The minimum paying hand is the poker hand that players will have to achieve to be eligible to claim a payout. It differs from one game to another depending on the rules of the game as well as the other features. For example, if a game has a wild card or cards, it will have a higher minimum paying hand, which could be as high as 3 of a kind. This means that if players do not get a three of a kind, they will not qualify for a win. For a Jacks or Better, the minimum hand is a pair of Jacks. For Tens or Better, it is a pair of Jacks, but most games that do not have extra features, the minimum hand is a pair of Jacks.
Slot machines are extremely popular. One of the reasons for their popularity is that they are easy to play. The only skill that is necessary is to be able to insert money into the game and press a button or pull a lever to start play. That is it. From that point on, everything that happens depends on luck. The results of slot machine spins are based totally on randomness. The instant the slot player presses the spin button the result of that spin is locked in. Whether it is (most likely) a loser, a small winner, a moderate winner, or a jackpot winner has already been decided. Slot players can do nothing to change the odds either for or against them.
It contained the games that I was specifically looking for, which were Jacks or Better and Deuces Wild; but also contains a total of 23 different poker games - some of which I hadn't played before, but will play in the future after trying them out on WinPoker. I believe that it does have the majority of games included that you see at casinos: Bonus Poker, Double Bonus Poker, etc.
Video poker is a very volatile game, about four times as much as blackjack. In any form of gambling, short-term results mostly depend on normal mathematical randomness (what some might call luck). However, in the long run, results mostly depend on skill. If you play a game with a return of 100.76% perfectly, that does not mean that you will have a 0.76% profit every time you play. The 100.76% is an EXPECTED return. Much in the same way, if you flip a coin ten million times, the expected number of tails will be five million, but it is unlikely you will hit five million on the nose. Actual results will vary significantly from expectations, but the more you play, the closer your actual return percentage will get to the expected return.
