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. There are no winning outside bets for 0 or 00 results. When you place an outside bet your bet must meet the table minimum. 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. Red or Black - you can choose to bet on the outcome either being a red number, or a black number. 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)

You should always calculate your expected loss and how long you can play on a given bankroll before playing any game, but with roulette it's especially important. For most bets it's fairly obvious - you can't miss the Red diamond for Red bets, and things like Even, 1-18, and 1st 12 are written out in plain English. We've added blue circled letters to the diagram to point out how to make the not-so-obvious bets (the sets of 2-6 numbers) The house edge is the same whether you make one bet per spin or several. When the ball is getting ready to drop, the dealer will wave his hand over the table, which means "No more bets". Each player's chips are a different color. 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. Roulette chips can in fact be any denomination - $1, $5, $25, etc. 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. In this way, Roulette is more like slots - one single bet can win a lot. 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! There have been 152 spins (coincidentally, 4 x 38), and so we expect that each number should have come up 4 times on average. Your odds of winning a one-number bet are 37 to 1 (37 ways to lose, 1 way to win)
