Roulette is a casino game that involves a spinning wheel and a table with various types of bets. A player may place bets on a single number, various groups of numbers, the color red or black, and whether the number is odd or even. A croupier then throws a ball into the wheel and the winners are paid according to their bets. The odds of winning differ depending on the type of bet, but on average a bet on the Dozens pays 2-1.
The wheel consists of a solid wooden disk, slightly convex in shape with thirty-six compartments painted alternately red and black. On European wheels a 37th compartment, painted green, carries the number 0, and on American wheels two additional green compartments carry the numbers 0 and 00. The wheel is balanced and spins smoothly on a metal spindle.
Fanciful stories abound of how the game was invented. Among the most popular is that it was invented by 17th-century French mathematician Blaise Pascal as part of his work on perpetual motion machines. It was then modified by Dominican monks and brought to Europe where it became very popular.
It is still a mainstay of casino games worldwide and has the highest following among American table games, although it does not draw the crowds of blackjack or craps. Nevertheless, it is not a game for the faint of heart and requires skill and concentration.
If you walk into any casino that offers table games, you will most likely find a roulette table. The game is fun and fast-paced, offering many betting options. It is easy enough for a beginner to enjoy, but it is also challenging and interesting for experienced players. While casinos can’t stop prediction, they can limit the number of bets placed before the game starts. That would cut into profits and discourage casual gamblers.
