Roulette has offered glamour, mystery and excitement to casino-goers since the 17th century. It may look like a simple game to play, but there’s a surprising depth of strategy for serious players.
The game is played with a wheel that contains compartments numbered from 1 to 36, alternately red and black. A small ball is spun around the wheel and, if the ball settles in one of the pockets with a number that the player has bet on, the player will win. The odds of winning vary depending on the type of bet made. Players can bet on a single number, various groupings of numbers, the color red or black, whether the number is odd or even, and many other combinations.
A roulette wheel is constructed of a solid wooden disk slightly convex in shape with a metal rim. The rim has thirty-six compartments, painted alternately red and black and numbered nonconsecutively from 1 to 36. On European-style wheels, a 37th compartment, painted green, carries the sign 0; on American wheels two green compartments on opposite sides of the wheel carry the signs 00 and 0.
Each time a bet is placed, the dealer will spin the wheel and then place a ball into one of the compartments. Once the ball has come to rest in a pocket, the dealer will pay out any winning bets. The chips won in a winning bet are the property of the player and will not be returned unless requested otherwise.
Roulette was derived from the older games of hoca and portique and was first mentioned under its current name in 1716 in Bordeaux, France. The game rapidly gained popularity in casinos and gambling dens throughout Europe.
Some people attempt to beat the house by using a variety of strategies, some legal and some illegal. The most common method involves predicting the location of the ball after a spin, but it is difficult to accomplish. The casinos are aware of this and do not welcome this type of cheating, but some players will still try to gain an edge.
To maximize your chances of success, it is important to start with a well-established bankroll. Set a budget for your session, and stick to it. Then, determine the size of your betting unit based on the amount of money you have available. For example, if you have five units, you should bet one unit on D’Alembert. As you win and lose, adjust your bet size accordingly. This will prevent you from losing too much and also help you make a profit if your strategy is successful. If you don’t have enough money to bet a full unit, you can begin by placing a bet on the outside of the table (street bets). These bets require fewer chips than inside bets and have a lower house edge.
