10 Fun Facts About Playing Cards You Probably Didn’t Know

Main Content

1. The Ancient Origins of Playing Cards

Playing cards date back to 9th-century China, where the earliest card games were played during the Tang Dynasty. They later spread to the Middle East and Europe, evolving into the modern deck we know today. The French standardized the four suits—spades, hearts, diamonds, and clubs—in the 15th century.

2. The Kings on Playing Cards Represent Real Historical Figures

Each King (K) in a deck of cards is based on a real historical ruler:

• King of Spades: King David (Biblical ruler of Israel)

• King of Hearts: Charlemagne (Emperor of the Holy Roman Empire)

• King of Diamonds: Julius Caesar (Roman dictator)

• King of Clubs: Alexander the Great (Macedonian conqueror)

Interestingly, the King of Hearts is the only king without a mustache and is sometimes called the "suicide king" because his sword points toward his head.

3. Why Is the Ace the Highest Card?

Originally, the Ace (A) was the lowest card in many games. However, after the French Revolution, the Ace was promoted to the highest rank as a symbol of the common people rising above royalty—a tradition still used in games like poker today.

4. Playing Cards Are Secretly a Calendar

A standard deck of 52 cards holds a hidden connection to time:

• 52 cards = 52 weeks in a year

• 4 suits = 4 seasons

• 12 face cards (Jacks, Queens, Kings) = 12 months

• Total pips (1+2+…+13) × 4 suits = 364, and adding the Joker makes 365—matching the days in a year!

• 5. The Joker Wasn’t Always Part of the Deck

  The Joker was introduced in the 19th century for the American game Euchre, where it served as the highest trump card. Later, it became a wild card in poker and other games. Some decks even include two Jokers, representing day and night.

  A deck of 52 cards can be arranged in 52! (52 factorial) possible ways—a number so large (8×10^67) that it’s more than all the atoms on Earth! This means every properly shuffled deck is likely unique in history.
