Roulette is a game with many different bet types. These bets have different odds and payouts. It is best to set a budget before playing roulette.
European roulette is the most popular variation at both physical and online casinos. It has a single zero pocket that reduces the house edge to a low figure.
There are a few theories about the origin of roulette. One popular theory is that it was invented by 17th century French math wizard Blaise Pascal, as part of his quest to create a perpetual motion machine. Another theory is that it was derived from the ancient Chinese game of Hoca and Portique, which involved betting on the outcome of a spinning wheel. Some people also believe that it was brought to Europe by Dominican Monks.
However, it is hard to verify these claims. There is not much evidence that proves these theories, and they are largely just speculations. There is no doubt that roulette was popular amongst Roman soldiers, though, who played a game similar to modern-day roulette. This game involved placing shields with symbols on them, which would be spun.
