If you visit the Wizard of Odds site, you can find a free video poker game available in your browser window that includes auto-hold features and warnings when you’re about to make a mistake. This is a free Jacks or Better 9/6 game: http://wizardofodds.com/play/video-poker/. You can even update the pay tables for this game to something other than 9/6 Jacks or Better. For the price, this training program is hard to beat. The game also features a “more games” button which opens up a screen where you can choose from three dozen different games, including the following:
Video Poker is the only game in the casino that actually shows you the information you need to determine the house edge and develop the proper playing strategy to attain the highest return possible. Most video poker players are totally unaware of how to use the information available to their advantage. They will plop down on any close or convenient machine and play by hunches in the hope that they will get lucky. This guide is written to help players get the most out of their video poker playing efforts.

Break up a flush or a straight only when you have four cards to a royal flush. That is, if you have ace-king-queen-jack-9, all of clubs, discard the 9 to take a chance at the big payoff for the 10 of clubs. That still leaves open the possibility of a flush with any other club, a straight with any other 10, and a pair of jacks or better with any ace, king, queen, or jack.

Joining the slot club will give you additional rewards for all of your play so it is well worthwhile since you would be playing anyway. Setting a budget is a crucial step as you should only ever gamble with money you can afford to lose. You should also expect that even with the best possible pay tables you will not win on every session you play - that's why it's called gambling.

Elsewhere on this site I show you how to figure your average loss for an hour of play.  In summary, you multiply the house edge by the bet size by the number of rounds per hour.  On a 9/6 quarter Jacks or Better machine with proper strategy, that would be 0.5% x $1.25 (remember we're playing 5 coins at a time) x 400 hands per hour = $2.50 per hour.  Not bad.  Except that the formula doesn't work for video poker in the short term.  That's because you'll hit the royal only once every 66 hours on average, and while you're waiting for the royal, the return on the game isn't ~99.5%, it's ~97.5%.  So you're more likely to lose 2.5% in the short term rather than 0.5%.  So we can expect our hourly loss to be closer to $6.25/hour than $1.25/hour while we're waiting for the royal.  Still, $6.25/hour is pretty cheap.  On a slot machine your loss would be closer to $40 an hour.  So you can see why I'm so eager to switch you from slots to VP.
So far you have learned how video poker started and grew. You have learned the basics of video poker play including return, house edge, and variance. You have learned how randomness actually works. You have also learned about several categories of video poker games that are available today. Plus you now know some methods of determining how large a bankroll you will need to play your video poker game of choice.
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.
Of course, you don’t actually have to memorize the strategies in order to play video poker reasonably well. Even if you want to play optimally, you can use visual aids whilst playing online. This is much simpler than trying to play from memory. However, as you play a particular machine more and more, you’ll find yourself relying on these ‘cheat sheets’ less and less. Instead, you’ll begin to notice that you have a better handle on the strategies needed to win on each different type of different video poker game.
Obviously, the more you bet, the more you will win for any given hand. With one exception, the win for any given hand and bet is proportional to the amount bet. However, notice that for a royal flush the win is 1000 for a bet of four coins and 4000 for a bet of 5 coins. The disproportionately high payoff of 800 per coin bet for a royal flush, with a five coins bet, is what economists would call an economy of scale. You will see this in almost every video poker game. If you don't bet the maximum number of coins, the cost of being short-changed on a royal amounts to about 2% of money bet, which is a lot. The wise video poker player will always bet max coins per hand.
Once I put $100 into a $0.25 machine and played it for a while.  I played it down to zero credits, and then I hit Four of a Kind, which saved me.  I played that down to zero again, and then I hit Four of a Kind again.  I played it down to zero credits a third time, and then hit Four of a Kind a third time!  But that was the end of my luck.  I didn't get it a fourth time, I just went bust.  Still, that was pretty unusual.
Following on from the lists above let's take a look at the reasoning behind each of the points. First the do's. The first two points cover learning the best pay table variations for your favorite games and finding them. By playing the best variations you give yourself a good starting point even before you make your first bet. Of course to get the most out of the good pay tables you need to play max coins on every hand and play with perfect strategy. 

Video poker is a popular form of gambling that provides an edge to skilled players. If you play a game with acceptable pay tables, use optimum strategy, and receive comps for your play, you can generate a slight return on your money over the long term. Video poker is often praised over slot machines, because the return on your money and odds of winning a hand are higher. 

Once I hit two 4 of a Kinds back to back.  The probability of hitting it once is 0.24%.  The chances of hitting it back to back are 0.24%2 = 0.0006%, or 1 in 179,000.  That's four times less likely than hitting a royal flush.  And I would have preferred the royal!  (By the way, purists will note that after you've hit a 4 of a Kind, the chances of hitting another four of a kind is just 0.24%, not 0.0006%, but I'm considering the probability of getting two back-to-back before I get the first one.)
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. 

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.
