Columns and Dozens roulette system explained!

Columns and Dozens system

Red and black is one of the most popular betting systems used for roulette, followed by columns and dozens. The dozens go across the board and players normally find them easy to memorize. The columns can prove to be more difficult. The 0 and 00 slot is omitted from the rows and columns which means less than a third of the table is covered.

Strategy 1

Select any dozen and place a bet of 1. If you lose, simply employ the following sequence of numbers until you experience a win.

1, 2, 3, 4, 6, 9, 13, 20, 30, 45, 67 and 100.

If you win using any of the above numerical systems, you will end up with slightly more than you started with. Of course, there is a chance that you may not land on any of the above numbers, meaning that using this betting system could result in a loss. Another drawback of this method is that as you’re only covering under one third of the table, you will find that you end up losing more bets than you win, thus resulting in a losing streak.

Strategy 2

To cover a larger area of the table, you can try placing two simultaneously. Players should use the following progression.

1, 3, 9, 27, 81 and 243.

The reason for the large numbers towards the end is that bets need to be multiplied by three each time you lose. The plus side to this strategy is that you will be covering more than two thirds of the table. However, the steep progression means that losses can be accumulated quickly, ending with a large loss that can be difficult to come back from. Ever tried the famous Martingale system?
