Shuffling Algorithm
Shuffling is a procedure used to randomize a deck of playing cards to provide an element of chance in card games. Shuffling is often followed by a cut, to help ensure that the shuffler has not manipulated the outcome. __TOC__ Techniques Overhand One of the easiest shuffles to accomplish after a little practice is the overhand shuffle. Johan Jonasson wrote, "The overhand shuffle... is the shuffling technique where you gradually transfer the deck from, say, your right hand to your left hand by sliding off small packets from the top of the deck with your thumb." In detail as normally performed, with the pack initially held in the left hand (say), most of the cards are grasped as a group from the bottom of the pack between the thumb and fingers of the right hand and lifted clear of the small group that remains in the left hand. Small packets are then released from the right hand a packet at a time so that they drop on the top of the pack accumulating in the left hand. The process ...

Zipper
A zipper, zip, fly, or zip fastener, formerly known as a clasp locker, is a commonly used device for binding together two edges of textile, fabric or other flexible material. Used in clothing (e.g. jackets and jeans), luggage and other Bag, bags, camping gear (e.g. tents and sleeping bags), and many other items, zippers come in a wide range of sizes, shapes, and colors. Whitcomb L. Judson, an American inventor from Chicago, in 1892 patented the original design from which the modern device evolved. Description A zipper consists of a slider mounted on two rows of metal or plastic teeth that are designed to interlock and thereby join the material to which the rows are attached. The slider, usually operated by hand, contains a Y-shaped channel that, by moving along the rows of teeth, meshes or separates them, depending on the direction of the slider's movement. The teeth may be individually discrete or shaped from a continuous coil, and are also referred to as ''elements''. The wor ...

Orders Of Magnitude (numbers)
This list contains selected positive numbers in increasing order, including counts of things, dimensionless quantities and probabilities. Each number is given a name in the short scale, which is used in English-speaking countries, as well as a name in the long scale, which is used in some of the countries that do not have English as their national language. Smaller than (one googolth) * ''Mathematics – random selections:'' Approximately is a rough first estimate of the probability that a typing "monkey", or an English-illiterate typing robot, when placed in front of a typewriter, will type out William Shakespeare's play ''Hamlet'' as its first set of inputs, on the precondition it typed the needed number of characters.

Names Of Large Numbers
Two naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales. Most English variants use the short scale today, but the long scale remains dominant in many non-English-speaking areas, including continental Europe and Spanish-speaking countries in Latin America. These naming procedures are based on taking the number ''n'' occurring in 103''n''+3 (short scale) or 106''n'' (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix ''-illion''. Names of numbers above a trillion are rarely used in practice; such large numbers have practical usage primarily in the scientific domain, where powers of ten are expressed as ''10'' with a numeric superscript. Indian English does not use millions, but has its own system of large numbers including lakhs and crores. English also has many words, such as "zillion", used informally to mean large but unspecified amoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
52-card Deck
The standard 52-card deck of French-suited playing cards is the most common pack of playing cards used today. In English-speaking countries it is the only traditional pack used for playing cards; in many countries of the world, however, it is used alongside other traditional, often older, standard packs with different suit systems such as those with German-, Italian-, Spanish- or Swiss suits. The most common pattern of French-suited cards worldwide and the only one commonly available in Britain and the United States is the English pattern pack. The second most common is the Belgian-Genoese pattern, designed in France, but whose use spread to Spain, Italy, the Ottoman Empire, the Balkans and much of North Africa and the Middle East.''Pattern Sheet 80'' at i-p-c-s.org.

Factorial
In mathematics, the factorial of a non-negative denoted is the product of all positive integers less than or equal The factorial also equals the product of n with the next smaller factorial: \begin n! &= n \times (n-1) \times (n-2) \times (n-3) \times \cdots \times 3 \times 2 \times 1 \\ &= n\times(n-1)!\\ \end For example, 5! = 5\times 4! = 5 \times 4 \times 3 \times 2 \times 1 = 120. The value of 0! is 1, according to the convention for an empty product. Factorials have been discovered in several ancient cultures, notably in Indian mathematics in the canonical works of Jain literature, and by Jewish mystics in the Talmudic book '' Sefer Yetzirah''. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, where its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there In mathematical analysis, factorials are used in power series for the exponential function an ...

