The origin of Roulette is uncertain. Some authors claim that it was invented by Blaise Pascal the mathematician, while others suggest that it was introduced by Dominicans from China. It was in the 18th century that Prince Charles of Monaco promoted the game in order to revive an economy then faltering. Roulette was exported to America early in the same century, making a first appearance in New Orleans. The popularity of the game including double zero earned it the name of “American Roulette” while the simple zero, favorite of Europeans, is associated with French or European Roulette.
Roulette is played with a wheel composed of thirty-six (slots) numbered from 1 to 36, the half of which is black and the other of red, a ball that rotates around the wheel, and a carpet that allows players to place their bet. Added to the 36 numbers is a 0 (zero) for European Roulette, and a 0 (zero) plus a 0 (double zero) for American Roulette.
Once the players have placed their bet on the mat, the game can begin. The Croupier turns the wheel in one direction then launches the ball in the opposite direction. Players can bet until the Croupier exclaims, “Nothing goes!” As soon as the ball stops on a number, the Dealer announces the winning number and places a marker on the mat in front of the same number. The Croupier recovers the losing bets before paying the winners.
The main difference in the popularity of the two games, European and American, comes from the fact that the chances of winning are better at European Roulette. Indeed, since there are 36 digits, and only one of them comes out winner, the possibilities are therefore 35 against 1, the amount paid by the casino to the player who bet on this number. But by adding a zero to European Roulette, the odds become 36 to 1, while they are in the range of 37 to 1 in American Roulette (0 + 00). The zero and double zero represent the avavntage of the casino and the house still pays only 35 X the stake. Unless the zero (or double zero) is bet, all bets become lost if the ball stops on that number.
European Roulette offers the player the “In Prison” rule which allows the player either to recover half of his bet, in the event that the zero wins, or to leave his bet on the table for another round hoping to win. recover it. These advantages explain the popularity of European Roulette to the detriment of the American.
The different bets
Roulette offers the player a multitude of betting options, more than any other table at the casino. There are more than 150 possible combinations and the player can bet as much as he wants while being sure to respect the minimum and maximum bets of the casino. The table is composed of inside and outside stakes.
In Full (single digit)
The stakes inside the chart on the carpet represent the 36 digits. A single digit bet may be placed on any number on the table, including zero and double zero. Place your chip directly on the number, avoiding touching the lines. A figure pays 35 times the stake.
Horse (2 figures)
You can bet on 2 digits by depositing your token on the line adjacent to the two numbers for a winning opportunity of 17 times the bet.
Transversal (3 digits)
Place your token on the outer vertical line of a 3-digit series for a possibility of 11 times the bet.
Square (4 digits)
Also called “a corner”, the square forms the intersection of four numbers and reports 8 times the bet.
In European Roulette, you can bet the numbers 0, 1, 2 and 3 for a gain of 8 times your stake.
Many strategies have been put forward to reduce the casino advantage. Although players swear by some of them, these strategies are more or less valid, although brilliant, considering the risks involved. Different strategies can bring success in the short term. But in the long run, the house will always have an advantage. Here we present you some of them.
The idea of ??the Martingale is to multiply its stake by 2 after each loss. Thus, a gain of 1 token is almost inevitable. For example, bet 1 token. If you lose, bet 2. If you lose again, bet 4, and so on. The hitch: a player using this method must have a huge amount on him since it is possible to lose 10 times in a row, in which case the bet would be 512 chips. And all this for a gain of a single chip. Not to mention that the house imposes a maximum limit of the bets.
Following the same principle as that of her little sister, the Great Martingale adds one unit to the double. The bets would then be as follows: 1-3-7-15-31, etc. Again, the chances of loss are much greater than the gains.
The D’Alembert system
Jean Le Rond D’Alembert, an 18th century mathematician, is the author of this system, which consists of increasing his stake by one unit after each loss, and reducing it by one after each gain. Without having to bet a fortune, the player increases his winnings in relation to a bet of a single unit at any time. For example, lose 3 times in a row for 6 tokens (1 + 2 + 3 = 6), win the next 3 wagers for 9 (4 + 3 + 2 = 9) a net gain of 3 tokens. The problem is that chance dictates this game and that the ball may fall on the red (or black) 20 times in a row, or 40 times out of 50. Again, the player may have to invest large sums.
