Roulette is one of the most iconic casino games in the world and can be found on the floors of most bricks and mortar establishments. It’s also widely played online with numerous variants offered by virtual casinos.

Basic Rules of Roulette

Roulette is played with a large wheel that comprises either 37 (European) or 38 (American) pockets. Both variants feature 36 numbered stops although the American version also contains an extra 00 pocket. Each of the 36 stops are evenly coloured either red or black while the pockets are green.

A dealer or croupier spins a ball on the outer rim of the wheel which eventually falls into a numbered stop. Prior to each spin, the player predicts the number on which the ball will land.
Bets are made on a table which represents each number through a grid layout. Players can place bets on single numbers and/or combinations as well as number colours, rows and columns.

Once the ball has landed in a stop, the croupier will place a marker/dolly on the corresponding table number. Any bets on that number are then paid out.

History of Roulette

The game is thought to have originated in 17th century France with mathematician Blaise Pascal. However, the actual roulette mechanism derives from an earlier Italian game called Biribi.

Modern roulette has been played since at least 1796. We know this because of a novel penned that year by Jaques Lablee, entitled La Roulette, Ou Le Jour. In it the author describes in some detail, a roulette wheel used in the Palais Royal.

During this period, French incarnations of roulette featured a red single zero and black double zero. Both of these were considered house pockets so any bets placed on red or black were lost should the ball land in either. To prevent confusion, green colours were eventually used from the 1800s onwards.

In 1843, French brothers Francois and Louis Blanc introduced a single zero roulette wheel in order to compete with the double zero house pockets used by most casinos of the time. Both versions of the game became wildly popular across Europe during the 19th.

But it was the single zero game which eventually gained supremacy after Prince Charles of Monaco III requested it be adopted by his tiny principality in the late 19th century. And it was here that modern French roulette became firmly established in Europe as the most fashionable casino game of its era.

It was during this period, that the double-zero variant was introduced to the United States. Starting on the Mississippi, the game quickly spread westward as more and more gambling dens adopted the well-established European game.
