Roulette is a casino game that originated in Europe and has since become one of the most popular games in casinos. It is also considered one of the most difficult games to master, so you should prepare well before playing it.

Roulette bets are divided into inside bets and outside bets. Inside bets are those placed on single numbers or various groupings of numbers. The payouts for these bets are based on their probability.

The game of roulette is played on a wheel that consists of a small, convex wooden disk painted red and black. The wheel is surrounded by metal partitions known as separators or frets. Its inner ring is divided into 36 compartments, each marked nonconsecutively with the number 1 to 36, and a 37th pocket on European-style wheels painted green to indicate the zero.

Players place their bets on the individual pockets or groupings of pockets, depending on their position. There are a variety of combinations that can be made, including odd or even, red or black, high (19-36) or low (1-18).

Announced Bets

These special betting combinations are most commonly found in French Roulette, but they are sometimes present in European Roulette variations as well. They are all part of the rules of the game and you need to know them by heart to play it properly.

For instance, the Voisins du Zero covers 12 numbers on the wheel – from 27 to 33 – and it is located opposite on the table compared to the Voisins du Lot. It is very important to understand these bets, together with the roulette rules, if you want to play them properly and win some money.

The house edge in roulette ranges from 2.63 percent to 7.89 percent, depending on the type of wheel used and whether it is an American or European version. However, it is very rare to find a game with a significantly higher house edge than the standard European variant.
