One of the biggest effects of the increasing popularity of online casino gambling has been the surge in interest in gambling on poker. Poker has become the gambling game of choice for a great many casino gambling fans and even the poker tournaments have seen a massive increase in the number of applicants for a seat. Texas Hold’em is undoubtedly the favourite poker format for serious poker gambling enthusiasts, but there are other equally exciting and interesting poker gambling formats available on the online casino gambling sites including Omaha poker. In fact Omaha poker gambling is very similar to Texas Hold’em because Omaha poker also uses five community cards and therefore also includes the popular element of multiple betting rounds. We have included the rules of Omaha poker on our gambling games pages, but here is a brief summary. In Omaha each player is dealt four cards face down instead of two, but must use two and only two of those hole cards in their show down hand. It is this stipulation regarding how to use the hole cards which leads to the big difference between Omaha poker and Texas Hold’em poker, particularly in the early betting rounds. Normally for example holding three of a kind in a poker hand would be excellent news, but in Omaha poker if the hole cards include three of a kind, only two can be used and of course there is only one at most still in the pack. We should also point out another element of Omaha poker which may not be immediately apparent and that is that it is not possible to have two flushes of different suits in the final show down hands, because every player must use three of the community cards. Once you understand these significant differences gambling on Omaha poker is just as exciting as Texas Hold’em and offers a bit of variety for poker fans.
