Roullete (also known as Roulette) is a casino game in which a ball is spun around the edge of a revolving wheel. Bets may be placed on a single number, various groupings of numbers, the color red or black, or whether the number is odd or even. The game originated in France at the end of the 17th century and quickly spread throughout Europe. Despite the numerous fanciful stories about its origin, roulette is essentially a simple game of chance.

Before the wheel spins, players place chips on a betting mat that corresponds to the type of bet they want to make. The chips are then picked up and deposited on the roulette wheel. Then, the croupier spins the wheel and a ball is rolled into one of the pockets on the roulette table. The pocket the ball lands in determines the winning number and payout. After the winning bets have been paid, the losing bets are removed from the table and the process begins again.

There are a few different types of bets in Roulette, each with its own paytable and odds. Inside bets are those that cover six or fewer numbers on the Roulette board. Outside bets, on the other hand, are those that cover twelve or more numbers on the board. Both bets have their advantages and disadvantages, but the odds of winning them are very similar.

The roulette wheel consists of a solid wooden disk slightly convex in shape. Around its rim are metal partitions known as separators or frets. The compartments on these are painted alternately red and black. On European-style wheels, a 37th compartment, called the zero, is also present. American roulette wheels also contain two green compartments, marked 0 and 00.

To play the game, a player must give the dealer a value of coloured chips. The dealer then gives the player a number of chips equal to the value of the bet. If the bet is successful, the player must then leave a marker on the winning number, and any remaining chips are left up to win again on the next spin of the wheel. The player should always play within their budget. This will ensure they have enough funds to complete the required wagering requirements before the bonus expires.
