The first thing you should know before you learn anything about the bets you can make, is when and how you can make those bets. After the ball has started spinning, the dealer will wave his hands across the table and say 'no more bets'. 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. Fiver number bet - there is only one five number bet available. 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. This is different than inside bets, where the total of all of your inside bets must meet the table minimum. 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)

Roulette is the game where you guess where the little marble is going to drop on the spinning wheel. 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. 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. Sometimes the dealer will ask you "Inside or Outside? If you're asked Inside or Outside, always answer "Both", even if you only intend to bet one or the other. 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. Minimum bets work differently for inside and outside bets. It's important to understand that the outcome of the roulette wheel is truly random. You can certainly switch to another number if you want, but that won't improve or worsen your chances. if you win, the casino doesn't pay you 37 to 1, they pay you less - 35 to 1. The European wheel has a lower house edge (2.63%) because it has only 37 slots instead of 38 (no 00) Atlantic City has a special rule which reduces the house edge to 2.7% on even money bets (Red/Black, Odd/Even, 1-18/19-36): If 0 or 00 comes up on on even money bet, you lose only half your bet. 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. You don't get paid for the win, though, but it's better than losing it outright.
