The Favorite Dozen System

Betting options on casino roulette games can be very different, and dozens are among the most popular options where players bet 1 to 12, 13 to 24, or 25 to 36, so you may want to use an online roulette dozen system to manage your bankroll and try to minimise the house edge. Depending on your preferences, you can try out The Favourite Dozen, Dozens and Columns, and Betting on Two Dozens. Keep in mind that these systems serve as a helping hand to plan your strategy and track outcomes in the long run, but they can’t serve as strategies which guarantee wins.

The Favorite Dozen System

In the Favorite Dozen betting system, you will need to have at least 40 chips to apply the strategy. This means that if the min bet is $1, your bankroll should be as huge as $40.

The Favorite Dozen system allows gamblers to receive decent winning. The expected profit from one session is 8-10 chips. At the same time you should remember that there is no betting system which guarantees winning. And the Favorite Dozen strategy is not the exception to this rule.

How to apply the Favorite Dozen system

All you need to do is place a bet on the dozen that occurred most often in the last nine spins.

  1. If 2 different Dozens occurred more than 4 times during the last 9 rounds, you should place your bet on the latest dozen.
  2. If 3 Dozens occurred 3 times during the last 9 spins, you should play once again and place your bet on the last dozen.

You should keep betting on a certain dozen until:

  1. You win
  2. You lose three rounds

Then, you need to select another dozen to place your bet. Surely, it is easier to do when you play in a traditional casino where you can skip betting rounds and observe the roulette wheel. However, you can also apply the system to online casinos. In this case, just place the smallest even money bet to minimise your risk.

Bet value

According to the Favorite Dozen roulette strategy, you should use the following progression during the first 6 betting rounds: 1-1-1-2-3-4. If you fail to win at least one time after six betting rounds, your next bet should be determined by the following factors:

  1. With the overall balance from -12 to -24, you need to divide the bet by 4 (and round off the figure if needed). For example, your overall balance is -16. In this case, divide 16 by 4, your bet will be $4.
  2. If the overall balance is between 0 and -11, you must divide by 3 and round off.
  3. If the overall balance is from -25 to -40, you must divide by 5 and round off.

The Favorite Dozen system in roulette seems to be a bit complicated. But in fact, the strategy works quite effectively. Try to apply it in practice mode first (fun money gambling). As soon as you understand the algorithm, you can switch to real money gambling.

Dozens and Columns roulette system

The Dozen strategy explained here is based on bets on columns and dozens at the same time. Both dozens and columns pay 2:1, and their bets can be combined since the same numbers are involved in the combination. If we are talking about European Roulette, columns include the following numbers:

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

Thus, you can choose a number which is within a certain column and place both bets. For example, you can bet on column one and the first dozen since you will win in both cases when the ball lands on numbers 1, 4, 7, or 10.

For example, when you bet $10 on column 1 and $10 on the first dozen of 1 to 12 when the ball lands on 1, 4, 7, or 10, you win $60, where $20 is your bet and $40 is your net winning.

Two Dozens betting roulette system

In this case, you must choose two dozens you will bet on. One of them will be the Main bet, and the other bet will be considered Secondary, the goal of which is to serve as 50% insurance and cover losses when the Main bet doesn’t win. The Main bet will be 100%, and the Secondary one will be 50% of its amount to serve as insurance. For example, $10 is the main bet on the 1 to 12 dozen and $5 on the 13 to 24 dozen as insurance.

According to the Dozen system in roulette, when the Main bet wins, you get $30, which will cover your $10 and $5 stakes and bring $15 as a net win. When the secondary bet wins, you get only $15, which can compensate for 50% of your Main bet. However, you should remember that there are three Dozen options in roulette, so you still don’t cover the third one when following this strategy.

Betting on Three Dozens roulette system

Alternatively, you can choose the Dozen roulette strategy based on stakes on all three dozens, which are 1 to 12, 13 to 24, and 25 to 36. The bets can be $20, $10, and $5, where $20 is your main bet you will focus on. This way, you spend $35 per round. When the main bet wins, you get $60, covering all the values of stakes of $35 and getting $25 as your net win. The other two bets will serve as compensation for a certain amount you lose when the highest bet doesn’t work. This way, you win in nearly all cases except for the rounds where the ball lands on the zero position.
