Roulette rules

Roulette is a casino game named after the French word meaning little wheel. It is based on a rotating device which consists of two centered wheels. The bigger wheel is still, the smaller one rotates and is divided into 37 (in French Roulette) or into 38 coloured and numbered pockets (in American Roulette).


To determine the winning number and color, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the circumference of the wheel. The ball eventually loses momentum and falls onto the wheel and into one of 37 or 38 colored and numbered pockets on the wheel.

Blaise Pascal, a mathematician and physician, came up with the idea of roulette in 17th century. At that me, he was fascinated and obsessed with the thought of contructing a so-called perpetuum mobile. Roulette was first played in year 1796 in Paris. In year 1842, the Frenchmen François and Louis Blanc added the 37th part - the zero - which moved the probability of winning to the operator's benefit, and in the USA at the beginning of the 19th century, it went even further, when the 38th part was added, and it was marked with the '00' symbol.

The division of the wheel

In French roulette, the wheel is divided into 37 parts, from which 36 are numbered from 1 to 36, but those numbers are not lined up in order. Half of the numbers are red and the other half are black. The only exception is the zero which is green (in French roulette). In American roulette, there is an extra 38th part, which is the double zero.

It's advantagous to wait until the same colour is hit many times in a row and only then to start betting. Therefore, let the roulette rotate a bit without risking a single token! Wait for the right numbers to come and then start playing.

Always follow there 7 rules for playing:

  • Discipline. It is necessary to determine limits for winning and losing, and when you reach those limits, end the game. If you don't stick to this rule, the mathematical advantage of the casino will get you.
  • Choosing the roulette. Rather play on a European or French roulette. The American one has two zeroes, which gives more chances to the casino.
  • Money. Always have enough money in the bank, which will enable you to overcome a long unsuccessful sequence. If your basic bet is one token, then the minimum bank is 200 tokens.
  • Losing. If you lose, it's no good to try to win the money back in an instant. Go back to the game next day.
  • Roulette systems. Are you playing a system that you believe in? Great, then stick to it.
  • Greed. If one is winning, they never have enough. In roulette, however, you can really mess up by doing this. Therefore, decide on a real limit for winning or losing, see the first rule.
  • Choosing the right casino. Choose your online casino with caution. Small, new or unknown casinos can have cheat systems in which you can't ever win, or they can avoid the payment of the winnings.
