The game of roulette is one of the most popular casino games. It consists of a rotating wheel with colored pockets, which are numbered from 1 to 36 in alternating red and black colors. There is also a green division numbered 0. The ball is spun around the outer edge of the spinning wheel and comes to rest in one of the pockets. The game of roulette was invented by the 17th-century French mathematician Blaise Pascal and has been widely adopted for use in casinos and gambling dens.
There are several different types of bets in the game of roulette. The most basic bet is a straight bet, where the player selects a single number on the board. There is also a split bet, where the player places two adjacent numbers on the board, and a corner (square) bet, where players place chips on the corners of four adjacent numbers. Finally, there is a street bet, where the player places chips on three consecutive numbers in a row on the board.
Outside bets are wagers on groups of numbers and offer lower payouts if won. These bets are good for newcomers to the game as they cover more of the table and are less risky than individual numbers. They include the dozens bet, where the player wagers that the winning number will belong to the first, second or third dozens on the layout. The odds for this bet are 2-1. There is also the odd or even bet, where the player wagers that it will be either an odd or an even number. This bet pays out 1-1.
Inside bets, on the other hand, are bets on individual numbers and offer higher payouts if won. These bets include the straight bet, which requires the player to place chips in the center of a square. There is also the double-zero bet, where the player places chips in the box containing the zero and the rows featuring 1, 2 and 3. This bet has a house edge of 6.37 percent.
The best way to win at roulette is by following a strategy that takes advantage of the game’s house edge. While the range of the house edge is not as high as that of craps, it is still significant enough to make a difference in your bankroll. The key is to choose the right betting system and stick with it until you’ve won a few times.
In addition to the house edge, you should also consider your playing style and budget before choosing a roulette strategy. The best option is to play European roulette, as it offers a much lower house edge than the American version.

Roulette is a game that’s easy to learn but difficult to master. It’s important to understand the rules before you start playing, so you can make smart decisions about how much to bet and when.
