Strategy to Use When Betting on the Dozens

Having a betting strategy is key to have a successful and enjoyable roulette gaming experience. If you think playing roulette is for you, then you might want to consider implementing some set of betting systems that you need to use every time you play the game. Otherwise, if you’re just in an online roulette casino to splurge money and get high with the excitement, while at the same time hope that your money will return, then this post may not apply to you.

In this article, we’re going to talk about this particular strategy that if executed correctly, might earn you lots of profit per session. This is called Betting on the Dozens.

Bets on Dozens

This bet is one of the most popular outside bets used by roulette players. Depending on the variant, the roulette betting table is divided into three sections as shown in the image below:

Basically, the Low Dozen has the numbers 1-12. The Medium Dozen, meanwhile, has the numbers 13-24. For the High Dozen, there are numbers 25-36.  For convenience, let us call each section as L (Low), M (Medium) and H (High) as we go along the discussion.

Another thing to note, this system is only applicable for use in an RNG (Random Number Generated) roulette game.

Using the Strategy

Betting on the dozens is easy to do. Here are the steps to follow:

  1. Without betting, press “spin” on the roulette wheel.
  2. Using a pen and paper, note as to which section the ball lands. Is it in L, M, or H?
  3. For the second time around, press “spin” and note down the result.
  4. Keep doing the same process for up to 7 times.
  5. Should a single zero or double zero comes out, record as it is.

What we are trying to do here is to find that “special sequence.” Simply put, it is a sequence wherein one section does not appear in five consecutive spins.

For example, you have this tally – L, M, H, H, M, M. In this case, L hasn’t appeared in the last 5 spins. If we arrived with this kind of sequence, then we have found our “special sequence.” So in the given example, we will wager on L.

We will bet on L until one of its numbers come up. However, we have a special betting pattern to follow. Basically, we move up our betting amount as high as it can go. Check out this chart below:

Bet # Bet Amount (£) Profit (£)
1 1 +2
2 2 +3
3 3 +2
4 4 +2
5 6 +2
6 9 +2
7 13 +1
8 20 +2
9 30 +2
10 45 +2
11 67 +1


For the strategy to be successful, make sure that you stick to the pattern and never deviate from it.

As soon as you win at any point of the cycle, STOP. Go back to the beginning and find that SPECIAL SEQUENCE again.

The money earned using this strategy may not be that much. However, slowly but surely, you’re grinding your way to amass considerable amount of profit.


In the case that we presented here, the probability for the ball to not land on one section is .675 or 67.5%. Meanwhile, the chance for the ball not to land on a section 11 times is only .008%.
