Roullete, or roulette in French, is a casino game that involves spinning a numbered wheel while a small ball spins around and bounces into one of the pockets that mark specific numbers. Players can choose to wager on a single number, various groupings of numbers (such as red or black), whether a number is odd or even, and the high or low value of those numbers. If the ball lands on your chosen number, you win!

The wheel consists of a solid wooden disk, slightly convex in shape. Around its rim are thirty-six compartments, painted alternately red and black and numbered nonconsecutively from 1 to 36; on European-style wheels an additional green compartment, carrying the sign 0 (or ) is included. In addition, some of the compartments are painted a different color to distinguish them from others and help make it easier for the ball to land in them.

Once the wheel is in motion, the croupier throws a small ball into the wheel and players can still be wrapping up their bets when the croupier announces “no more bets.” The ball spins and bounces until it lands into a pocket that marks a particular number. If you made a bet on that number, you win!

While there are many variations of roulette, most of them are similar in how they work. The key to winning is knowing the odds of each bet and using a system that maximizes your chances of success. The best way to do this is by learning about the different betting systems and strategies available for the game.

Before you play, decide how much you want to bet per round. Then, choose a table that fits your budget. Each table carries a placard that describes the minimum and maximum bets allowed. Most tables have a minimum bet of $5 and a maximum bet of $1,000 for outside bets. The minimum bet is typically lower for inside bets, because they offer higher payouts if you win.
