The Basics of Roulette

Roulette is a casino game in which a small ball rolls around a numbered wheel and people bet on which number it will land on. The game has been popular since its origins in the 17th century. Various fanciful stories surround its creation; one is that it was invented by the 17th-century French mathematician Blaise Pascal during his search for a perpetual motion machine. In fact, the modern game was derived in France from older games such as hoca and portique, and achieved its present wheel and table layout about 1790.

The modern roulette wheel has 37 divisions, alternately colored red and black with a single green zero (on American tables there is an extra green zero). The numbering of the wheel is designed so that, if the ball settles in a number, a player wins. However, the odds of winning depend on what type of bet is placed: bets on individual numbers are called “Inside bets”; those on groups of numbers forming squares or rectangles on the betting mat are called “Outside bets.”

A player places his or her chips on a roulette mat before the croupier spins the wheel. Once the wheel stops spinning, the croupier removes the losing chips from the table and pays out the winning bets according to the payout table. The croupier then repositions the betting mat and the game begins again.

In addition to the symmetry of the numbers on the wheel, there are several other symmetries that can be used in bets. For example, all the low red numbers are on one side of the wheel, while the high black numbers are on the other. The number 29 is also a special case: it’s on the right edge of the wheel, and so has the best chance of landing in a red pocket.

While the rules of roulette are relatively simple, there is a surprising amount of depth to the game for serious players. Whether you’re new to the game or a seasoned gambler, you can learn some basic strategies that will improve your chances of winning.

Besides the basics of strategy, it’s important to set your bankroll before hitting the roulette table. Each table carries a placard that describes the minimum and maximum bets allowed. Choose a table within your budget, and stick to it. If you’re a beginner, it may be best to start with “outside” bets, which are more likely to win than bets on individual numbers. Then, once you’ve gotten the hang of it, you can move on to more complex bets. And remember to have fun!
