The online casino gambling sites have given us the opportunity to play a huge range of gambling games including all the traditional casino gambling games such as roulette and blackjack, plus a massive selection of slots gambling games. However probably the biggest influence that online casino gambling sites have had on our gambling habits is in the rise in popularity of poker gambling. There is no doubt that many more of us are now gambling on poker online and even entering poker tournaments since the introduction of online casino gambling. Although those of us who have ambitions to play in poker tournaments or play against other poker enthusiasts on one of the online poker forums tend to concentrate on the Texas Hold’em format of the game, we should not forget that there are many other forms of poker gambling available at most of the online casino gambling sites. There is even a poker game very similar to Texas Hold’em on most sites, called Omaha poker, which also uses five community cards and therefore entails multiple betting rounds. We have included the rules of Omaha poker on our gambling games pages, but in short Omaha poker gambling differs from Texas Hold’em poker gambling as follows. Each player is dealt four cards face down instead of two, but must use two and only two of these hole cards in their final showdown hand. On the face of it this does not seem to be a major difference, but in practice it certainly affects the potential value of the hole cards in the first few betting rounds. For example holding three of a kind in your hole cards is not as good as it may seem because you can only use two of them and only one remains in the deck to improve the hand. Another important difference is that because three community cards have to be used by all the players it is not possible to have two flushes of different suits in the showdown.
