Video poker made its entry to the casino in the seventies; and is today one of the most popular forms of gambling. For the player who likes a game of skill, a low house edge, the possibility of large wins, and the anonymity of playing alone there is nothing else that can compare to video poker. The rules of video poker are simple; you play 1 to 5 coins, the machine give you five cards, you choose which to hold and which to discard, the machine replaces your discards and pays you off according to the value of your hand.
The game that you should learn first is Jacks or Better. Most of the other games are variations of this one. Although space does not allow me to give you the complete strategy in this article, you can find free strategy charts at The Wizard of Odds for Jacks or Better, Deuces Wild, Double Bonus Poker, and more. Sites like Video Poker Trainer allow you to practice playing online and will correct you when you deviate from the optimal strategy.

Unlike traditional slot machines, video poker is THE ONLY game where the pay table clearly indicates the return on your gambling dollar, based on your ability to play mathematically correctly. By practicing your favorite game for free at home, you can learn to play perfectly. Not only can you win more money, but you can also enjoy wining, dining and entertainment set aside for the casino's best players.
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.
Slot machines are extremely popular. One of the reasons for their popularity is that they are easy to play. The only skill that is necessary is to be able to insert money into the game and press a button or pull a lever to start play. That is it. From that point on, everything that happens depends on luck. The results of slot machine spins are based totally on randomness. The instant the slot player presses the spin button the result of that spin is locked in. Whether it is (most likely) a loser, a small winner, a moderate winner, or a jackpot winner has already been decided. Slot players can do nothing to change the odds either for or against them.

An inside straight is a would-be straight with a hole in the middle. 9? 2? 10? 8? 6? is an inside straight because only a 7 will turn it into a straight.  The distinction between outside straights and inside straights is important because in Jacks or Better we will never try to turn an inside straight into a straight.  It's too hard, since we have only one chance of completing the straight.
Winning a slot machine jackpot is based solely on luck. You put your money in the machine, hit the spin button and hope that Lady Luck will invite you to dance. There are no decisions to make that will change the outcome of the spin. On the other hand, many table games require skill and the decisions you make can determine whether you win or lose. Most table games when played properly have a lower house edge than the slot machines. Knowledgeable Blackjack players know that learning basic strategy will reduce the house edge to less than one percent.
