Badugi (also known as Badougi or Padooki) is a draw poker variant similar to triple draw, but with differing hand values than traditional poker. The betting structure and overall play of the game is identical to a standard poker game, but unlike traditional poker which involves a minimum of five cards, players' hands contain only four cards at any one time. During each of three drawing rounds, players can trade zero to four cards from their hands for new ones from the deck, in an attempt to form the best badugi hand and win the pot. The object of Badugi is to win pots, the share of money put in by oneself and one's opponents during the hand. The winner of the pot is the person, who has not folded, with the best badugi hand at the conclusion of play (known as the showdown).
Believed to have originated in Asia, Badugi is becoming popular in the United States

Omaha hold 'em (or Omaha holdem or simply Omaha) is a community card poker game (often referred to as a "flop game") similar to Texas hold 'em, where each player is dealt four cards and must make his best hand using exactly two of them, plus exactly three of the five community cards. The exact origination of the game is unknown, but casino executive Robert Turner first brought Omaha into a casino setting when he introduced the game to Bill Boyd who offered it as a game at the Las Vegas Golden Nugget Casino (calling it "Nugget Hold'em".)
