When was roulette created?

When it comes to the origins of roulette, experts agree that it was invented in the 17th century, specifically in 1645, by the French mathematician Blaise Pascal. According to legend, roulette was born from an attempt to design a perpetual motion machine. Whether this is true or not remains unknown.

If we consider roulette as a wheel with a zero, such a version emerged in the mid-18th century, credited to brothers Francois and Louis Blanc. They introduced the concept of the house edge, which refers to the advantage the casino holds over players in the long term.
