Roulette is normally played with an elongated table. At one end of the table is a wheel, with a notch in the table for the dealer to stand at. The surface of the table has a felt layout on it with boxes numbered from 1 to 36 arranged in three columns of twelve. At the end of the part of the layout that is nearest to the dealer, above 1, 2, and 3, are boxes for 0 and 00. Each of the numbers 1 through 36 is surrounded by either a red or black oval or rectangle. The 0 and 00 have green backgrounds. This rectangular grid, with a box for each number, is used for wagers called “inside bets.”
Outside the numbered boxes are several other boxes for “outside bets,” encompassing up to 18 numbers at a time. Most of the areas for outside bets are on the long side of the table across from the dealer. Also, at the end of the rectangle away from the dealer are boxes for bets on each of the 3 columns.
The wheel itself has 38 numbered slots, each slot with the same colored background as the corresponding number on the table layout. The small, hard ball used to be made from ivory; now it is most of the time made of plastic. The dealer spins the wheel in one direction, and spins the ball in the other direction around a track on the bowl-shaped recess that holds the wheel. When the speed of the ball slows down, it falls from the track toward the wheel itself, and bounces around until it falls in a numbered slot.
Roulette is purely a game of chance, and no method of betting, money management, or careful observation can let you win every single time. Everyone who have tried it failed. You must not forget that the roulette wheel is completely random.
