Dozens And Columns

What Is It?

Red and Black count among the most common Roulette betting system there is. A close second would probably be the Dozens and Columns. There are three different dozens present on the roulette table – the first 12, the second 12, and the third 12. There are three column bets, the first of which covers from 1 to 34, the second covers from 2 to 35, and the third covers 3 to 36.

This gives the players 6 bets, each covering 12 numbers and having the same odds on every spin. The payout is 2:1 which means if you are planning to bet $1, you will win $3. The minimum table limit usually is 10p.

The Strategy

There are several ways you can play with this strategy. One way would be to choose dozen and bet $1 (or you can even bet 10p, whatever you are comfortable with). If you lose, follow the sequence given below till you land a win.

1 – 1 – 2 – 3 – 4 – 6 – 9 – 14 – 21 – 31 – 47 – 70 – 105 – 158 – 237 – 355

As long as you hit a win with any on these numbers, you will make a profit. The drawback here is that if you are unlucky and you do not get a win, you will be facing quite a big loss. Over long-term play, you will be losing more bets than winning as you are covering only one-third of the table with this strategy. There have been scenarios where there have been more than 30 spins without even one hitting a dozen or a column. If this happens, you will lose big time. You can test this theory out in any of the free online casinos. What you can do when you find yourself in such a situation is to wait for a few spins, maybe 10 or 20 and then start again. This will not alter the odds but you might be lucky enough to hit a win.

Another strategy is to bet on two dozens at the same time. When you do this, you will be covering more of the table. The progression you will have to use is:

1 – 3 – 9 – 27 – 81 – 243

Since you need to multiply your bets by three every time you lose, the numbers tend to grow bigger quite fast. On the brighter side, since you are covering more of the table, you will be getting more wins than losses. But with such a steep progression, a few losses are more than enough to sink you. You can also try waiting for a while and then bet. However, this does not change the odds.


Dozens and Columns is one of the easiest roulette strategies available. It is simple to understand and easy to execute as long as you remember the progression. If you have limited resources, it is better to start with the lowest available limit to keep it from escalating dramatically. As with any strategy, choose a stop limit and decide to walk away if you do not catch a win.
