Three major roulette variants are played in casinos around the world: French Roulette, American Roulette and so-called Anglo-American (European) Roulette. These variations may differ by the following characters:
- By the number of numbers on the wheel, ie the existence or non-existence of the thirty-eight number denoted as double zero (00) and their arrangement
- Placing and marking out bets on the game table canvas
- The type of game chips used
- Settling equal bets in case of zero as winning number
- The total number of betting options on the table.
French roulette differs from American and European roulette mainly by the size of the table and the playing area of the canvas. The printed area of the screen section of the screen is about 2.5 times larger than the US type. Another significant difference is that somewhat larger squares (than American roulette) for straight bets are placed on both sides of the numerical grid for French roulette, while for the American type only along one side. The French tables also sometimes (as opposed to the American ones) are doubled – they have a drawing of a zero-end board facing each other on opposite sides of the wheel (played either on either side or only on one side depending on how many players are ready to play) Unlike American roulette, the French table only plays value tokens, so all players have the same chips, which can only differ in value. The inscriptions are made in French on the French roulette wheel, so the capital letters D, M and P in the dozens bets are the initials of the words Dernier, Milieu (or Moyenne) and Prime, or Last, Middle and First. These boxes are placed side by side on the screen and symmetrically on both sides of the bottom end of the numeric network.
American roulette differs fundamentally from the other two in particular by the number of numbers (it also has a double zero, so the total number of numbers on the round is 38) and their arrangement. While the numbers keep their color, they alternate regularly (large – small – large, etc.), but the order in which they follow one another is absolutely different. At first glance, it might seem that even here their deployment is completely random. On closer inspection, however, we can see that there is this system in the disposition of numbers on the American bicycle: odd numbers are always one unit larger, even but opposite, by one unit. As with the French game, the sequence of numbers for all American roulette games is identical.
On some American wheels, however, the opposing numbers may be zero and the double zero may be exchanged – but usually, a single zero lies between the twenty-eight and the two. The canvas is smaller in the American game than in the French and differs in the layout of the betting options. The basic difference is that the bets for external bets (ie, straight bets and column and dozen bets) are located only on one (usually left) side of the numeric network. American roulette is also different from the French game, not least the type of playing chips used. They are completely different in shape and material and are still divided into two types. So-called. Wheel checks are always used on a selected roulette table and are used to better identify bet owners. Cash chips or value chips are played at all casino tables.
