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 you’ll be paid off at 6-to-1 and what do you think the casino advantage is on this bet? Nope, I gotcha… it’s 7.89%. Actually, this is the worst possible bet on the roulette table and the only bet you’ll come across that doesn’t 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 you’d 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, let’s 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?…that’s 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 that’s 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 you’ll 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 doesn’t.
