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.
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.)
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.
