The overwhelming majority of American casinos use a double-zero Roulette wheel. This wheel has pockets numbered from 1 to 36, plus 0 and 00, for a total of 38 pockets. Contrarily, in Europe a single-zero wheel is commonly used and Roulette has always been the most popular game in the casino.
There are usually six seats at the Roulette table. In order to help the dealer differentiate each playerís bet, every player is assigned a different color chip, which they purchase right at the table. Each table has its own minimum chip values and that information is usually posted on a sign at the table. As an example, letís say a table has a $1 minimum chip value. This means that when you give the dealer your money the colored chips he gives you in return must have a minimum value of $1 each. Thus, if you gave the dealer $50 he would ask what value you wanted on the chips and if you said $1 he would give you 50 colored chips.
If you prefer, you could say you wanted the chips valued at $2 each and he would just give you 25 chips rather than 50. You can make the value of your colored chips anything you want and youíll notice that when the dealer gives you your chips heíll put one of your chips on the railing near the wheel with a marker on top to let him know the value of your chips. Later on when youíre done playing at that table you must exchange your colored chips for regular chips before leaving. The colored chips have no value anywhere else in the casino so donít leave the table with them.
Besides the minimum chip value, there is also a minimum amount that must be bet on each spin of the wheel. Once again, the minimums are probably posted on a sign at the table and if it says $2 minimum inside and $5 minimum outside this means that if you are betting on any of the 38 numbers that pay 35-to-1 the total of all your bets must be $2. You could make two different $1 bets or one $2 bet, it doesnít matter except that the total of all your bets on the numbers must be at least $2. The $5 minimum outside means that any of the outside bets that pay 2-to-1, or even money, require that you bet $5 each time. On the outside bets you canít make a $3 bet and a $2 bet to meet the minimums - you have to bet at least $5 every time. After youíve exchanged your cash for colored chips youíre ready to place your first bet so, letís see what your options are:
You can make a straight bet where you only bet on one number and if it comes in youíll be paid 35-to-1. The casino advantage on this bet is 5.26% and by the time youíre done with this roulette section Iím sure youíll be very familiar with that number. Another choice you have is to do a split. This is where you put a chip on the line that separates two numbers. If either number comes up youíll be paid at 17-to-1. The casino advantage on this bet is 5.26%.
If you put a chip in an area that splits 4 numbers this is called a corner bet and if any one of those 4 numbers comes in you will be paid off at 8-to-1. The casino advantage on this bet is 5.26%.
If you put a chip at the beginning of a row of 3 numbers, this is called a street bet and if any one of those 3 numbers shows up you will be paid off at 11-to-1. The casino advantage on this bet is 5.26%.
You can also put a chip on the line between two streets so that you have a double street covered and if any one of those 6 numbers come in youíll be paid off at 5-to-1. The casino advantage on this bet is?... you guessed it...5.26%.
The only other bet you can make on the inside numbers is the 5- number bet where you place one chip in the upper left corner of the number 1 box. If any one of those 5 numbers comes in youíll be paid off at 6-to-1 and what do you think the casino advantage is on this bet? Nope, I gotcha... itís 7.89%. Actually, this is the worst possible bet on the roulette table and the only bet youíll come across that doesnít have a 5.26% house edge on the double-zero roulette wheel. You should never make this bet.
One quick word here about "to" and "for" when discussing odds. Whenever the odds are stated as "to" this means that in addition to the stated payoff you also receive your original bet back. In other words, if you won your single number bet in roulette you would receive 35-to-1, which is a 35-chip payoff, plus youíd still keep your original one-chip bet, so you end up with 36 chips. Now if the odds are stated as "for" that means you do not receive back your original bet. If the odds in your single number bet were 35-for-1 you would still receive a 35-chip payoff but the casino would keep your original one-chip bet so you would only end up with 35 chips. The only place in a casino where the odds are always stated as "for" is in video poker. You might also come across it on a couple of craps bets where the odds are stated as "for-one" rather than "to-one" in order to give the casino a slightly better edge.
Now, getting back to our roulette examples, letís look at all of the outside bets that you can make and keep in mind that the house edge on all of these outside bets is...do you remember the number?...thatís right...5.26%.
There are three bets you can make that will pay you even money, or 1-to-1, which means that if you win, you will get back one dollar for every dollar you bet:
Red or black - If you put a chip on red then a red number must come up in order for you to win. If the ball lands on a black number, 0 or 00 - you lose. The same thing goes for black - you lose if it comes in red, 0 or 00 and you win if the ball lands on a black number.
Odd or even - If you put a chip on odd then the ball must land on an odd number in order for you to win. If it lands on 0, 00, or an even number - you lose. If you bet on even, you win if an even number shows up and lose if the ball lands on 0, 00 or an odd number.
1 through 18 and 19 through 36 - If you bet on 1 through 18, then you win if a number from 1 through 18 comes in and you lose if the ball lands on 0, 00 or a number higher than 18. Similarly, if you bet on 19 through 36, you win if one of those numbers comes in and you lose on 0, 00 or any number lower than 19.
The only other bets left are the dozens and columns bets. If you look at the roulette betting layout you can see three areas that each correspond to 12-number sections on the table. The one marked 1st 12 covers the numbers from 1 to 12, the one marked 2nd 12 covers the numbers from 13 to 24 and the other one thatís marked 3rd 12 covers the last section of numbers from 25 to 36. If you bet on the 1st 12 you would win if a number from 1 to 12 came in and you would lose if anything else came in, including 0 or 00. The same principle holds true for each of the other dozen bets where you would win if a number in that section came in and you would lose if anything else showed up. All dozens bets pay 2-to-1.
The last bet to look at is the column bet and that is also a bet that pays 2-to-1. There are three possible column bets you can make and youíll notice that each area corresponds to the numbers in the column directly above it. So, if you put a chip under the first column you will win if any of the numbers in that column come in and you will lose if any other number, including 0 or 00 shows up. Once again, the same rule is in effect for each of the other columns where you would win if the number appears in the column above your bet and you would lose if it doesnít.
