Column bets are very common and payoff at odds of 2/1.

There are three columns on a roulette table column 1-2 and 3.
Each column consists of 12 numbers excluding zero and double zero on an American style roulette wheel, leaving a grand total of 36 numbers 18 of which are red and 18 of which are black.

18 of these numbers are even and 18 are odd, however the columns do not have 6 red and 6 black numbers each.


Column 1 has 6 red numbers 1-7-16-19-25-34 and 6 black numbers 4-10-13-22-28-31.
Column 2 has only 4 red numbers 5-14-23-32 and 8 black numbers 2-8-11-17-20-26-29-35.

Column 3 as only 4 black numbers 6-15-24-33 and 8 red numbers 3-9-12-18-21-27-30-36.


The strategy here is: If you choose to make a wager on red and a column then by chosing column 3, your odds of getting paid out on both bets are increased if the ball drops in a number represented by column 3.
The chances of the number being red are 2-1 in your favour.

If you had bet red and column 2 your odds would be 1-2 against a double winner.
Column 1 would be Even.


The opposite applies when betting on black column 1.

Even column 2 would be 2-1 and column 3 would be 1-2 against a double winner.





INSIDE THE SWAG BAG


Betting on a color and a column at the same time using the information above will not improve your chances of winning. It will however give the maximum amount of winnings.
After all you are playing with the intent of making a profit so bet red and column 3, bet black and column 2.
