The cloth covered betting area on a roulette table is known as the “layout”. The layout is either single zero or double zero. The European style layout has a single zero, and the American style layout is usually a double zero. The American style roulette table with a wheel at one end is now used in most casinos. The French style table with a wheel in the centre and a layout on either side is rarely found outside of Monte Carlo.
