The way video poker strategies are usually expressed is a list of hands you might get on the deal, in order from best to worst. For any given hand, look up all viable ways to play it on the list and go with the one that is listed first. If you don't see a play listed, like suited 10/A, then never play it. Here is such a strategy for Jacks or Better.
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.
So far we have looked at low variance and moderate variance video poker games. Low variance games have the advantage of a smaller bankroll size requirement and relatively simple video poker strategy. This comes at the cost of playing a somewhat boring game. Moderate variance video poker games are more exciting to play because they have more high paying winning hands. The excitement factor is offset, however, by higher bankroll requirements and somewhat more complex playing strategy.
You learned in chapter 3.5 that progressive video poker has one (the royal flush) or more (other high paying hands such as a four of a kind) jackpots that increase as the game is played. You also learned that as the progressive jackpot increases, the strategy to play video poker changes so that more of the close decisions are decided in favor of saving for the higher paying and less frequent jackpot hand rather than some more frequent but lower paying hands.

Online gambling is largely unregulated in the U.S.  That means the casinos serving U.S. players generally don't answer to anyone.  If you have a problem with a casino (like they won't pay you), then you're usually out of luck.  I can't count how many players have written to ask me for help because they didn't get paid by some other casino.  (Not that I helped them—if a dodgy casino won't pay you then you're on your own.)

But that is where the similarity with random slot machine play ends. The video poker player has total control over the initial five cards that have been dealt. It is his or her choice what to do with those five cards. The decisions about whether to keep all of them, discard all of them, or anything in between is totally theirs. It is actually totally yours. After all, you are the one reading and learning from this guide.

Stick to the proper way of how to play video poker as well as video poker strategy and you won't necessarily be able to become a professional video poker player, but if you're looking for the one casino game besides traditional poker where you can get positive expected value, or at least a very low house advantage giving you hours of play for a very small investment, video poker may be your game. 
Video poker offers some of the best odds in the casino. It's a good alternative to slot machines since you still have the chance of hitting a big jackpot, but you're about five times more likely to actually get it.  Slot players should seriously consider graduating to video poker, because they're much more likely to win that way.  The only catch is that to enjoy the good odds, you have to learn the proper strategy.  If you just guess then you could easily do worse than with slots.  But you came to the right place, because we'll cover strategy here.
Do not draw to a four-card inside straight -- one in which the missing card is in the middle rather than on either end -- unless it includes at least three high cards. A four-card open straight is one that has space open at either end to complete the hand; for example, a hand of 4-5-6-7 can use either a 3 at one end or an 8 at the other to complete the straight. An inside straight has space in the middle that must be filled to complete the hand; 4-6-7-8 needs a 5 to become a straight. Open straights give the player a better chance, with twice as many cards available to fill the straight.

A straight is a hand with consecutive ranks, like 9? 7? 10? 8? 6?.  Notice again that the cards don't have to appear in order.  The order of face cards, from lowest to highest, is Jack, Queen, King, Ace, which we abbreviate J, Q, K, A.  An ace can also count as 1, to complete a straight where the other cards are 2, 3, 4, and 5.  But it can't count as both a low and a high card, e.g., Q K A 2 3.
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.
If you choose the machine on the right, you'll lose your money six times faster!  And your chances of winning will be far less.  If the reason isn't obvious then consider this:  If the player is getting back 99.54% and 97.29%, that means the casino is keeping 0.46% and 2.71%.  The casino profit on the second machine is 2.71 ÷ 0.46 = 5.9 times higher.
Just as in the quick version, a few hands are never broken up. Obviously, if you're fortunate enough to be dealt a royal flush, you hold all five cards and wait for your payoff. (On payoffs this large, the machine will flash "Jackpot!" or "Winner!" In these cases the winnings will be paid by an attendant rather than by the machine. Do not put more coins in the machine or attempt to play another hand before you are paid for the royal flush.)

That's a pretty lengthy list for a beginner, but it can be shortened considerably by taking all those three card straight flushes -- open, inside, double inside, with high cards, without high cards -- and lumping them together just below four high cards. That'll cost you a few tenths of a percent, but when you're comfortable with the rest of the strategy, you can start breaking down the categories for more expert play.
Well, the charts on our site are on roughly accurate to within 0.1% of perfect play. So, if you find that game that returns 100.5%, you would be actually earning about 100.4% with our charts - not too bad. Not many charts get much closer than 0.1% because they would have to be extremely long and complicated to explain the subtle differences in rare hands.
