The making of the little wheel
Roulette took shape in France and travelled through the spa towns and casino resorts of the nineteenth century. Its story has no single proven inventor.

01 / An uncertain beginning
Roulette means “little wheel” in French. The casino game took shape in eighteenth-century France, within a much older culture of games of chance. Neither a single inventor nor an exact invention date is known.
Paris · 1658
In Histoire de la roulette, Pascal used roulette for the cycloid: the path of a point on a rolling circle. This work does not establish him as the inventor of the casino game.
Roll the circle
La trochoïde ou la cycloïdeThe trochoid or cycloid
E.O. — Even and Odd — was played in eighteenth-century Britain. Gamblers gather around a circular table marked with letters, rather than the numbered grid familiar today.
Games such as E.O., hoca and biribi belonged to roulette’s wider gaming culture. Similarities do not establish a single, uninterrupted line of invention.
France · late eighteenth century
Roulette developed in France in the eighteenth century. Jacques Lablée’s novel describes a game already being played in Paris; it is a literary account, not a record of the first spin.
1796Commonly cited narrative setting
1802An early edition of Lablée’s novel
Stories crediting monks, missionaries or Pascal’s supposed search for perpetual motion remain unproven origin legends.
02 / Paris, 1658
Pascal investigated the cycloid’s mathematical properties and challenged other geometers to solve problems about it. His “roulette” was a curve traced by a rolling circle, more than a century before the Paris game described by Lablée.
The word on the page
In Pascal’s title, roulette is also called the trochoid or cycloid. A point on the circle’s rim traces an arch as the circle rolls without slipping. After one complete turn, the point touches the ground again.
03 / Paris, late eighteenth century
The Palais-Royal’s arcades brought together shops, promenaders and places of entertainment. Gambling was part of this public life, and roulette became one of the city’s games.
The commonly cited year in which Lablée’s account of Paris roulette is set.
The date of a surviving edition. The narrative looks back to the previous century.
Jacques Lablée’s novel, La Roulette, ou Histoire d’un joueur, appeared around 1801–1802 and describes a game already being played. Its publication does not mark roulette’s invention.
Pocket colours and number arrangements varied as roulette developed. The green zeros and familiar sequences of today’s wheels should not be assumed for every early table.
04 / Homburg, early 1840s
François and Louis Blanc promoted roulette without the double zero in Homburg, now Bad Homburg. The casino opened in 1841. A surviving wheel is associated with single-zero play there in May of that year.
The casino within the spa resort
The Kurhaus setting placed gambling alongside gardens, concerts and the social life of a spa town. The Blanc casino moved into the Kurhaus in 1843, two years after its opening in Homburg.
Removing 00 left 37 pockets instead of 38. A Red bet still won on 18 numbers and paid 1:1, but now lost on 19 outcomes instead of 20. That reduced the casino’s average advantage.
House edge is the casino’s average share of all money wagered over the long run. These figures use standard even-money payouts, without La Partage or En Prison.
How zero changes the odds05 / Monaco becomes a destination
François Blanc brought his experience in Homburg to Monaco. In Monaco, the gaming enterprise developed alongside hotels, gardens and, later, an ambitious programme of music and theatre.
Casino ventures in Monaco already had authorization in 1856. In 1863, Prince Charles III established Société des Bains de Mer. François Blanc brought experience from Homburg to the enterprise on the Spélugues plateau.
Hotels, gardens and places to gather broadened the attraction beyond the gaming room. François and Marie Blanc helped develop the Hôtel de Paris; the predecessor of the Café de Paris opened in 1868.
On 1 June 1866, Charles III named the district Monte Carlo. The casino, hotels, villas and gardens were becoming a destination in their own right, distinct from the older town of Monaco.
The casino expanded as the resort grew. Rebuilding in 1878 transformed the earlier building, whose seaward façade appears in this photograph.
Marie Blanc commissioned Charles Garnier in 1878. His concert hall was inaugurated on 25 January 1879; the first opera followed on 8 February. Music and theatre became part of the casino resort’s social life.
Salle Garnier added a theatre to the gaming resort. Further extensions and alterations shaped the casino complex over the following decades.
06 / American roulette, nineteenth century
Roulette spread through Europe and North America with variations in rules and equipment. By the late nineteenth century, American manufacturers were making distinctive betting layouts. One surviving cloth links the double-zero game to Providence, Rhode Island.
Providence, Rhode Island · c.1890
The surviving gilt-lettered betting layout was made by William Ellis in Providence, Rhode Island, around 1890. The cloth measures 31 × 53 inches.
By the late nineteenth century, American makers were supplying roulette’s betting surface as well as its wheel.
American equipment was not uniform. Early twentieth-century American roulette equipment used varying number ranges and sometimes an “Eagle Bird” mark alongside zeros. Ellis’s double-zero cloth is one surviving form; a betting layout does not specify the wheel’s pocket order.
Two-zero roulette also existed in Europe. The American label describes a format that became familiar in the United States, not proof that Americans invented the extra zero.
Present-day American roulette07 / Tables, circuits and networks
Electrical circuits could select a result, terminals could connect players to a shared table, and networks could deliver either software games or live video.
A physical result, at the table
Players gathered around the betting layout. The dealer operated the wheel and settled wagers using the number where the ball landed.
1979 filing / 1981 patent
Hoffman’s design uses 38 LEDs, a pulse generator and counters. Lights switch on in sequence; the circuit stops with one light illuminated. It is an electronic roulette design, not a record of the first commercial machine.
The internet era
Networked casino software separated the player’s screen from the system resolving the wager. In RNG roulette, a random number generator supplies the result; the animated wheel presents it.
A computer display alone does not identify the mechanism. A terminal can receive a physical wheel’s result, while an RNG game generates its outcome electronically.
2006 · Evolution company milestone
Evolution was founded in 2006 with a live-dealer offering that included roulette, blackjack and baccarat. This dates the company’s business, not the invention of live roulette.
A camera transmits the physical round while an online interface handles bets and settlement. The ball still determines the roulette result; the broadcast makes the table visible elsewhere.
These forms continued alongside one another. Automation, a software-generated outcome and a live video feed are different changes to how roulette is operated or delivered.

The little wheel, in a larger world
From Parisian gaming rooms to Homburg and Monte Carlo, roulette grew alongside places of leisure. Today, its single- and double-zero formats remain familiar on casino floors and online.
