One option at roulette is to play black or red positions. The odds are 47.4 percent for red or black, with 5.3 percent going to green for the 0 and 00 on the American wheel. The odds are improved on the European wheel with only one zero. The odds go up to 48.7 percent for red and black, and only 2.6 percent for the green play. The house pays even money on the red and black wins. That is a loss for the player since he or she shouldn't get an extra 2.6 cents on each dollar played. Don't forget the house has to pay salaries, lighting and all the overhead costs. This is one of the ways they do it.
