Each roulette table moves in sessions, each session is associated with a spin of the wheel and that spin's result. 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. 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. Most roulette sessions move at a fairly slow pace, to accommodate the number of people betting, and the variety on which they can bet. If you have a player you likes to put down twenty different bets each time they play, the sessions are going to move a little slower. At this point, as you intuition may have mentioned to you, you can't place any more bets. The outside bets on a roulette board are simply the bets that reside 'outside' of the main playing area of 38 numbers. When you place an outside bet your bet must meet the table minimum. 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)

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. you will likely lose money faster the more bets you make, because you're betting more. 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". Then he'll scoop up all the losing bets towards the dealer area. 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. Sometimes the dealer will ask you "Inside or Outside? Roulette games have minimum bets, which will be posted on a placard at the table. 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! If Black has come up for the last 10 spins in a row, the next spin is not more likely to be Red. " That means it doesn't know what it spun before, and even if it did, the wheel can't select what number comes up out of its own volition. 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. 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. On an American wheel, there are 38 spots - numbers 1-36, plus 0 and 00. Your odds of winning a one-number bet are 37 to 1 (37 ways to lose, 1 way to win) 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. If you win the second spin, your bet is "released from prison" and you get it back.
