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.)
You should always place the maximum bet because it makes you eligible to win the grand jackpot prize of 4,000 if you get a royal flush. If you bet with 1 or 2 coins and get a royal flush, the payout will not be proportionally equal. If betting 5 coins is too expensive for your gambling budget, you can find a lot of .25 machines as online casinos usually offer their bets in denominations that include different sizes such as .25, 0.50, 1, 2, 5 and even 10 and 20.
In the right circumstances, however, the player sometimes will break up a flush, a straight, or a pair of jacks or better. If you do not have one of the "always keep" hands, use the following list. Possible predraw hands are listed in order. Find the highest listing that fits your predraw hand, and discard any cards that do not fit the hand. For example, if your hand includes jack of spades, jack of diamonds, 10 of diamonds, 9 of diamonds, and 8 of diamonds, you have four cards to an open straight flush in diamonds, and you also have a pair of jacks or better. The four-card open straight flush is higher on the list than the pair of jacks or better, so you would discard the jack of spades and draw to the four-card straight flush. You are giving up the certain 1-for-1 payoff for a pair of jacks, but you have a chance at a straight flush with either a queen or 7 of diamonds, could draw a flush with any other diamond, or still could finish with a pair of jacks by drawing the jack of either clubs or hearts.
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.
