Roullete is a casino game in which a ball is dropped on a revolving wheel with numbered holes, and the players place bets on which hole the ball will land in. The game is a popular choice for both professional and amateur gamblers, and has many variations.

Roulette was invented in France around the 17th century, and its popularity grew rapidly in illegal gambling dens throughout Europe. In 1843, siblings Louis and Francois Blanc introduced a single zero pocket to the wheel, reducing the house edge significantly, further increasing its appeal. The game reached New Orleans in the US and has since spread worldwide.

There are a number of different roulette versions available online and at physical casinos. The most popular is European roulette, which has a low house edge of only 2.7%. For this reason, we advise all novice players to play this version. If you’re unsure, ask your casino operator which version to play and why.

The table itself is marked off in a series of sections allowing various bets to be placed. These include a single number, various groupings of numbers (such as odd or even), color red or black, and whether the number is high (19-36) or low (1-18). A special revolving disc known as a “wheel” is located in the center of the table. The wheels are made of solid wood slightly convex in shape and are painted either red or black, with a rim containing 37 compartments numbered nonconsecutively from 1 to 36, along with two green compartments on American-style wheels that carry the symbols 0 and 00.
