Despite massive strides in computer technology and in particular video graphics, contemporary video poker machines are little different from their primitive forebears. Video poker fans are keen that their game is kept as ‘traditional’ as possible, and video poker has not developed in the same way that online slots games have evolved to be feature-rich monsters.
For those who are willing to learn these games, it is well worth taking the time to understand video poker strategy. Many of these machines offer the best return to players (RTP) of virtually all of the casino games that are available online. In fact, when played in real world casinos, video poker games are the only ones where players who play perfect strategy can have a positive expectation. This does not include players who card count in blackjack.
The strategy charts for all non-wild card games are organized the same way. The hand with the highest average return goes at the top of the strategy chart. For most video poker pay tables that hand is the royal flush. It is followed by lower paying hands and partial hands in order of decreasing return. Keep in mind that partial hands that are not winners themselves will at times be included above hands that are winners because they have an average return (for all possible outcomes) that is higher than a dealt winning hand. For example, in most games four cards of a royal flush is listed above a full house because of the possibility of that hand turning into a royal flush. However, that is not the only hand that can be made from a hand with four cards of a royal flush. There is also the possibility that the hand could become a straight flush, a flush, or a straight with the proper cards being drawn. See the examples below.
Despite the importance of finding the best machines, most players don't. That's why casinos can offer both decent and lousy machines in the same casino and be confident that gamers will still play the lousy ones. They have to keep some good machines, otherwise they'd lose all the players who know what they're doing. But most of the machines will be bad, and most gamers will play them anyway. Heck, in Vegas even casinos and supermarkets have video poker, with absolutely terrible paytables, but people will still play them rather than going across the street to a casino where they can get seven times better odds. Go figure.
