Regardless of whether it is American Roulette or European Roulette, this betting grid is valid for both types of games. As it is known, the numbers of the roulette wheels are divided into two colors, red and black.
Players can place bets by choosing any of these colors. If the player has selected the lucky color, the bet placed by him is doubled. The chances of winning are almost equal. However, in this category of bets, the casino has a small advantage, because the roulette wheel also contains the green color assigned to the zero figure. Therefore, in the long run, the casino has the advantage.
