First of all, the wheel is positioned at the centre of the table with betting grids located on both sides. The table layout is where the real difference lies. No matter which roulette variant is more to your liking, you should remember that roulette wheels are designed in such a way so as to ensure that high, low, odd, even, red, and black numbers will be evenly distributed. The few numbers located in close proximity to the green zero pocket are the only exceptions to this rule. Additionally, each pair of even numbers is followed by a pair of odd numbers. However, it does not take long for one to notice that the red and black numbers on the wheel alternate. In fact, the pattern they follow is seemingly random and differs from that on the American roulette wheel. The numbers on the wheel are not displayed in a consecutive order. The remaining pockets are coloured in red and black and contain numbers 1 through 36. One of the pockets is coloured in green and contains the zero. The French variation of the game is played on a standard European wheel which has a total of 37 pockets.
