# The Basics of Roulette

Roulette is a casino game based on chance. There are many different types of bets that can be made, including those on individual numbers, groups of numbers, whether they’re odd or even, and if the number is high or low. The game’s origin is uncertain, but it is generally accepted that it was invented by 17th-century French mathematician Blaise Pascal or by a Dominican monk, and that it may have been derived from the older games hoca and portique.

The game is played using a wheel, a betting table, and a ball. The wheel is a solid, slightly convex disk with 37 or 38 compartments (called frets or canoes by roulette croupiers) that are painted alternately red and black and numbered from 1 to 36. On European roulette wheels a green compartment carries the numeral 0; on American wheels two additional green compartments, labeled ‘double zero’, are also present. The wheel is spun and the ball is dropped into one of the pockets; whichever one it lands in determines which bets win and which lose.

When playing roulette online, you’ll use the in-game chips to place your bets. You can make multiple bets by clicking on sections of the betting table before confirming your selection. You have a limited amount of time to place your bets, after which the dealer will spin the wheel and drop the ball into one of the 37 pockets. Winning bets will then be paid out and the losing bets will be cleared off the table.

There are various strategies you can use to improve your chances of winning at roulette, including the Martingale system and the Labouchere system. The former involves doubling your stake every time you lose; the latter requires that you change the size of your bets depending on how much you’re winning or losing.

If you bet on a single number and it wins, you’ll receive 35 times your original stake. This is the closest thing roulette has to a jackpot. However, you’ll still lose your even chip bet if the ball falls on zero. A split bet on the two zeros is a more reliable option, but it doesn’t pay out as well.
