foursuit

Foursuit is a term used in various contexts related to a standard deck of playing cards in which four suits are present in play or emphasis. There is no single, widely accepted definition, and its meaning depends on the context.

In card games and probability, foursuit commonly describes a hand or position in which all four suits are represented. For example, in bridge analysis, players examine suit distribution patterns such as 4-4-3-2 or 4-3-3-3; the phrase may appear in informal discussions to indicate that all suits are active rather than a void in any suit.

In other settings, foursuit appears in hobbyist or fan-made card games or puzzle challenges that feature mechanics based on managing four separate suits or forming sequences within each suit, sometimes called a foursuit variant or foursuit puzzle.

In branding or online culture, Foursuit may be used as a product name, fictional faction, or username, independent of a card game meaning.

Because the term lacks a single canonical definition, readers should consult context-specific sources to determine its intended meaning in a given discussion. See also four-suit deck, suit distribution, bridge, and various card game variants for related concepts.
