In poker it is sometimes necessary to split, or divide the pot among two or more players rather than awarding it all to a single player. This can happen because of ties, and also by playing intentional split-pot poker variants (the most typical of these is high-low split poker, where the high hand and low hand split the pot).

Here are more common rule variations:

1. High-low split: the highest and lowest hands split the pot. Generally there is a qualifier for the low hand. For example, the low hand must have 5 cards with ranks of 8 or less. In most high-low games the usual rank of poker hands is observed, so that an unsuited broken straight (7-5-4-3-2) wins low (see Morehead, Official Rules of Card Games). In a variant, based on Lowball, where only the low hand wins, a straight or a flush does not matter for a low hand. So the best low hand is 5-4-3-2-A, suited or not.
2. Lowball (poker): The lowest hand wins the pot. There are different rules about whether or not aces count as low, and the effects of straights and flushes. The most common variants are Razz and Triple draw lowball
3. Players can pass cards to each other. An example of this would be Anaconda.
4. 'Kill game'. When a fixed limit game is played and a player wins two pots in a row, the stakes are doubled. In some split-pot games (e.g., Omaha), a player winning both halves of the pot may also cause a kill.
5. Wild cards are added. This can range from simply making deuces wild to the wild 7-stud variant of baseball.
6. A twist round in which players can buy another card from the deck. If a player does not like the purchased card, the player can purchase another one by adding money to the pot. This is sometimes called a "Tittle."
7. A stripped deck may be used. Poker was first played with only 20 cards. In the spirit of poker history, players will sometimes only play with a stripped deck. A popular poker game in Spain is played with cards 8-A. It is played similar to hold'em, except that one card is dealt at a time and you must use both of your hole cards.
8. Each player is dealt a certain number of cards. Then there is usually a number of community cards that all players can use. When forming a poker hand a player may use cards from his hand and the "community cards". Examples of community card poker include Texas hold 'em and Omaha hold 'em.

To split a pot, one player uses both hands to take the chips from the pot and make stacks, placing them side by side to compare height (and therefore value). Equal stacks are placed aside. If there is more than one denomination of chip in the pot, the largest value chip is done first, and then progressively smaller value chips. If there is an odd number of larger chips, smaller chips from the pot can be used to equalize stacks or make change as necessary. Pots are always split down to the lowest denomination of chip used in the game. Three-way ties or further splits can also be done this way.

After fully dividing a pot, there may be a single odd lowest-denomination chip remaining (or two odd chips if splitting three ways, etc). Odd chips can be awarded in several ways, agreed upon before the beginning of the game. The following rules are common:

* If playing a high-low split game and dividing a pot between the high and low hands, always award the odd chip to the high hand.
* If splitting a pot because of tied hands, award the odd chip to the hand that contains the highest-ranking single card, using suits to break ties if necessary (clubs ranking the lowest, followed by diamonds, hearts, and spades as in bridge).
* (Variation) Between tied hands, award the odd chip to the first player in clockwise rotation from the dealer. (Note that in a casino stud game with a house dealer and no button this gives an unfair advantage to players on the dealer's left, so the high card by suit method is preferred).
* (Variation) Leave the odd chip as an extra ante for the next deal. This is common in home games.

Sometimes it is necessary to further split a half pot into quarters, or even smaller portions. This is especially common in community card high-low split games such as Omaha hold'em, where one player has the high hand and two or more players have tied low hands. Unfortunate players receiving such a fractional pot call it being quartered. When this happens, an exception to the odd chip rules above can be made: if the high hand wins its half of the pot alone, and the low half is going to be quartered, the odd chip (if any) from the first split should be placed in the low half, rather than being awarded to the high hand.
