The Roulette consists of a circular box of form and concave, in whose inner bottom and around a central pivot, it turns a metallic disc that, in its periphery, takes to engravings the numbers. In the inferior immediate part and after them, is the “square” or hollow, where the ball lodges that indicates to the winning number. In center of the revolving disc, a small tower finished off in a cross rises that serves simultaneously as impelling intermediary element.

Two types of Roulettes exist, the American and the European; there are two differences between these, one is that in the American Roulette two favorable numbers to the house exist (Casino) which are the 0 (zero) and the 00 (double zero) and in European the single one exist in 0 (zero); the other difference is that in the American a bet to five numbers can be made which are 0-00-1-2-3 with a single card, this play denominates “special line”, his contraparte in the European Roulette is the play 0-1-2-3 that is equivalent to a normal picture and also is well-known like “special line”; all the others are equal among them. For this description the European Roulette was used.

The convex conformation of the central disc and the inclination downwards and towards the center of the squares destined to lodge to the ball, are predicted so that this one falls unfailingly in some of them, without possibility that it happens of another way.
The Roulette has metallic tops of rhomboid form called chances, ready around the internal part of the box of the Roulette, against which its course hits the ball constantly throughout turning aside itself that he himself in unforseeable form.
The numbered disc of the Roulette contains the numbers of the 1 until the 36 including the zero. These numbers are not ordered corelatively, but in a disposition intentionally disordered and arbitrary.

Observing the Roulette, it can notice that starting off of the “zero” and following the numbers in the sense in that they turn the needles of the clock, the succession of the numbers is the following one:

0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26.

That is to say, that has looked for a alternancia that annuls to proximity of units or tens; and in the case of the tens the greater proximity is of four units, that is number 22 and the 18.

Another particularitity of the numeration is that it groups certain numbers by means of two basic colors: red black and.

The following numbers are red:

1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36.

And black the following ones:

2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35.

This disposition does not group prime numbers, nor to pairs or odd numbers. The reason of this distribution can be connecting the ascending order from zero.

With it one is able to almost move in diametrical form the corelative numbers, and the colors that correspond to them happen alternadamente.

All classic Roulette contains, in addition, a cloth (rug) in which are printings the thirty and six numbers headed by the zero, divided in three columns and as well in three dozens. Surrounding them in rectangle form there are subdivisions that indicate “pairs”, “odd numbers”, “color”, “columns”, etc., in where the bets by means of cards of value or the table are placed.

The cards with which one gambles in a Roulette in individual, that is, the cards of that Roulette; they are of colors so that they are different from the others from the same table and has a number or a figure that makes different from those of other tables of Roulette.

All the cards of Roulette, including those of value that are noticeable with numbers that indicate their value in currencies are done of plastic.
