Practicing video poker strategy by using a computer program or smartphone / tablet app is far more effective than practicing manually as described in section 7.2. The only real problems that might get in the way of you doing so are that you need a computer or smartphone / tablet and you need the program or application. As mentioned previously, there are several good video poker programs and applications available. They are also quite reasonably priced. If you do not have a video poker application, I strongly suggest you purchase one as soon as you can. You can practice manually for a while until you receive it, so you will not be just sitting around and doing nothing while you wait.
The wild card is a feature that is offered at some, but not all, of the video poker variants. The wild card is always the Joker or the Deuce. This wild card can be substituted for any other card from the deck in order to help players achieve a winning poker hand. In Deuces Wild, for example, the wild card is the 2, which is where name of the game comes from. Another game is Joker Wild, where the Joker is the wild card. Some games might have more than one wild card, such as Joker and Deuces Wild. In this game, the 2 and the Joker are wild cards.
Less interesting and less impressive was the page about “Video Poker’s Greatest Hits”. ( One of the aspects I found disappointing about this sales page was the lack of a price listing. There’s a button for a free trial, and another “buy now” button, but I don’t think I should have to click “buy now” to get a price. I did click through, and the price is only $19.95, but the software is limited to 8 video poker games.
The lite version allows you to configure payoff tables and create a single strategy chart for any game you input. You can also use the lite software to practice playing the various games. It lacks some of the other fancier features, but those are a bit “fluffy” anyway. You can download free demos from the site before making a decision as to whether or not it’s a good purchase for you.
The minimum hand you need to win is a pair of Jacks. So in this hand we'll hold the Jack, hoping that we'll draw another Jack. We hold the Jack by tapping the picture of the Jack on the screen, or pressing the button for it on the console.  Then we'll tap the DRAW button to get four new cards, hoping that one of them is a Jack to match the Jack we held.
Tap any cards that you want to keep. You will see some indication that the card you have selected has been held. When you’re satisfied with your selection, hit the ‘draw’ button to receive your final poker hand. If you’ve managed to land a poker hand with at a least the value of a pair of jacks, then you will be paid according to the pay table as presented with the game.
Find the good games.  The VP games with the best paytables are findable, but they're rare.  Naturally the casinos prefer that you play the stingier machines.  In general, the Strip casinos have the worst machines, and everywhere else it's better -- off-strip, downtown, and locals casinos.  But while good machines are rare on the Strip, some do exist.  VPFree2 can help you find the good-paying machines.
So it really pays to hunt out the good machines!  But it's actually pretty easy, because the readers of a website called VPFree2 scout out the best machines and post their locations on the site.  Using that site you can see that you can there are 9/6 Jacks or Better machines on the Strip at Cosmopolitan, New York New York, Riviera, Treasure Island, and others.  And in downtown and off-strip casinos, the good games are more common, and available at lower denominations.
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.
