If you haven't read up on the rest of the site I'll quickly go over the different colors of chips and how they relate to the rest of the roulette rules. You trade in your checks (which most people think of as regular casino chips, but they're actually called checks) for roulette chips when a new session starts, and the dealer assigns you a number and denomination. At this point, as you intuition may have mentioned to you, you can't place any more bets. Now lets take a look at each of the individual bets you can make. The outside bets on a roulette board are simply the bets that reside 'outside' of the main playing area of 38 numbers. There are no winning outside bets for 0 or 00 results. Odd or Even - similar to the red black bet, this even money bet is based on whether the resulting number will be odd or even. Low or High - this bet lets you predict whether you think the next number to come up will be part of the range from 1 to 18, or part of the range from 19 to 36. Columns - at one end of the set of 38 numbers are boxes with the words '2 to 1' written in them. Dozens - a bet very similar to the columns bet, dozens lets you place a bet on either the first dozen numbers (1-12), the second dozen (13-24), or the third dozen (25-36)

Roulette is the game where you guess where the little marble is going to drop on the spinning wheel. Roulette would be a great game were it not for the high house edge - usually 5.26%, sometimes as low as 2.63%, which is still higher than blackjack, craps, or baccarat. Here are the different bets you can make. Don't reach for your winnings until the dealer removes the marker, or the dealer will scold you. New players often have to be told this repeatedly the first time they play because they kept forgetting and because they're excited about collecting their winnings. That's because if you're betting only inside and someone else is betting only outside, he can give you both the same color chips and there won't be any confusion. Roulette games have minimum bets, which will be posted on a placard at the table. For outside bets, any bet you make has to be the table minimum. Inside bets can usually be as small a you like, as long as the total of all your inside bets is the table minimum. It's important to understand that the outcome of the roulette wheel is truly random. Here's another example: Since there are 38 slots on the wheel, we expect any given number to hit 1 out of 38 spins on average. The wheel has no memory. You can certainly switch to another number if you want, but that won't improve or worsen your chances. The chances of #27 coming up on a given spin are the same, whether it just come up on the last spin or not - 1 in 38. The difference between the true odds and what they actually pay you is 2/38, or 5.26%. On even money bets when 0 comes up, instead of losing right away, your bet is "imprisoned" and rides again for the next spin. If you win the second spin, your bet is "released from prison" and you get it back.
