It is difficult to track in the time the origin of the poker. Nevertheless, the historians of the game mention a text, that dates from 1934, like one of the oldest references written on poker of which the news are had. This text maintains that, at the outset, the “cheating game” was called and details the rules of the poker. This game, popular in the boats of the Missisippi, still without an own name, is baptized as poker by the same Green.

Nevertheless, the reasons are not clear for which it used this word. Some historians of the game say that he comes from a French word, “poque”, that he named to a game of that nationality. Been born from " poque" French, or no, the game was changing and evolving. With time, he included 32 letters and, little by little, one went away at present reaching the amount of letters of the deck: 52. Nevertheless the evolution of this so popular game was not free of frights. For example, at the beginning of century XX, is declared it illegal in the state of Nevada, in the USA. But because the poker is considered plus an ability game that of chance, the authorities of California established that the norms against the chance games could not be applied to the poker, unless the call “Stud gambled Poker”, based exclusively on the chance.

At present, strict norms regulate the poker, as much in Internet as in real casinos. Since the more popular game of the world is considered letter, their matches and different competitions have gotten to constitute it like international a sport event. Although there are many interesting variants, in the USA, the three main ones are " Stud of 7 cartas" , " Texas Hold' member state Poker" and the call " 5 Card Draw". Also, nowadays, the variant of " can be added; Omaha" , that keeps similarities with Texas Hold´em. The discarding poker was very popular in century XIX; but at the beginning of century XX " acquires major importance; Stud of 7 cartas" (7 Stud Poker), and this was thus until the decade of 1970, when it began to be the variant that gambled in the international matches. The same students find difficult to imagine how they would have been the things if this had not been thus; that is to say, if still outside the one of more importance the discarding poker. But it is still more difficult to imagine how he would be everything if, in 1998, it had not appeared Texas Hold' member state, that introduced the idea to play without limit, something new for the great majority of the players of ten years back.
