Each of the six parts of the American Roulette Wheel are numbered with the letter “A” corresponding to the top portion of the wheel and “E” for the middle portion. The number of letters next to the letter “T” on the wheel will designate the part’s type.
On the left side of the roulette wheel, on the right hand side are sections with the letters “C”D”. These letters correspond to the top and bottom portions of the wheel, respectively. On either side of these letters will be the letters “L”R”.
For those that are not aware, these letters represent the standard of the table and are in-house gurus to some casino companies. If the numbering is changed, it will mean that something is incorrect in the system. Just keep in mind, however, that most “standard” casino tables actually don’t even follow these. They use their own in-house version of the numbering.
There are two “pros” and two “cons” to having a section. The first one is that there is an ease of seeing what is on the table. Because you are seated and don’t have to look at the wheel or view the numbers, you can easily catch a break that would not be possible otherwise. This, of course, can be considered luck, but it is also the casino’s way of keeping the players from seeing all of the numbers.
The other two to sections is that the casino does not have to cut down a portion of the table to fit it into the wheel. It’s much more streamlined and easier to show off if possible.
You should, however, remember that while a wheel does need to be centered perfectly so that it can spin, it cannot be too large. Remember, it’s not the amount of information that you can see, but how you’re able to view it that counts. So, whether the casino uses quarters, dimes, or even larger numbers, the wheel still needs to be perfectly centered.
Because the number of numbers used to print on the roulette wheel is variable, a wheel with smaller numbers can actually help. When the number of numbers printed is large, however, it creates a bad appearance. The action on the wheel is not as lively as when the numbers are small, thus creating a bad impression on the player. Because of this, it is not necessary to know how many numbers to print or how many to place on the wheel.
The bottom line is that while a casino might use sections for variety, if the numbers on the wheel are too large, they may be viewed as a bad influence on the player. Therefore, the number of sections should be adjusted for a nice balance of size, visibility, and contrast, just like any other part of the casino.
