Unlike traditional slot machines, video poker is THE ONLY game where the pay table clearly indicates the return on your gambling dollar, based on your ability to play mathematically correctly. By practicing your favorite game for free at home, you can learn to play perfectly. Not only can you win more money, but you can also enjoy wining, dining and entertainment set aside for the casino's best players.
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.
