Origin
The exact origins of Omaha Hold’em, also known as Omaha, are unknown, but some speculate that it may be related to the game Twice Three, which was popular in Chicago and Detroit at the time. Omaha has also been known by other names, including "Fort Worth," "Nine Cards," and "Oklahoma Two by Four." For some, the name suggests that it originated in the Wild West, and owes its name to the town of Omaha on the plains of Nebraska. Next to Texas Hold’em, Omaha is the second most played poker variant in the world.
Sin City
It was in Sin City that Omaha poker really took off. Legend has it that Robert Turner, winner of a WSOP bracelet in seven-card stud, introduced the game to William "Bill" Walter Boyd in Vegas in the 1980’s. Boyd, who was then card room manager at the famous Golden Nugget Casino, officially introduced Omaha to the casino under the name "Nugget Hold'em."
Stardust
It was at the Stardust casino, another Las Vegas gaming heavyweight, that the first Omaha poker tournaments were held in 1983. Such was its success that it was even dubbed "the game of the future". Traditional PLO has come a long way since then, and today there are even numerous variants.
