Standard 52-card Deck
The standard 52-card deck of French-suited playing cards is the most common pack of playing cards used today. The main feature of most playing card decks that empower their use in diverse games and other activities is their double-sided design, where one side, usually bearing a colourful or complex pattern, is exactly identical on all playing cards, thus ensuring the anonymity and fungibility of the cards when their value is to be kept secret, and a second side, that, when apparent, is unique to every individual card in a deck, usually bearing a suit as well as an alphanumerical value, which may be used to distinguish the card in game mechanics. In English-speaking countries it is the only traditional pack used for playing cards; in many countries, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Playing Cards Collage
Play is a range of intrinsically motivated activities done for recreation. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds. Play is often interpreted as frivolous; yet the player can be intently focused on their objective, particularly when play is structured and goal-oriented, as in a game. Accordingly, play can range from relaxed, free-spirited, spontaneous, and frivolous to planned or even compulsive. Play is not just a pastime activity; it has the potential to serve as an important tool in numerous aspects of daily life for adolescents, adults, and cognitively advanced non-human species (such as primates). Not only does play promote and aid in physical development (such as hand-eye coordination), but it also aids in cognitive development and social skills, and can even act as a stepping stone into the world of integration, whic ...

Suit (cards)
In playing cards, a suit is one of the categories into which the cards of a deck are divided. Most often, each card bears one of several pips (symbols) showing to which suit it belongs; the suit may alternatively or additionally be indicated by the color printed on the card. The rank for each card is determined by the number of pips on it, except on face cards. Ranking indicates which cards within a suit are better, higher or more valuable than others, whereas there is no order between the suits unless defined in the rules of a specific card game. In most decks, there is exactly one card of any given rank in any given suit. A deck may include special cards that belong to no suit, often called jokers. While English-speaking countries traditionally use cards with the French suits of Clubs, Spades, Hearts and Diamonds, many other countries have their own traditional suits. Much of central Europe uses German suited cards with suits of Acorns (Clubs), Leaves (Spades), Hear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Permutation
In mathematics, a permutation of a set can mean one of two different things: * an arrangement of its members in a sequence or linear order, or * the act or process of changing the linear order of an ordered set. An example of the first meaning is the six permutations (orderings) of the set : written as tuples, they are (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). Anagrams of a word whose letters are all different are also permutations: the letters are already ordered in the original word, and the anagram reorders them. The study of permutations of finite sets is an important topic in combinatorics and group theory. Permutations are used in almost every branch of mathematics and in many other fields of science. In computer science, they are used for analyzing sorting algorithms; in quantum physics, for describing states of particles; and in biology, for describing RNA sequences. The number of permutations of distinct objects is factorial, us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Factorial
In mathematics, the factorial of a non-negative denoted is the Product (mathematics), 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 ex ...

The trull is a trio of three special trump (cards), trump cards used in Tarock (card games), tarock games in Austria and other countries that have a much higher card value than the other trumps. The individual cards are known as trull cards (''Trullstücke''). The word ''trull'' is derived from the French ''tous les trois'' which means "all three". In spite of its French roots the term is not common in the game of French tarot, where the trull cards are called ''les bouts'' ("butts", "ends") or, in earlier times, ''les oudlers'', which has no other meaning. In German, they were initially called ''matadors'', a word borrowed from the game (with ordinary cards) of Ombre. Introduction The games of the tarot card games, tarot (French) or Tarock (card games), tarock (German) family are distinguished mainly in that, in addition to the suit cards, their decks have a series of 21 classical, permanent trump (cards), trumps, most of which are numbered with Roman numerals, Roman or Arabi ...
