A game of chance played at a table marked off in various sections affording the players a variety of betting opportunities, having in its center a revolving dishlike device (the roulette wheel) into which a small ball is spun to come to rest finally in one or more of the compartments. The winning number and its characteristics, as odd or even, red or black, high or low, are indicated by a painted marker or a stencilled marking on the rim of the wheel.
The game has offered glamour, mystery and excitement to casino-goers worldwide since the 17th century. Though the game is relatively simple to play, there’s a surprising depth of strategy for those who take it seriously.
Unlike other casino games, which have a wide range of house edges, roulette’s are fairly stable. There are however a few different types of bets that have the potential to lower the house edge, some of which can be made only on even-money bets, such as column and dozen bets.
Other popular roulette bets include outside bets which are placed on groups of numbers rather than individual digits. These bets are usually cheaper and have a higher winning probability. It is also possible to place a tier bet, which is a bet on three consecutive numbers. If a player chooses to place this bet, they will have to pay for all of the tiers if they win.
European roulette is the most popular version of the game, both in physical casinos and online. It has a single zero pocket which reduces the house edge to a coveted 2.7%, making it more favorable than American roulette.
Several systems have been devised to beat the game, but none has proved foolproof so far. Those who have found some success have often employed a combination of strategies, such as the Martingale system, which advises you to make only even-chip bets. Alternatively, the Labouchere system requires you to set a desired amount of money you want to win and then alter your stake amounts depending on whether you’re losing or winning.
