The History of Craps: From Ancient Dice to America's Iconic Casino Game

Where does craps come from?

Craps is the modern descendant of an older English dice game called Hazard, which arrived in Europe centuries earlier and was simplified into its current form in 19th-century America. But the deeper roots of craps run all the way back to the very first dice ever made.

Dice are among humanity's oldest gaming tools. Long before craps, people gambled with knucklebones — the small ankle bones of sheep and goats, called astragali — which were thrown and read much like dice. Carved six-sided dice appear in archaeological sites across the ancient Near East, Egypt, and the Roman world. The impulse to bet on a roll is genuinely ancient; craps is simply the most refined survivor of that very old human habit.

What was Hazard, the medieval ancestor of craps?

Hazard was a complex two-dice gambling game, popular in medieval and early-modern England, that is the direct ancestor of craps. Its very name reveals its origins: "hazard" comes from the Arabic az-zahr, meaning "the die." The game is widely believed to have entered Europe through contact between Crusaders and the Arabic-speaking world.

Anglo-Norman references to a dice game called hasard or hazart appear in the late 12th and early 13th centuries, with one tradition holding that English soldiers learned it from their opponents during the Third Crusade (1189–1192). A colorful but unreliable legend even attributes the game to Sir William of Tyre and his knights around 1125, supposedly named after a castle called "Hazarth" they were besieging — a story historians treat as folklore rather than fact.

What is certain is that Hazard became deeply woven into English culture. Geoffrey Chaucer referenced dice gambling in The Canterbury Tales (c. 1390), most memorably in "The Pardoner's Tale," where three young gamblers' obsession with dice leads them to ruin. By the 17th and 18th centuries, despite famously complicated rules, Hazard was a fashionable game played for money in gambling houses across England.

How was Hazard actually played?

In Hazard, a player called the "caster" chose a target number and then rolled to win, lose, or establish a second number they had to hit before losing — a structure that survives almost intact in modern craps. Understanding Hazard makes the logic of craps instantly clear.

The caster (also called the shooter) would name a "main" number, typically between 5 and 9. They then threw two dice, with several possible outcomes:

• Rolling the main immediately won the round (a "nick" or "throwing in").
• Rolling certain numbers — such as a 2 or 3 — immediately lost (an "out" or "throwing out").
• Rolling another number established a "chance," which the caster then had to roll again before rolling the main in order to win.

If you recognize that pattern — a first decisive roll, then a "point" number you chase before you lose — you already understand the heart of craps. The modern come-out roll and point phase are a streamlined version of Hazard's main-and-chance system.

Who brought craps to America?

The transformation of Hazard into craps is traditionally credited to Bernard de Marigny, a wealthy young Creole aristocrat who introduced and popularized a simplified version of the game in New Orleans in the early 1800s.

Jean-Bernard Xavier Philippe de Marigny de Mandeville was one of the richest men in Louisiana, a famous gambler who had spent time in London — where Hazard was in vogue. Arriving back in New Orleans around 1805, he is said to have stripped Hazard down to a simpler, faster game that fixed the main number at 7, which he recognized as the most statistically likely roll with two dice.

This simplification made the game more accessible to the diverse population of early-19th-century New Orleans. The game soon escaped the private gambling rooms of the Creole elite and spilled into the streets, where players crouched against walls, curbs, and sidewalks to roll — a vivid image that, as we'll see, may have given the game its very name.

(It's worth noting that historians debate how much of the de Marigny story is literal fact versus tradition. The broad outline — Hazard simplified in New Orleans in the early 1800s — is well established, but de Marigny's exact personal role has acquired some legend over two centuries of retelling.)

Why is craps called "craps"? The name debate

The name "craps" most likely comes from "crabs," the term in Hazard for a losing low roll — though a competing theory traces it to the French word crapaud, meaning "toad." This is one of the most-debated questions in gambling history, and both explanations have real support.

The "crabs" theory (more widely accepted): In Hazard, the lowest, losing throw — a roll of two, what we'd now call "snake eyes" — was called "crabs." As the game passed from English into the Louisiana French dialect and back into English again, "crabs" plausibly shifted in pronunciation to "craps." Etymologists tend to favor this route.

The crapaud (toad) theory: In New Orleans, the game was reportedly known as crapaud, French for "toad" — a nod to the way street players squatted low over the dice, looking toad-like as they crouched against the curb. It's a memorable image, and the French-language environment of New Orleans makes it linguistically plausible.

