Roulette is not a game of skill, but more a game of chance. Some casinos also offer the European style roulette, which has a single 0 along with the standard 36 numbers. There are also two green slots numbered 0 and 00. In Las Vegas, roulette slots are numbered from 1 to 36 alternating between red and black. A white ball is spun around the wheel as the wheel rotates, and when the ball loses speed, it drops, falling into one of the numbered slots. The Roulette is a spinning wheel that contains slots numbered 1 to 36, as well as two additional slots, 0 and 00. The game of Roulette is a popular, entry-level game that is ideal for novice gamblers because it requires absolutely no skill.
