Little is known about the exact origins of the music we now know as the blues.[ No specific year can be cited as the origin of the blues, largely because the style evolved over a long period of time and existed in something approaching its modern form before the term blues was introduced, before the style was thoroughly documented. One important early reference to something closely resembling the blues comes from 1901, when an archaeologist in Mississippi described the songs of black workers which had lyrical themes and technical elements in common with the blues. The most important direct antecedent of the blues was the spiritual, a form of religious song with its roots in the camp meetings of the Great Awakening of the early 19th century. Spirituals were a passionate song form, that "convey(ed) to listeners the same feeling of rootlessness and misery" as the blues.Spirituals, however, were less specifically concerning the performer, instead about the general loneliness of mankind, and were more figurative than direct in their lyrics. Despite these differences, the two forms are similar enough that they can not be easily separated — many spirituals would probably have been called blues had that word been in wide use at the time.

Card Game Rules

Any specific card game imposes restrictions on the number of players. The most significant dividing lines run between one-player games and two-player games, and between two-player games and multi-player games. Card games for one player are known as solitaire or patience card games.  Generally speaking, they are in many ways special and atypical, although some of them have given rise to two- or multi-player games such as Spite and Malice.

In card games for two players, usually not all cards are distributed to the players, as they would otherwise have perfect information about the game state. Two-player games have always been immensely popular and include some of the most significant card games such as piquet, bezique, sixty-six, klaberjass, gin rummy and cribbage. Many multi-player games started as two-player games that were adapted to a greater number of players. For such adaptations a number of non-obvious choices must be made beginning with the choice of a game orientation.

One way of extending a two-player game to more players is by building two teams of equal size. A common case is four players in two fixed partnerships, sitting crosswise as in whist and contract bridge. Partners sit opposite to each other and cannot see each other's hands. If communication between the partners is allowed at all, then it is usually restricted to a specific list of permitted signs and signals. 17th century French partnership games such as triomphe were special in that partners sat next to each other and were allowed to communicate freely so long as they did not exchange cards or played out of order.

Another way of extending a two-player game to more players is as a cut-throat game, in which all players fight on their own, and win or lose alone. Most cut-throat card games are round games, i.e. they can be played by any number of players starting from two or three, so long as there are enough cards for all.

For some of the most interesting games such as ombre, tarot and skat card game, the associations between players change from hand to hand. Ultimately players all play on their own, but for each hand, some game mechanism divides the players into two teams. Most typically these are solo games, i.e. games in which one player becomes the soloist and has to achieve some objective against the others, who form a team and win or lose all their points jointly. But in games for more than three players, there may also be a mechanism that selects two players who then have to play against the others.

Compulsive Gambling

Many people enjoy gambling, whether it's betting on a horse or playing poker on the Internet. Most people who gamble don't have a problem, but some lose control of their gambling. Signs of problem gambling include

Always thinking about gambling
Lying about gambling
Spending work or family time gambling
Feeling bad after you gamble, but not quitting
Gambling with money you need for other things

Many people can control their compulsive gambling with medicines and therapy. Support groups can also help.
Gambling addiction, also known as compulsive gambling, is a type of impulse-control disorder. Compulsive gamblers can’t control the impulse to gamble, even when they know their gambling is hurting themselves or their loved ones. Gambling is all they can think about and all they want to do, no matter the consequences. Compulsive gamblers keep gambling whether they’re up or down, broke or flush, happy or depressed. Even when they know the odds are against them, even when they can’t afford to lose, people with a gambling addiction can’t “stay off the bet.”

Chips Poker

Poker chips are fabricated with complicated graphics and edge spot patterns intending to make them difficult to counterfeit. The process used to make these poker chips is a trade secret and expensive - typically done on high pressure compression molding machines. The typical material of construction for poker chips is not clay as is sometimes believed, but a ceramic material with clay added for texture and weight. The breakable, clay poker chips of the 1960s and 1970s are no longer manufactured. The clay composition of modern chips varies by manufacturer, and is typically very slight (1-10%).

Casino poker chips are special tokens representing a fixed amount of money. The chips used in American Casinos generally weigh 10 grams each. The chips sold for home use vary much more, depending on manufacturer and construction.
