kartludoj

Kartludoj, in Esperanto, refers to games played with a deck of playing cards. The term encompasses a wide range of activities, from casual family games to formal competitions. Card games can be played by single players (solitaire) or by groups, and they may emphasize luck, skill, or a combination of both. Equipment typically includes one or more standard 52-card decks, possibly with jokers or special decks.

History: Playing cards emerged in East Asia, spread to the Middle East and Europe by the late medieval period. Over centuries, players developed distinct rules and genres, producing hundreds of games. The standard 52-card deck became widespread in Europe in the 19th century and is now used globally; regional decks and variants also persist.

Categories and mechanics: Card games are commonly grouped into trick-taking games (where players play cards to win rounds and collect points or tricks, e.g., Bridge, Hearts, Spades), matching or memory games (concentration, where pattern matching or memory determines progress), set-building or melding games (the Rummy family, Canasta), and shedding or climbing games (where players discard cards to reach a target). Solitaire is a separate single-player category. Many games combine bidding, partnerships, and scoring systems.

Examples and popularity: Bridge is a long-standing competitive game with formal bidding; Hearts and Spades are widely played trick-taking games; Gin Rummy and Canasta are popular matching and melding games; solitaire variants are common on computers and mobile devices.

Cultural and digital presence: Card games are common in households, clubs, and online platforms; they support social interaction and strategic thinking. Tournament circuits exist for several genres, including bridge and various online card games.
