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.
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.
You will also learn the layout and importance of the pay table, as well as how to properly bet while playing video poker. You will learn and understand payback, return, house (and player) edge. You will learn about the implications of variance, sometimes called volatility. You will also learn what the term random really means when playing video poker.
