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. 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) 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. On inside bets, the total of all of your bets must add up to at least the table minimum. 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. There are the different types of outside bets.

Roulette is the game where you guess where the little marble is going to drop on the spinning wheel. 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. you will likely lose money faster the more bets you make, because you're betting more. Then he'll scoop up all the losing bets towards the dealer area. Don't reach for your winnings until the dealer removes the marker, or the dealer will scold you. 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. 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. Black and Red still have equal chances of hitting. You can certainly switch to another number if you want, but that won't improve or worsen your chances. The chances of #27 coming up on a given spin are the same, whether it just come up on the last spin or not - 1 in 38. It's more important to know what the house edge is, than how to calculate it, but here's a quick analysis in case you're interested. Your odds of winning a one-number bet are 37 to 1 (37 ways to lose, 1 way to win) The difference between the true odds and what they actually pay you is 2/38, or 5.26%. 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. You don't get paid for the win, though, but it's better than losing it outright.
