An online roulette table will surely have all the numbers going from zero to thirty-six. In the case of the online American roulette we will have an additional box with the double zero. In the case of an online European roulette, the double zero will not be present and we will have the thirty-seven numbers going from zero to thirty-six.
All the numbers of the online roulette between the one and the thirty-six will be have a color which may be either black or red. The zero (and eventually the double zero) will be green. This difference which may be formal and exclusively related to design has very deep foundations regarding the bets that can be made on the online roulette table. This has to do in particular with outside bets leaving outside the zero (and eventually the double zero).
