Use a player card, and know the benefits of doing so. Casinos reward points for every penny bet in any machine, and those points can be redeemed for free play or comps. Free play rebates usually run from 0.1% to 0.33%. There are lots of other benefits for using a player card, like discretionary comps, free play mailers, drawings, and tournaments. If you don't use a card, there will be no evidence trail that you played, so you'll never get any of the freebies. This advice goes for any form of gambling. Finally, contrary to popular myth, the machines don't pay worse if you put in a card. The odds are the same whether you use a player card or not.
All possible resulting hands and pays for a hold of just the ace of hearts must be calculated. The same must then be done for a save of just the 3 of spades, the 4 of hearts, the 5 of clubs, and the king of diamonds. Then the same must be done for each possible hold of two cards. Then the same is done for holds of three cards. The same is done for holds of four cards. Finally the return for a hold of all five cards is calculated. The returns are then compared in order to select the best possible hold (in terms of money returned). The results for each of the over two and a half million possible hands are summarized in order to develop the strategy.
Since there are a lot of games that offer different paying hands, gamble features and wild cards, it is essential to check the rules and the paytable of the video poker game before you start playing. Knowing the minimum paying hand is quite important. The names of some video poker games might give you a clue, such as Tens or Better (a pair of tens is the minimum hand) and Jacks or Better (a pair of jacks is the minimum hand). For other games, it is essential to check the paytable and know the minimum paying hand because it will affect your decisions during the game.
But video poker adds something slot machines don't have -- an element of skill. Players have decisions to make that affect the outcome. And because cards are required to be dealt from a randomly shuffled 52-card deck -- or 53 cards, in the case of Joker's Wild machines -- the possible combinations are known, the frequency of the combinations can be calculated, and an optimal playing strategy can be devised. In fact, when Missouri riverboats opened under a law that forbade games of chance, casinos were allowed to offer video poker, as a game of skill, even though slots, as games of chance, had to wait until voters changed the law.
The strategy below is the Wizard's simplified strategy for Jacks or Better. You give up just a tiny part of the return (99.46% instead of 99.54%) and in exchange you get a strategy that's much, much easier to learn and remember than the perfect strategy. The 0.08% penalty costs you only $0.60 per hour of play on average, assuming a quarter machine played at 600 hands per hour.
You may have heard the adage that the "house always has the advantage." Video poker is an exception to that rule. If you look for the most liberal pay tables, and play them properly, you can have a thin advantage. Some pay tables, which are slightly in the machine's favor, can return over 100%, if you factor in incentives such as cash back, free play, mailers, and other comps.
