A betting pool, sports lottery, sweep or office pool if done at work, is a form of gambling, specifically a variant of parimutuel betting influenced by lotteries, where gamblers pay a fixed price into a pool from which taxes and a house take or vig are removed, and then make a selection on some outcome, usually related to sport. In an informal game, the vig is usually quite small or non-existent. The pool is evenly divided between those that have made the correct selection. There are no odds involved; each winner's payoff depends simply on the number of gamblers and the number of winners. True parimutuel betting, which was historically referred to as pool betting, involves both odds calculations and variable wager amounts. Contestants predict the outcome of sporting events that take place at a later time. The concept was introduced in 1923 by Littlewoods Pools where it was known as totoclarification needed and based on football soccer matches. Today in England, sports lotteries are more commonly referred to as football pools. American sports lotteries often do not require contestants to purchase a lottery ticket or make an initial wager. Hockey pools are common in North America, and footy tipping in Australia.

History of Poker

The history of poker is a matter of some debate. The name of the game likely descended from the French poque, which descended from the German pochen ('to knock'), but it is not clear whether the origins of poker itself lie with the games bearing those names. It closely resembles the Persian game of as nas, and may have been taught to French settlers in New Orleans by Persian sailors. It is commonly regarded as sharing ancestry with the Renaissance game of primero and the French brelan. The English game brag (earlier bragg) clearly descended from brelan and incorporated bluffing (though the concept was known in other games by that time). It is quite possible that all of these earlier games influenced the development of poker as it exists now.

English actor Joseph Crowell reported that the game was played in New Orleans in 1829, with a deck of 20 cards, four players betting on which player's hand was the most valuable. Jonathan H. Green's book, An Exposure of the Arts and Miseries of Gambling (G. B. Zieber, Philadelphia, 1843), described the spread of the game from there to the rest of the country by Mississippi riverboats, on which gambling was a common pastime.

During the American Civil War, many additions were made, including draw poker, stud poker (the five-card variant), and the straight. Further American developments followed, such as the wild card (around 1875), lowball and split-pot poker (around 1900), and community card poker games (around 1925). Spread of the game to other countries, particularly in Asia, is often attributed to the U.S. military.

The game and jargon of poker have become important parts of American culture and English culture. Such phrases as ace in the hole, ace up one's sleeve, beats me, blue chip, call one's bluff, cash in, high roller, pass the buck, poker face, stack up, up the ante, when the chips are down, wild card, and others are used in everyday conversation even by those unaware of their origins at the poker table.

Modern tournament play became popular in American casinos after the World Series of Poker began in 1970. It was also during that decade that the first serious strategy books appeared, notably The Theory of Poker by David Sklansky, Super System by Doyle Brunson (ISBN 0931444014), and The Book of Tells by Mike Caro .

Poker’s popularity has experienced an unprecedented spike in recent years, largely due to the introduction of online poker and the invention of the hole-card camera which finally turned the game into a spectator sport. Viewers can now follow the action and drama of the game, and broadcasts of poker tournaments such as the World Series of Poker and the World Poker Tour have brought in huge audiences for cable and satellite TV distributors.
