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. All of your chips of the same color are worth the same amount. 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. Straight-up bet - this is the classic roulette bet. Choose any one of the 38 numbers and put your chips down on that number for the chance to win back at 35 to 1. Street bet - this is a bet not unlike a split. It allows you to bet on three different numbers with the same bet. When you place an outside bet your bet must meet the table minimum. There are the different types of outside bets. Odd or Even - similar to the red black bet, this even money bet is based on whether the resulting number will be odd or even. 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)

Roulette is the game where you guess where the little marble is going to drop on the spinning wheel. 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. Sometimes the dealer will ask you "Inside or Outside? Roulette chips can in fact be any denomination - $1, $5, $25, etc. Remember that you can bet inside or outside if you like; there's no requirement to bet both on a given spin. In this way, Roulette is more like slots - one single bet can win a lot. There have been 152 spins (coincidentally, 4 x 38), and so we expect that each number should have come up 4 times on average. 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. On an American wheel, there are 38 spots - numbers 1-36, plus 0 and 00. 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) The last time we checked, Single 0 Roulette was available at the Stratosphere and the Monte Carlo on the Vegas Strip. On even money bets when 0 comes up, instead of losing right away, your bet is "imprisoned" and rides again for the next spin. You don't get paid for the win, though, but it's better than losing it outright.
