Si Redd’s Coin Machines, also known as SIRCOMA, released its version of Draw Poker in 1979. The significance of that statement may be increased with the news that SIRCOMA eventually went on to become International Game Technology (IGT). It was a huge hit. One of the reasons credited to the popularity of video poker and slots was how easy it was to learn how to play them. This was long before the huge presence of online video poker and other casino games we have today. Many customers were intimidated by brick-and-mortar casinos. These machines offered a new way to play, without any pressure.
Unlike slot machines, video poker games allow players to have a say in the game they chose to play. Like slot machines, randomness is also involved. The instant the “Bet Max Credits” or the “Deal / Draw” button is pressed the five cards to be dealt are determined based on a random process. After the cards to be held are selected by the video poker player, the cards that replace those not held are also determined by a random process at the instant the “Deal/Draw” button is pressed.
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.
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.
