Dozens and Columns Roulette System

Dozens and Columns Roulette System

If you want to apply a strategy to roulette, you have several to choose from — and the Dozens and Columns approach is massively popular.

However, unless you’re a seasoned roulette player, learning to use any system can be tricky. What does the Dozens and Columns roulette system involve? What do you need to know to start using it at real and virtual tables?

In this guide, we’ll cover everything you need to know about the Dozens and Columns system in roulette.

What is the Dozens and Columns Roulette Strategy?

The Dozens and Columns system involves placing either Dozen or Columns bets on a roulette table. 

First, let’s look at the numbers on a standard table. Depending on the variant you’re playing, a table has either 37 or 38 numbers: 1 - 36 with a single zero for French and European roulette, or a double zero for American roulette. 

The numbers are arranged in a long grid, with three columns: 

  • Column 1 — 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34 
  • Column 2 — 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35
  • Column 3 — 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36

The grid is split into three groups of dozens: 

  • Dozen 1 — 1 - 12
  • Dozen 2 — 13 - 24 
  • Dozen 3 — 25 - 36

When using the Dozens and Columns system in roulette, you have six bets to choose from. Each bet covers a dozen numbers, which is around a third of a roulette wheel. 

That’s essentially it: you pick any of the Dozens or Columns and place your bet. However, it’s up to you to decide which of the six available bets you take. You might choose to stick with the same Dozen or Column across each spin in one session, or you may diversify it by switching from spin to spin.

Odds in Dozens and Columns Roulette System

Odds are a crucial consideration when you start using any strategy, whether it’s fairly simple (like the Dozens and Columns system) or more complex. In some cases, working out the odds and weighing them up can be difficult.

Fortunately, that’s not the case with the Dozens and Columns system in roulette.

Each bet offers the same odds and a 2:1 payout. Wager £2 on a winning Dozen or Column bet, and you’ll get £6 (your initial bet plus £4).

When wagering in roulette, the Dozens and Columns system is more likely to create wins than bets that cover fewer numbers (inside bets). However, the payouts awarded for Dozens and Columns tend to be lower than those on offer with inside bets.

Dozens and Columns Roulette Systems Review

While reviewing the Dozens and Columns system in roulette, one factor we found fascinating was the flexibility on offer. You can take different approaches when using a Dozen or Column bet.

For example, one option is to wager on a Dozen with a Martingale structure. You might start wagering on the second Dozen, say, at £1 each time (or less if you want to make your bankroll last as long as possible). You increase the bet after each losing spin.

If you bet £1 on the first two spins and lose, you would up your bet on the third spin to £2, then £3 on the fourth spin, £4 on the fifth, and so on. But you would reduce your bet back to the starting amount after a winning spin.

The issue with this approach, though, is that the potential for losses increases with each spin, and wins can be on the low side. It’s also vital to keep the house edge in mind: the casino’s advantage, given the presence of the zero or double zero on the wheel.

Another approach to the Dozens and Columns roulette system to wager on two Dozens simultaneously. That means you would cover 24 numbers in total, which is a substantial section of the table, but if you use the Martingale method, the potential for high losses increases.

Final Thoughts

The roulette Dozens and Columns system is one of the simplest to understand and use. You can wager on 12 numbers at a time in a Dozen or Column, which covers large areas of a roulette table. The 2:1 odds are also straightforward.

There’s some flexibility with the Dozens and Columns system in roulette, too. You can change up your approach from game to game, or from spin to spin, depending on how you prefer to bet.

However, remember that roulette is always a game of chance, and there’s a house edge to consider that puts the casino at an advantage. Gamble responsibly with each spin, and set yourself a clear bankroll before you start playing.
