So why it is called Omaha - after all, as stated above, the game appeared in Nevada. The reason is as follows. Normal Hold'em was played in Nevada in two forms: the popular form of Texas Hold’em, where the player was allowed to use any five of the seven cards available to him, and other more rare form, where he must play exactly two cards from his hole cards. It was this rare form that was called Omaha (she is called for some reason the Greek Hold'em). Therefore, residents of Nevada have already used the word "Omaha” in order to identify the two cards from hole cards, which must be showed at the showdown.
