Each roulette table moves in sessions, each session is associated with a spin of the wheel and that spin's result. 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. When the new session starts you can put your chips down where you want to bet, and you don't really have to be in a hurry. Just sit back and let the ball fall where it may. The outside bets on a roulette board are simply the bets that reside 'outside' of the main playing area of 38 numbers. This is different than inside bets, where the total of all of your inside bets must meet the table minimum. There are the different types of outside bets. 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. 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)

now, let's see how to play roulette. Making a bet is easy - you just place your chip(s) on the number(s), color, or sets you want to bet on. You don't have to make just one kind of bet for each spin, you can make several, and you win if the ball lands on any of your numbers. The house edge is the same whether you make one bet per spin or several. In most games players can continue making bets even while the ball is still spinning. When the ball is getting ready to drop, the dealer will wave his hand over the table, which means "No more bets". When the ball falls into a slot, the dealer will announce the number and the color, and place a marker on the layout where the winning number is. Don't reach for your winnings until the dealer removes the marker, or the dealer will scold you. That way if two players bet on the same number (or set of numbers), then the dealer knows who to pay, and arguments can't arise over who bet what. That way, you're not locked in and you always have the ability to change your mind. When you buy in, tell the dealer what denomination you want. Roulette games have minimum bets, which will be posted on a placard at the table. Minimum bets work differently for inside and outside bets. 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. There have been 152 spins (coincidentally, 4 x 38), and so we expect that each number should have come up 4 times on average. On an American wheel, there are 38 spots - numbers 1-36, plus 0 and 00. The European wheel has a lower house edge (2.63%) because it has only 37 slots instead of 38 (no 00)
