Roulette betting takes place with specialized chips. Each player gets a color and each bet is placed on the area of the table map that corresponds to its denomination.
Do not be fooled by any betting systems that claim to beat the odds. They are not true and can lead to huge losses.
Origins
While most gamblers associate the game of roulette with Las Vegas, there is a much longer history to this popular pastime. The exact origins are a bit fuzzy, but most historians believe that the game was first invented in 1655 by Blaise Pascal. The famous French mathematician was working on his quest to create a perpetual motion machine when he stumbled upon the idea for roulette.
Some people claim that the game evolved from older games like portique, hoca, bassette, and even-odd. Other historians point to an alleged ancestor in Italy called Biribi. The Blanc brothers later added a single-zero variant of the game to make it more profitable, and this became the standard version used today in Europe. In America, the double-zero wheel was retained.
