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.
Despite the importance of finding the best machines, most players don't. That's why casinos can offer both decent and lousy machines in the same casino and be confident that gamers will still play the lousy ones. They have to keep some good machines, otherwise they'd lose all the players who know what they're doing. But most of the machines will be bad, and most gamers will play them anyway. Heck, in Vegas even casinos and supermarkets have video poker, with absolutely terrible paytables, but people will still play them rather than going across the street to a casino where they can get seven times better odds. Go figure.
Winning a slot machine jackpot is based solely on luck. You put your money in the machine, hit the spin button and hope that Lady Luck will invite you to dance. There are no decisions to make that will change the outcome of the spin. On the other hand, many table games require skill and the decisions you make can determine whether you win or lose. Most table games when played properly have a lower house edge than the slot machines. Knowledgeable Blackjack players know that learning basic strategy will reduce the house edge to less than one percent.
