win, even if his hand is the lowest. In this case, the high hand wins the entire pot. There is generally no qualifier to win high, although one common variant is “any pair/no pair”, where a hand of at least a pair is required to win high and any hand with no pair is required to win low.
