A note on gambling with cards
Card games played for money are games of chance and, often, skill, but in the casino they come with a built-in house edge. No strategy, system or timing changes the odds in the player’s favor over time, most players lose money in the long run, and nobody should gamble money they cannot afford to lose. A local support service can help anyone struggling with gambling.
Where cards came from
Historians generally place the earliest playing cards in East Asia, with China the most commonly cited origin, sometime in the first millennium or around the turn of the second. The exact date and form are uncertain. Early items may have been paper tokens or “money cards” connected with gambling and dominoes, and the evidence is fragmentary, so claims of a precise year should be treated with caution.
From Asia, cards appear to have traveled westward through the Islamic world. Surviving decks from the Mamluk area, in the Middle East, are among the best-known early examples. They had suits that included cups, coins, swords and polo sticks, a set that resembles the suit systems later seen in Southern Europe.
Arrival in Europe
Playing cards are documented in Europe from the late 1300s. Records from several places, including Spain, Italy, France and German-speaking lands, mention cards at around that time, and some authorities soon restricted them, which suggests they were already popular and used for gambling. Early European decks were hand-painted and costly, which limited who could own them.
Different regions developed their own suit systems:
- Italian and Spanish decks used swords, batons (or clubs), cups and coins.
- German-speaking regions used hearts, leaves, acorns and bells.
- France developed spades, hearts, diamonds and clubs, which were easy to reproduce with stencils.
The French suits spread widely, including to England and later North America. Their simple shapes made printing cheaper and faster. The names “spades”, “clubs”, “hearts” and “diamonds” reflect this mix of origins and translations rather than a single design plan.
Printing and the standard deck
The development of woodblock printing, and later of the printing press and engraving, made cards cheap enough to be common. Cards then became a mass product, and governments in some countries began taxing them, which is why some old decks carry a stamp.
The 52-card deck with four suits of thirteen ranks became the usual pack in English-speaking countries. Its count is simple arithmetic: 4 suits times 13 ranks is 52. Other decks differ. Some traditional packs have 32 or 40 cards, and tarot-style decks have more. The joker, a later addition, is often traced to 19th-century America, where it was introduced for a particular card game; it is not a standard part of casino decks in most games.
Another design change was the double-ended court card, with a mirrored image, and the addition of index numbers in the corners so cards could be read when held in a fan. The latter is a practical feature that made card games easier to play.
From parlor games to gambling games
Many card games began as social or trick-taking games, and gambling grew up around them. Some examples, with the usual caveats about origins:
- Blackjack. Its ancestors are often traced to French and Spanish games of the 1700s, including one called vingt-et-un (twenty-one). It became popular in American gambling houses in the 1800s and 1900s. The strategic details and card counting belong to the blackjack mathematics articles.
- Poker. Poker is generally described as developing in the United States in the early 1800s, possibly influenced by earlier European games, though the origins are contested. Hand rankings and the combinatorics behind them are examined separately.
- Baccarat. It is usually described as having Italian or French roots and was popular in European gambling houses. Today it is a casino staple, with banker and player bets.
Card games also gave probability theory some early problems, because counting combinations of cards is a natural exercise. Modern treatments of card combinations build on that tradition.
Cards in the casino
In a casino, a standard deck is dealt by hand or from a shoe containing multiple decks, depending on the game. Because the cards themselves can be tampered with, marked or counted, casinos developed procedures including surveillance, regular deck changes and shuffling machines. These were partly responses to the history of casino cheating.
Cards have also moved online. Software cannot shuffle a physical deck, so online card games use a random number generator to simulate a shuffle, while live dealer games stream a real deck. In both formats, each hand is an independent event, and past cards do not change the odds on a freshly shuffled deck.
Summary
Playing cards traveled across continents over many centuries, adapting their suits, sizes and uses as they went. Their gambling uses are long-standing, but they sit alongside everyday games played for no stakes at all. For casino card games, the key point remains the rules and payouts of the specific game, which determine the cost of playing.
