The Basics of Roulette


Roulette is a casino game in which the ball rolls around a wheel and people bet on what number it will land on. Players place bets by placing chips on a betting table. Bets on a single number are called “inside bets.” Bets on groups of numbers are called “outside bets.” Some outside bets pay 2-1 while others pay even money. The game of roulette originated in Europe and is played in most casinos and gambling dens.

The roulette wheel consists of a spinning disk with divisions numbered from 1 to 36 and alternately red and black and a single green zero (on American tables there is also an extra green division numbered 0). The ball, which is rolled around the edge of the disc, comes to rest in one of the numbered compartments. When a number is selected, the dealer places a marker on that space on the betting table. The losing bets are cleared off the table, and the winning bettors get paid.

The game has long been a favorite of gamblers and is considered to be a game of pure chance. Despite this, some people claim that there is skill involved in selecting which numbers to bet on and some have even developed systems for winning at the game. However, any player, regardless of which roulette strategy they choose to use, must face the fact that there is no way to beat the house edge of 2.70%.

Each roulette table carries a placard that lists the minimum and maximum bets for that particular table. Typically, the minimum bet is $5 and the maximum is $1,000 for outside bets and $500 for inside bets. Before you begin playing, set a budget for your bets and stick to it. If you win, cash out your winnings quickly and keep betting within your predetermined limit.

Roulette, a game in which a small ball is spun around on a wheel and bets are placed on what number it will land on, was first introduced in a primitive form in the 17th century by French physicist Blaise Pascal as part of his attempt to design a perpetual motion machine. He based his version on older games such as hoca and portique. The modern roulette wheel and betting table evolved in the 18th century.

Players make bets by laying down chips on the betting mat, which shows the specific location where each type of bet will be made. Unlike the traditional ivory balls used in European casinos, today’s professional roulette balls are often made of resin or Teflon. These balls have a smaller diameter and weigh less, which makes them spin more unpredictably on the wheel track and jump more unpredictably before they land on a number than a bigger, heavier ivory ball would. However, the difference is not significant enough to significantly affect the outcome of a spin.
