A session ends when the ball lands where it may, and the dealers clear the board of losing bets (and pay winning ones of course) 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. All of your chips of the same color are worth the same amount. Most roulette sessions move at a fairly slow pace, to accommodate the number of people betting, and the variety on which they can bet. After the ball has started spinning, the dealer will wave his hands across the table and say 'no more bets'. Just sit back and let the ball fall where it may. Corner bet - lets you bet on four adjoining numbers. Placing your chips at the point where four numbers meet will indicate you want a corner bet. Red or Black - you can choose to bet on the outcome either being a red number, or a black number. 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)

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. That way, you're not locked in and you always have the ability to change your mind. There's no advantage to limiting yourself to inside or outside. In other games the color of the chip denotes the denomination, but in Roulette the color denotes only which player the chip belongs to. Roulette chips can in fact be any denomination - $1, $5, $25, etc. When you buy in, tell the dealer what denomination you want. Here's a handy way to remember the payouts when you're betting on a set of numbers: Take 36 divided by the quantity of numbers you're betting on, and subtract 1. All the bets on the layout carry the same house edge, with the exception of 5-number Line Bet (0, 00, 1, 2, 3), which carries a whopping 7.29% edge! It's important to understand that the outcome of the roulette wheel is truly random. Now let's say you've been playing Roulette for a few hours, betting on Red every time, and you've been keeping track of what numbers have hit. The European wheel has a lower house edge (2.63%) because it has only 37 slots instead of 38 (no 00) European games have an option called en prison which reduces the house edge to 1.35%, but it's generally not available in the U.S., even in casinos that use the European wheel.
