Roullete, also known as Roulette, is a gambling game in which players place bets on which number or grouping of numbers the ball will land in after it has come to rest in one of the compartments of a revolving wheel. Bets may be placed on either red or black, on odd or even numbers, or high (1-18) or low (19-36). Often, a player can choose to wager on several different aspects of the game at once by placing multiple chips on the betting mat.

In the modern game, a small ball is released in the opposite direction of a revolving wheel and as it slows down, a coloured marker indicates where it has stopped. The dealer then pays out winning bets and removes losing ones from the table. The game’s popularity stems from its relative ease of play and the glamour that surrounds it.

The game was first introduced in a primitive form in the 17th century, although it’s widely credited to a French mathematician and inventor, Blaise Pascal, who was trying to create a perpetual motion machine. The modern roulette wheel and table were developed a century later.

Unlike some other casino games, where the bets are made by hand, in roulette, players wager on numbers and groups of numbers that are written down on a special betting board. These bets are called ‘called bets’ and are unique to European and French Roulette.

Outside bets are the best choice for a beginner, as they offer the chance to win with lower odds and higher payouts than inside bets. The bets are placed on the outer edge of the betting grid, and include red or black, or odd or even numbers.

When you have won a bet, make sure to cash out your chips as quickly as possible. This will prevent you from using your winnings to cover losses, which can add up over time.

Before you play, decide on a budget and a maximum amount that you are willing to risk. You should also choose a table within this budget, and select an appropriate chip denomination. The roulette tables carry placards describing the minimum and maximum bets allowed, so check them before you begin playing. Also, remember that the roulette table is very noisy, so be prepared to hear other players making comments and shouting. This can affect your focus and distract you from making the most informed decisions.
