Roullete is a game of chance played at a table with a spinning wheel having numbered compartments that afford a number of betting options. A small ball is spun around the wheel and allowed to come to rest in one of the compartments. If the bet was made on that number, its color (red or black), odd or even, or a specific grouping of numbers, then the player wins.

The earliest records of this game date back to the 17th century when it was first invented in a primitive form by Blaise Pascal, the French mathematician, philosopher and inventor. In his attempts to create a perpetual motion machine, he designed a cylinder with thirty-six compartments numbered 1 through 36 in a non-consecutive pattern and also a green compartment labelled 0 (in the European version) and a second green division marked 00 (on American roulette wheels).

There are many different systems of playing and supposedly winning at roulette. These range from incredibly simple to amazingly complex. However, they all boil down to the same thing – beat the house edge by avoiding bets that pay out less than their true odds of winning.

When playing roulette, it’s important to set a budget before entering the casino and sticking to it. Each roulette table carries a placard explaining the minimum and maximum bets allowed. Choose a table within your budget and make sure to cash out winning bets as soon as possible. Using your winnings to place future bets will only lower the overall return on your wager.

One way casinos could prevent prediction is to simply call “no more bets” before the ball is rolled, but they won’t do that because it would cut into profits and deter casual players. Instead, they continue to try to improve the quality of the roulette wheel and table layouts, while trying to compensate for the inherent prediction flaws with new technology.

A major change has been the use of a lighter, synthetic ivory-look ball that’s actually made from resin or Teflon. The smaller ball makes more revolutions on the wheel track and jumps more unpredictably before landing on a number, making it harder to predict its location. However, this is not enough to overcome the house edge.