Both theories agree on the essentials: the name was fixed in New Orleans, in a French-speaking milieu, in the early 19th century. The truth may even be a blend of the two.

How did John H. Winn modernize craps?

The single most important figure in modern craps is John H. Winn, an American dice maker who, around 1907, fixed a critical flaw in the game and invented the betting structure used in casinos today. If de Marigny gave craps its form, Winn gave it its fairness.

De Marigny's simplified game had a serious problem: its rules gave players a built-in edge over the house and, crucially, were easy to exploit with fixed or loaded dice. A cheater using crooked dice could reliably beat the game, which made it dangerous for honest operators and players alike.

Winn's breakthrough was elegant. He introduced the option to bet "Don't Pass" — that is, to wager with the house, betting that the shooter would lose. Because players could now bet on either side of the dice, no one could profit simply by using dice loaded to favor one outcome; betting against the shooter neutralized the cheat. Winn also refined the table layout to support this two-sided betting.

This innovation — often dated to 1907 — is the foundation of "bank craps," the version played in every modern casino. The Pass Line, the Don't Pass bar, and the balanced betting layout all trace directly to Winn's fix. He is rightly remembered as the "Father of Modern Craps."

What about Monte Carlo and the European casinos?

Here is a crucial and often-misunderstood point: craps is fundamentally an American game, and the legendary European casinos — above all Monte Carlo — built their fame on roulette and baccarat, not on dice. If you picture craps tables in 19th-century Monaco, you're picturing the wrong game.

The Casino de Monte-Carlo opened in 1863 in Monaco, championed by the ruling Grimaldi family to rescue the principality from near-bankruptcy and run by the brilliant casino operator François Blanc, who had made his name at Bad Homburg in Germany. Blanc built hotels, roads, and a railway line to bring wealthy Europeans to the tiny state. The gamble worked spectacularly: casino revenues soared, and Monaco abolished income tax in 1869 on the strength of gaming profits, transforming itself from a poor territory into a byword for luxury.

But the game that powered Monte Carlo's golden age was single-zero European roulette, which dominated the floor from 1863 into the 1900s, alongside card games like baccarat (chemin de fer / punto banco). These — not craps — are the games woven into the legend of Monte Carlo, immortalized in stories of players "breaking the bank." While craps was being simplified in the streets of New Orleans and would later be perfected by John H. Winn in America, the European gambling tradition followed a completely separate path centered on the wheel and the cards.

So where does craps fit in Monte Carlo? Craps is offered at the Casino de Monte-Carlo today — it appears on modern gaming menus alongside roulette, blackjack, punto banco, and poker — but it arrived as a later, largely American import rather than a historical staple of the house. Across Europe more broadly, craps has always remained something of a niche offering: roulette and baccarat continued to rule the tables, and craps is famously expensive and labor-intensive to run, requiring a large, highly trained crew per table. That operational cost is a big reason the dice game never displaced the wheel in European casinos the way it conquered Las Vegas.

The takeaway for the history of craps is a contrast rather than a connection: two parallel gambling worlds. Monte Carlo represents the aristocratic, European, roulette-and-baccarat tradition that flowered in the 1860s; craps represents the American, populist, dice-rolling tradition that grew from New Orleans streets to Vegas casino floors. Both are central to gambling history — but they are largely separate stories that only converged much later, when global casinos began offering the full international menu of games under one roof.

How did craps become a casino icon?

Craps spread across America through the streets and the military in the early 20th century, then exploded into mainstream casino culture in mid-century Las Vegas. Its journey from sidewalk to casino floor is a story of two very different worlds.

In the early 1900s, "street craps" became enormously popular, especially in African-American communities, played informally with two dice against a wall or curb, with no formal table. This grassroots version kept the game alive and woven into American popular culture.

Then came the wars. Craps was a favorite of American soldiers during World War II, who played it in barracks, on ships, and wherever a flat surface and two dice could be found. The military spread the game across the country and the world, carrying it well beyond its working-class and regional origins.

After the war, the rise of Las Vegas turned craps into a glamorous centerpiece. Through the 1950s and 1960s, casinos in Las Vegas and the Caribbean added more and more craps tables, drawn by the game's energy and the crowds it attracted. The communal, cheering-around-the-table atmosphere — everyone betting on the same roll — made craps one of the most exciting and recognizable games on any casino floor, a status it still holds today.
