Overview

There are many types of poker games. While poker was originally played with each player receiving five cards and only one betting round, it has expanded to include hundreds of variants. Currently, the most popular one is Texas Hold'em, but other variants are very popular.

Here are some 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. Players can pass cards to each other. An example of this would be Anaconda.
3. 'Kill game'. When a fixed limit game is played and a player wins two pots in a row, the stakes are doubled.
4. Wild cards are added. This can range from simply making deuces wild to the wild 7-stud variant of baseball.
5. A twist round in which players can buy another card from the deck. If a player does not like their card, they can purchase another one by adding money to the pot. This is sometimes called a "Tittle."
6. 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.
7. Each player is dealt a certain amount 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
