Unlike slot machines, video poker games allow players to have a say in the game they chose to play. Like slot machines, randomness is also involved. The instant the “Bet Max Credits” or the “Deal / Draw” button is pressed the five cards to be dealt are determined based on a random process. After the cards to be held are selected by the video poker player, the cards that replace those not held are also determined by a random process at the instant the “Deal/Draw” button is pressed.
But that is where the similarity with random slot machine play ends. The video poker player has total control over the initial five cards that have been dealt. It is his or her choice what to do with those five cards. The decisions about whether to keep all of them, discard all of them, or anything in between is totally theirs. It is actually totally yours. After all, you are the one reading and learning from this guide.
Here's where our strategy list comes in.  Notice that a low pair is #9, while four to an outside straight is #10.  The low pair is higher on the list, so we hold the pair.  In fact, you almost always hold pairs in Jacks or Better.  We'll discuss exceptions below, but in general, always lunge for a pair, and then do a quick check to see if you have anything better, since you probably won't.
In the early 1970s, when video poker was introduced and was still struggling for acceptance, the machines were usually referred to as "poker slots." And video poker has a lot in common with slot machines. They are easy to use, requiring no interaction with a dealer or with other players. Card combinations, like slot reels, are governed by a random-number generator.
Well, the charts on our site are on roughly accurate to within 0.1% of perfect play. So, if you find that game that returns 100.5%, you would be actually earning about 100.4% with our charts - not too bad. Not many charts get much closer than 0.1% because they would have to be extremely long and complicated to explain the subtle differences in rare hands.
