All video poker machines work behind the same premise. They are all a computerized version of your normal five card draw poker game. In each case, you are not playing a person, but rather you are playing alone and must attain at least the minimum poker hand required in order to win. This differs from game to game.
Each video poker game will deal you 5 cards and you must decide which cards to keep and which cards to discard. You will get a replacement card for each one that you discard. After you receive these cards, the hand is over and your hand will be evaluated to see what you have won.
What makes one video poker machine different from any of the others are the payouts and wild card designations. Also, the name of the video poker game is usually a giveaway to its premise. Aces and Faces, Jacks or Better, Joker Poker, etc. These names all let you know a little something about what is expected before you start.
The basis of Deuces Wild is fairly simple. There are four 2's in a standard deck of 52 cards. These four deuces are wild and can be used to substitute for any other card in order to complete a poker hand.
The objective is to finish the hand with a three of a kind or better in order to win any money back on your bet. The better you hand is after you receive your cards, the more money you will win on your bet.
When it comes to playing video poker, there isn't just one strategy that will help you play every game. The rules to each game are different, therefore the payouts will differ as well. Here is a page that is dedicated to only deuces wild strategy and advise.
