From Hazard to Craps: How England's Dice Game Became America's

Craps grew from Hazard, an English dice game carried through French-speaking play into Louisiana, then simplified in America around a fixed main of 7. Its name probably comes from “crabs”, an old losing throw, but the record is patchy.

The history of craps is not a clean line from one inventor to one rulebook. It is a working gambler’s history: sailors, soldiers, planters, street players and casino operators keeping the parts that were quick, memorable and easy to bet on. The shape is clear. The paperwork is not.

That matters because a lot of popular craps origin stories are tidy after the fact. Bernard de Marigny, New Orleans, French crapaud, English Hazard, crooked dice, John H. Winn: all appear in the usual telling. Some pieces are well supported. Some are the usual story, unverified. The honest version is more interesting than the polished one.

How did Hazard become craps in America?

Hazard became craps by losing some of its choices and gaining a table built for public betting. In Hazard, the caster could choose a “main”, usually from 5 to 9, and the rest of the throw depended on that number. In American craps, the main effectively settled at 7. That one change made the game easier to teach, easier to watch and easier to price.

The old English game was known by the late medieval period. Chaucer’s Canterbury Tales, written in the late 14th century, uses Hazard as a word for dice gambling. By the 18th century, English gaming books were describing rules recognisably related to the Hazard dice game later associated with craps origin stories.

How it crossed the Atlantic is less tidy. French-speaking players carried versions of Hazard into North America, and Louisiana is the place where the American game is most strongly associated. The usual story, unverified in its neatest form, says Bernard Xavier Philippe de Marigny de Mandeville brought a simplified version from England to New Orleans in the early 19th century and helped make it fashionable.

By the 19th century, craps was a street and saloon game as much as a parlour one. Players did not need cards, a board or a banker. Two dice and someone willing to cover the shooter’s bet were enough. The casino table came later, with written layouts, fixed payouts, crews to run the game and rules designed to make every bet visible.

What was Hazard before it crossed the Atlantic?

Hazard was a two-dice gambling game, but calling it early craps in older clothes flattens the difference. Its key feature was the “main”. The caster chose a main, commonly 5, 6, 7, 8 or 9, then rolled. Depending on that main, some totals won at once, some lost at once, and some became the caster’s “chance”. If a chance was set, the caster tried to roll that chance again before rolling the main.

That makes Hazard slower to explain than craps. It also gives the caster a choice that modern pass-line craps removes. Printed rules vary, which is normal for gambling games that lived in inns and private rooms before they were pinned down by casinos.

• Equipment: two dice, a surface to throw on, and money or counters for stakes.
• Player role: the caster threw the dice; other players backed or opposed the throw.
• Main: a chosen target number, usually between 5 and 9, that controlled the result table.
• Chance: a point-like number made after the first throw, which the caster then had to repeat before the main appeared.
• Modern echo: with a main of 7, the pattern starts to resemble today’s come-out roll: 7 or 11 wins, 2, 3 or 12 loses, and the other totals become points.

The important shift was not a new pair of dice. It was the removal of a moving rule.

Where does the word “craps” come from?

• The strongest trail runs through “crabs”. In Hazard, “crabs” referred to losing throws. The word fits the game’s mechanics and gives a plausible route to “craps” in American speech.
• The French “crapaud” story is famous but thin. Crapaud means toad. Popular accounts say French players crouched over street dice like toads, and the word became craps. It is a good image. The usual story, unverified, is not the same as evidence.
• Hazard itself has disputed roots. One common explanation connects it to Arabic al-zahr, often glossed as dice. Another old tale links it to a castle named Hasart during the Crusades. The castle version is folklore unless better evidence appears.
• Spelling followed speech. Gambling words often changed in mouths before they settled in print. A move from crabs to craps is phonetically small, especially in a fast street game.
• The safe answer is modest. The craps origin most consistent with the rules is that “craps” comes from the old losing “crabs” throw in Hazard, with French and American usage shaping the final form.

How did street craps change the game people know now?

1. It stripped the game to a shooter and a bet. Street craps did not need the full casino layout. One player shot, another player or group “faded” the bet, meaning they covered the money. This made the game portable. A pavement, an alley, a barracks floor or a back room was enough.
2. It made the pass-line rhythm dominant. The easy story of the game became: win now on 7 or 11, lose now on 2, 3 or 12, otherwise make the point before 7. That structure is quicker to understand than Hazard’s changing main.
3. It encouraged side action. People could bet with or against the shooter, make private wagers, or call out propositions. Street craps history is full of informal betting because there was no house layout saying which bets existed and which did not.
4. It exposed a trust problem. With no casino crew, no boxman and no controlled dice procedure, players had to trust the shooter, the dice and the person holding the stakes. Disputes were part of the risk. Casinos solved that problem by making bets public and procedure-heavy.
5. It fed the casino table rather than replacing it. Modern craps kept the shooter, the come-out roll and the point, then added a banked game, fixed payouts, written bet areas and free odds. John H. Winn is commonly credited with important early 20th-century changes to the casino version, including the don’t-side structure used to balance action.

What parts of the old dice game still survive at the table?

The modern table looks far removed from Hazard, but the bones are visible. The surviving parts are the ones that help a player decide what the next roll means.

The table adds many bets Hazard did not require, but it did not invent the central tension. It priced it.

Frequently asked questions

Final thoughts

If a friend asked what to take from all this, I would point at the first roll. The game’s history is sitting there in plain sight. A single throw can win, lose or create a number that must be repeated before disaster arrives. That is old gambling design: quick judgement, public suspense, no ornament needed.

The rest is culture and control. Hazard belonged to a world where rules could vary by room. Street craps belonged to players who needed speed and portability more than paperwork. Casino craps belongs to a house that must settle every chip cleanly, pay every bet by rule and keep the dice in view. None of those stages is purer than the others. Each one answers a different problem.

The name is the same sort of thing. “Crabs” becoming “craps” is believable because it fits both sound and play. The crapaud tale survives because it is memorable. History often has both: the likely answer and the better anecdote. The useful habit is to enjoy the anecdote without handing it the keys.
