Roulette is one of the most popular casino games, particularly in Europe. It offers a high level of complexity for experienced players.

Roullete is a gambling game that is played on a wheel with numbered pockets or compartments around its rim. It was developed in France from the older games hoca and portique. The game has a relatively low house edge and draws big crowds, especially at European resorts such as Monte Carlo.

There are many different types of bets in roulette, including inside and outside bets. Inside bets are bets that cover a specific number or range of numbers based on their position on the roulette table.

Among these bets are ones covering all the red numbers or black numbers on the board, as well as other combinations of groupings such as odd or even, or a combination of both. The payouts for these bets vary according to the probability of the result, but are generally lower than those for straight bets.

The wheel of the roulette is a wooden disk with metal partitions called separators or frets, painted alternately red and black, numbered nonconsecutively from 1 to 36, and a green division numbered 0. American wheels have two extra green compartments on opposite sides of the wheel, numbered 0 and 00.

Before the spin, bettors place chips on a special betting mat that shows the precise location of their bets on the roulette table. Then, the dealer spins a wheel and drops a ball that moves through the various numbered sectors until it comes to rest in one of these divisions.

In the United States, roulette is often called American roulette. Unlike in European casinos, where the wheel is on the table, American tables use a special spinning wheel that spins on its own. The American version of the game is a poor financial proposition, though it has a larger following than its European counterpart.

To play the game, a player must select a chip colour and then a dollar value that reflects how much their bets will be worth on each spin. The player can choose to play a single chip or multiple chips depending on their bankroll.

When the spin is complete, the dealer removes a small symbol called a buck or puck from the table and places it on the table in front of the player. The dealer then rolls the buck or puck and announces which number it has hit on the previous spin.
