The game of roulette is usually played with an elongated table. At one end of the table is the roulette wheel, with a notch in the table where the dealer stands. The table has a felt layout on it with boxes for the numbers 1 through 36 arranged in three columns of twelve rows. At the end of the section of the layout closest to the dealer, above 1, 2, and 3, are boxes for 0 and 00. Each of the numbers from 1 to 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. However, at the other end of the rectangle away from the dealer are boxes for bets on each of the three columns.
The roulette wheel has 38 numbered slots, each with the same colored background as the corresponding number on the table layout. The small, hard ball used to be made with ivory; now it’s usually made of plastic. The dealer spins the wheel in one direction, then spins the ball in the opposite direction around a track on the bowl-shaped recess that holds the wheel. When the speed of the ball slows down, it falls off the track toward the wheel itself, and bounces around until it settles in a numbered slot.
Roulette is solely a game of chance, and no way of betting, money management, or careful observation will let you win all the time. Many have tried it, and many have failed. You must not forget that the roulette wheel is 100% random.
