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.
Know how to play a basic game. Video poker is simple and similar to regular poker in that you are aiming for a hand that will give you the most return. To play video poker you will tap on the cards you wish to keep or on a button on the console, and then draw cards you wish to replace. You win by having a traditional poker hand, and the amount you win is determined by the machine you are playing on.
Video poker machines started to become commercially viable following the integration of a monitor that looks like a TV screen. This allowed players to enjoy a 100 percent computerized game. The first ever computerized video poker game was developed in the mid-1970s. It was very primitive compared to modern day video poker games but it was the first ever computerized video poker machine that paved the way for other video poker games. The popularity of these machines started to skyrocket when a company called SIRCOMA (Si Redd’s Coin Machines) introduced the video poker game, Draw Poker, in 1979. SIRCOMA is now one of the biggest gaming developers for land-based and online casinos, going by the name IGT (International Game Technology).

The minimum hand you need to win is a pair of Jacks. So in this hand we'll hold the Jack, hoping that we'll draw another Jack. We hold the Jack by tapping the picture of the Jack on the screen, or pressing the button for it on the console.  Then we'll tap the DRAW button to get four new cards, hoping that one of them is a Jack to match the Jack we held.
An inside straight is a would-be straight with a hole in the middle. 9? 2? 10? 8? 6? is an inside straight because only a 7 will turn it into a straight.  The distinction between outside straights and inside straights is important because in Jacks or Better we will never try to turn an inside straight into a straight.  It's too hard, since we have only one chance of completing the straight.
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.
