Roulette, French for little wheel, is one of the most popular casino games. Its relatively simple rules make it easy to learn, but it also offers a surprising level of depth for serious bettors. The game is all about correctly guessing which pocket a small ball will land in after the dealer spins the wheel. There are several types of bets, and they can be placed on individual numbers, various groupsings of numbers, colors, whether they’re odd or even, and if they’re high or low.
A number can be a single color or combination of red and black, or it can be odd or even. Some bets, known as outside bets, cover groups of numbers such as the first 12 or second 12. Other bets, called inside bets, are placed closer to the wheel. These bets have higher payouts but lower odds of winning.
The house edge on most bets is 2.70%, but the La Partage rule lowers this to 1.35%. The dealer divides all even-money bets into half, keeping the house’s half and giving the player the other. The only bets that don’t benefit from this are the bets on the green zero or 00, which lose if they win.
When a player places a bet, the dealer will mark the chips with their color to indicate the denomination they represent. This helps to prevent cheating by preventing players from placing additional bets after the dealer announces “no more bets!” This is particularly important when a player has already placed all of his or her money, but it’s also an excellent way for dealers to avoid being cheated.
In the past, roulette balls were made of ivory, but today most professional roulette wheels use polycarbonate or Teflon. The size, weight and material of the ball impact the game, as a smaller, lighter ball makes more revolutions on the wheel before it lands, and jumps more unpredictably around the track when it does land.
Some bettors like to watch their opponents, hoping that they’ll pick up on something that others don’t, or to place their bets opposite those of other players in the hopes that they can skew the odds in their favor. But while such bets may help to keep the game interesting, they’ll never improve a player’s odds of winning more than by luck alone.
