Roullete (or roulte) is a casino game played on a table marked off with various groupings of numbers and one or two zeros, providing players with a number of betting options. A small ball is spun around the rim of a revolving wheel, and when it comes to rest on a number, the player who betted on that number wins. Players may also bet on the color of the number – red or black – or whether it is odd or even.
The rules of roulette are simple and the gameplay is easy to learn. To start playing, players place their chips on the table in the desired bet amounts. Then the spin button is pressed and the wheel is spun. The winning number is determined in a matter of seconds, and payouts are automatically granted.
There are several variants of the game, but all feature a table, a revolving wheel with numbered pockets, and a ball that spins around until it stops on a number. The game’s history is largely unknown, although legends have it that it was invented by a 17th-century French mathematician named Blaise Pascal and by a Dominican monk. In any case, it is a popular casino game in many countries.
In the USA, American Roulette is available online at casinos and in land-based establishments. It has a slightly higher house edge than the European version because of the presence of two green pockets, representing 0 and 00. In addition to the standard 38 red and 18 black pockets, this makes the odds of hitting a straight bet 37:1, while it pays 35:1.
Players can choose from different types of bets, which fall into two categories: Inside and Outside. Inside bets are those placed on individual numbers, while Outside bets are those positioned on groups of numbers forming squares or rectangles. Some examples of these bets include a Straight bet, which is made by placing the chips on the number; a Split bet, which places the chips on two adjacent numbers; and a Corner bet, which is a wager that one of four consecutive numbers forming a square on the betting board will win.
