Omaha is definitely a popular form of “community poker” but below are a couple variants.

Omaha 8 or better Omaha/8

Like most poker games it is used with a standard 52 deck of cards and can be played with a maximum of 10 players. Omaha/8 shows many of the same characteristics of Omaha. Each player receives four pocket cards where they must use exactly two. There are five community cards that each player uses exactly three to make their best 5 card poker hand. The main difference is that Omaha/8 is a split pot game. That is, half the pot is awarded to highest qualifying high hand (royal flush), and the other half is awarded to lowest qualifying low hand (A,2,3,4,5). It should be noted that the depending on a players hole cards they may win both the high and the low hand. All other variants of the game are exactly the same as Omaha in respect to blinds, flop, turn, river and showdown. Betting structure follows the same as Omaha.
