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.
Holding cards based on what you feel is correct or holding based on the flow of the cards are both technically strategies. But the video poker game manufacturers set up pay tables based on the math of the game so the casinos will be sure to make a profit from them. Therefore in order for you to make the most of your video poker playing experience, you need to use a strategy that is based on the same math.

Video Poker play is relatively straight forward. The play of the game has similarities to other casino games, but it is definitely more complex than playing slot machines. To properly play a slot machine, you simply bet an appropriate amount to maximize your return from the game and either pull the handle or hit a spin button. There is nothing else to so. While it may be true that some slot machines have a button to immediately stop the spinning and go to the final result, pressing this button does not change the outcome; it only helps you lose your money a bit faster.
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.
