In video poker, just like regular poker, you will be given five cards. With those five cards you'll want to achieve a winning poker hand (royal flush, straight, full house, flush, four of a kind, three of a kind, two pair, jacks or better). To do this, you'll have the opportunity to keep certain cards in your hand and exchange others to gain new cards that may help you gain a winning poker hand.
This is well worth the price. It helped me to improve my game within the first day of playing (One example: did you know that if you are dealt 2 pairs in Deuces Wild, you should keep only 1 of the pairs and draw 3 cards? You are better off to go for 3-of-a-kind or even 4-of-a-kind than trying for the Full House). It can let you know when you make a mistake, and analyze your play for each game with percentage of correct plays, how much you would have won/lost if you had made all correct plays, and other information.
Joining the slot club will give you additional rewards for all of your play so it is well worthwhile since you would be playing anyway. Setting a budget is a crucial step as you should only ever gamble with money you can afford to lose. You should also expect that even with the best possible pay tables you will not win on every session you play - that's why it's called gambling.
Once I hit two 4 of a Kinds back to back. The probability of hitting it once is 0.24%. The chances of hitting it back to back are 0.24%2 = 0.0006%, or 1 in 179,000. That's four times less likely than hitting a royal flush. And I would have preferred the royal! (By the way, purists will note that after you've hit a 4 of a Kind, the chances of hitting another four of a kind is just 0.24%, not 0.0006%, but I'm considering the probability of getting two back-to-back before I get the first one.)
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.
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.
