This is well worth the price. It helped me to improve my game within the first day of playing (One example: did you know that if you are dealt 2 pairs in Deuces Wild, you should keep only 1 of the pairs and draw 3 cards? You are better off to go for 3-of-a-kind or even 4-of-a-kind than trying for the Full House). It can let you know when you make a mistake, and analyze your play for each game with percentage of correct plays, how much you would have won/lost if you had made all correct plays, and other information.

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.)
It is not enough to just know the payback of a video poker machine. In order to achieve the maximum return, you must play the game using a set mathematical strategy. It is very important that you learn the strategy for each game and play them correctly. Making a few mistakes in strategy when playing can increase the house edge against you. Each video poker game has its own strategy. For example, you can not use the strategy for Jacks or Better when playing Deuces Wild.
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.

As you have learned in the first chapter, one of the main reasons for the popularity of video poker is it usually has a considerably higher payback than slot machines. In fact some games return more than 100 percent for a skilled player. Regardless of which video poker game you play, achieving the long term return percentage is dependent on getting your fair share of royal flushes. By a royal flush I mean the royal flush that really counts – the natural royal flush that is formed without the aid of a wild card. These generally pay 4,000 credits for a five-credit bet or 800 for 1.
One advantage that video poker has over regular slot machines is that you can determine the return of the game by reading the pay table on the front of the machine. Most video poker games use the combinations of hands that can be made from a standard 52 card deck. I say most because there are some Joker Poker Games that use one or two Jokers added to the 52 card deck. One popular variation of the game is Deuces Wild which uses a 52 card deck but the deuces are wild cards. With a set number of combinations that can be made from the cards used in the game, the payout can be calculated by how much the machine pays for each winning combination.

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.
