Playing cards in the context of "Mahjong solitaire"

Card stock, also called cover stock and pasteboard, is paper that is thicker and more durable than normal writing and printing paper, but thinner and more flexible than other forms of paperboard.

Card stock is often used for business cards, postcards, playing cards, catalogue covers, scrapbooking, and other applications requiring more durability than regular paper gives. The surface usually is smooth; it may be textured, metallic, or glossy. When card stock is labeled cover stock, it often has a glossy coating on one or both sides (C1S or C2S, for "coated: one side" or "coated: two sides"); this is used especially in business cards and book covers.

Tarot (/ˈtæroʊ/, first known as trionfi and later as tarocchi or tarocks) is a set of playing cards used in tarot games and in fortune-telling or divination. From at least the mid-15th century, the tarot was used to play trick-taking card games such as Tarocchini. From their Italian roots, tarot games spread to most of Europe, evolving into new forms including German Grosstarok and modern examples such as French Tarot and Austrian Königrufen.

Tarot is commonly found in many countries, especially in English and Spanish speaking countries where tarot games are not as widely played, in the form of specially designed cartomantic decks used primarily for tarot card reading, in which each card corresponds to an assigned archetype or interpretation for divination, fortune-telling or for other non-gaming uses.

A quincunx (/ˈkwɪn.kʌŋks/ KWIN-kunks) is a geometric pattern consisting of five points arranged in a cross, with four of them forming a square or rectangle and a fifth at its center. The same pattern has other names, including "in saltire" or "in cross" in heraldry (depending on the orientation of the outer square), the five-point stencil in numerical analysis, and the five dots tattoo. It forms the arrangement of five units in the pattern corresponding to the five-spot on six-sided dice, playing cards, and dominoes. It is represented in Unicode as U+2059 ⁙ FIVE DOT PUNCTUATION or (for the die pattern) U+2684 ⚄ DIE FACE-5.

A spoke card, or spokecard, is a card placed in the spokes of a bicycle wheel. They lie parallel to the entire wheel. Most spoke cards are laminated.

Throughout the 20th century, playing cards were placed in such a way as to make a noise as the card flaps against the spokes; however, there is no evidence that these were called "spoke cards."

Laminar flow (/ˈlæmɪnər/) is the property of fluid particles in fluid dynamics to follow smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another smoothly. There are no cross-currents perpendicular to the direction of flow, nor eddies or swirls of fluids. In laminar flow, the motion of the particles of the fluid is very orderly with particles close to a solid surface moving in straight lines parallel to that surface.Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection.

When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow occurs at lower velocities, below a threshold at which the flow becomes turbulent. The threshold velocity is determined by a dimensionless parameter characterizing the flow called the Reynolds number, which also depends on the viscosity and density of the fluid and dimensions of the channel. Turbulent flow is a less orderly flow regime that is characterized by eddies or small packets of fluid particles, which result in lateral mixing. In non-scientific terms, laminar flow is smooth, while turbulent flow is rough.

Rummy is a group of games related by the feature of matching cards of the same rank or sequence and same suit. The basic goal in any form of rummy is to build melds which can be either sets (three or four of a kind of the same rank) or runs (three or more sequential cards of the same suit) and either be first to go out or to amass more points than the opposition.

French-suited playing cards or French-suited cards are cards that use the French suits of trèfles (clovers or clubs ♣), carreaux (tiles or diamonds ♦), cœurs (hearts ♥), and piques (pikes or spades ♠). Each suit contains three or four face/court cards. In a standard 52-card deck these are the valet (knave or jack), the dame (lady or queen), and the roi (king). In addition, in Tarot packs, there is a cavalier (knight) ranking between the queen and the jack. Aside from these aspects, decks can include a wide variety of regional and national patterns, which often have different deck sizes. In comparison to Spanish, Italian, German, and Swiss playing cards, French cards are the most widespread due to the geopolitical, commercial, and cultural influence of France, the United Kingdom, and the United States in the 19th and 20th centuries. Other reasons for their popularity were the simplicity of the suit insignia, which simplifies mass production, and the popularity of whist and contract bridge. The Anglo-Saxon pattern of French-suited cards is so widespread that it is also known as the International or Anglo-American pattern.
