It contained the same elements as the modern wheels do - the black and red sectors, the position of the sectors from 1 to 36 around the wheel and the 00 sector in the American roulette (the odds of a game with a 00 sector are more favorable to the casinos since the chance for the players to lose is bigger). In the next 50–60 years the roulette had gone through many modifications and transformations until 1796 when in Paris the game started to be played in its present form and the modern roulette wheels became popular in the casinos in Paris. In 1739, Roly-Poly was prohibited in United Kingdom as well as many other games of chance which were popular at that time. The game is considered to be a combination of the English wheel games Reiner, Ace of Hearts, Roly-Poly, an Italian board game named Hoca and Biribi and an already existing French board game of the same name - Roulette.

In 1843, in the German spa casino town of Bad Homburg, fellow Frenchmen François and Louis Blanc introduced the single 0 style roulette wheel in order to compete against other casinos offering the traditional wheel with single and double zero house pockets. To avoid confusion, the color green was selected for the zeros in roulette wheels starting in the 1800s. The roulette wheels used in the casinos of Paris in the late 1790s had red for the single zero and black for the double zero. An even earlier reference to a game of this name was published in regulations for New France (Québec) in 1758, which banned the games of “dice, hoca, faro, and roulette”.

The description included the house pockets, “There are exactly two slots reserved for the bank, whence it derives its sole mathematical advantage.” It then goes on to describe the layout with, “…two betting spaces containing the bank’s two numbers, zero and double zero”. An early description of the roulette game in its current form is found in a French novel La Roulette, ou le Jour by Jaques Lablee, which describes a roulette wheel in the Palais Royal in Paris in 1796.

The game has been played in its present form since as early as 1796 in Paris. The roulette mechanism is a hybrid of a gaming wheel invented in 1720 and the Italian game Biribi.

Many historians believe Blaise Pascal introduced a primitive form of roulette in the 17th century in his search for a perpetual motion machine. The first form of roulette was devised in 18th century France. It is considered that Blaise Pascal (the famous French mathematician and scientist) invented the roulette mechanism in 1657, in his search for a perpetual motion machine. Its history takes us back to the times when the first forms of roulette have appeared in Europe during the 17th and 18th century. The game has been entertaining gamblers from all over the world for nearly 300 years.