Baccarat (card Game)
Baccarat or baccara (; ) is a card game played at casinos. It is a comparing card game played between two hands, the "player" and the "banker". Each baccarat coup (round of play) has three possible outcomes: "player" (player has the higher score), "banker", and "tie". There are three popular variants of the game: ''punto banco'', ''baccarat chemin de fer'',"Baccarat" in ''Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 2, pp. 32-33. and ''baccarat banque'' (or ''à deux tableaux''). In ''punto banco'', each player's moves are forced by the cards the player is dealt. In ''baccarat chemin de fer'' and ''baccarat banque'', by contrast, both players can make choices. The winning odds are in favour of the bank, with a house edge of at least 1 percent. History The origins of the game are disputed, and some sources claim that it dates to the 19th century. Other sources claim that the game was introduced into France from Italy at the end of the 15th century by soldiers re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Croupier
A croupier or dealer is someone appointed at a gambling table to assist in the conduct of the game, especially in the distribution of bets and payouts. Croupiers are typically employed by casinos. Origin of the word Originally a "croupier" meant one who stood behind a gambler, with extra reserves of cash to back him up during a gambling session. The word derived from ''croupe'' (the rump of a horse) and was by way of analogy to one who rode behind on horseback. It later came to refer to one who was employed to collect the money from a gaming-table. Originally a "dealer" meant one who was responsible for distributing cards or the player in the dealer position, regardless of whether or not that player was responsible for distributing the cards. Training Training methods to become a casino croupier vary from country to country. In North America, blackjack is almost always the game that dealers learn first, as it is simple and popular, and when the dealer makes errors, they tend ...

Shuffling Machine
A shuffling machine is a machine for randomly shuffling packs of playing cards. Because standard shuffling techniques are seen as weak, and in order to avoid "inside jobs" where employees collaborate with gamblers by performing inadequate shuffles, many casinos employ automatic shuffling machines to shuffle the cards before dealing. These machines are also used to reduce repetitive motion stress injuries to a dealer. Shuffling machines have to be carefully designed, as they can generate biased shuffles otherwise: the most recent shuffling machines are computer-controlled. The randomness or otherwise of cards produced from automatic shuffling machines is the subject of considerable interest to both gamblers and casinos. Shuffling machines come in two main varieties: continuous shuffling machines (CSMs), which shuffle one or more packs continuously, and batch shufflers or automatic shuffling machines (ASMs), which shuffle an entire single pack in a single operation.

Casino
A casino is a facility for certain types of gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shopping, cruise ships, and other tourist attractions. Some casinos are also known for hosting live entertainment, such as stand-up comedy, concerts, and sports. and usage ''Casino'' is of Italian origin; the root means a house. The term ''casino'' may mean a small country villa, summerhouse, or social club. During the 19th century, ''casino'' came to include other public buildings where pleasurable activities took place; such edifices were usually built on the grounds of a larger Italian villa or palazzo, and were used to host civic town functions, including dancing, gambling, music listening, and sports. Examples in Italy include Villa Farnese and Villa Giulia, and in the US the Newport Casino in Newport, Rhode Island.

Zarrow Shuffle
Zarrow shuffle is a sleight of hand technique that gives the appearance of being a normal riffle shuffle, but in fact leaves the cards in exactly the same order. This is an example of a false shuffle. It was invented by magician Herb Zarrow c. 1940. The sleight begins as a normal riffle shuffle, but the performer uses the top card of the deck to conceal the shuffle being cancelled by way of unweaving the cards.

Card Sharp
A card sharp (also cardsharp, card shark or cardshark, sometimes hyphenated) is a person who uses skill and/or deception to win at poker or other card games. "Sharp" and "shark" spellings have varied over time and by region. The label is not always intended as pejorative, and is sometimes used to refer to practitioners of card tricks for entertainment purposes. In general usage, principally in American English and more commonly with the "shark" spelling, the term has also taken on the meaning of an expert card gambler who takes advantage of less-skilled players, also called an "advantage player", without any implication of actual cheating at cards, in much the same way that "" or "pool hustler" can (especially when used by non-players) be intended to refer to a skilled player rather than a cheater or swindler. The synonym to "card sharp", "", when used with reference to card-playing and swindlers, has pejorative connotations. A card sharp or shark (by either of the gamb ...
