There are a number of online poker variations available. Some of them are given below.

Texas Hold 'Em Poker: It is one of the most popular version of poker worldwide because of how easy it is for people to understand its rules. In this game, everyone is dealt two cards face down and then after several betting rounds, five cards are dealt face up to the center of the table. These cards are community cards and can be used by everyone with their own two cards in order to make the best five card poker hand.

Omaha Poker: Omaha is same as Texas Hold 'Em, except the fact that instead of dealing two cards face down, each player is dealt four cards face down. The other major difference is that in Omaha, five card poker hand must come as a result of exactly two cards from your hand and three cards of the five cards faced up in the center of the table.

Omaha/8 Poker: Also known as Omaha Hi Lo Poker, this is a version of Omaha where the highest hand and the lowest hand split the spot. Winning low hands need to be at least an eight low or better.

7-Card Stud Poker: In this variation, players start with two cards face down and one card face up. As the game continues, players are then dealt three more cards face up and one more card face down, with a betting round after each card is dealt. The player that is able to form the best five card poker hand from the seven cards they are dealt is the winner of the game.

7-Card Stud/8 Poker: Also referred to as 7-Card Stud Hi Lo Poker, the game is played in exactly the same way as 7-Card Stud, but with a difference that half the game is won by the high hand and half the game is won by the low hand, provided that there is at least one low hand that is eight low or better.

Razz Poker: Razz is played in the same way as 7-Card Stud, except that the best hand is the lowest hand. There can be A-5 Razz, where the wheel low is the lowest hand. There can also be A-6 Razz, where aces are high or low and there can be 2-7 Razz, where aces are high.
