Amongst various outside betting options in roulette, the ‘Dozens’ bet provides a fascinating blend of risk and reward potential. This bet type is part of a broader family of outside bets, including Red/Black, Odd/Even, Low/High and Columns bets.

What is a Dozens Bet in Roulette?

A Dozens bet in roulette is an outside bet where a player places a wager on one of three groups of dozen numbers: 1-12, 13-24 and 25-36. It’s a popular choice amongst players as it covers a fair amount of roulette numbers, while offering potentially decent returns.

Outside Bet
A bet on one of three groups: 1-12, 13-24, 25-36
On the 1st 12, 2nd 12, or 3rd 12 space.

How to Play Roulette Using a Dozens Bet

To play a Dozens bet, you place your chips in one of the three boxes marked ‘1st 12’, ‘2nd 12’ and ‘3rd 12’. If the ball lands on a number within the range you have chosen, you win.

While there is no foolproof betting strategy when it comes to playing roulette, players often use systems like the Martingale or Paroli betting strategies with Dozens bets, aiming to manage their bankrolls and leverage solid win streaks.

Is Dozens Betting Profitable for Roulette?

The payout on offer for the Dozens bet is 2-1.

The win probabilities are as follows:

  • European Roulette - 32.43%
  • American Roulette - 31.58%

Both versions of roulette possess a house advantage with this wager - 2.7% for European Roulette and 5.26% for American Roulette.

When it comes to placing this bet, if you decide to place a £10 bet on the 1st dozen and the ball lands on 7, you will win. The payout is 2-1, so you will receive winnings of £20, as well as your original £10 bet.

  • The payout of 2-1 is higher than the even money outside bets

Cons of Dozens Bet:

  • The win probability is lower than the even money outside bets
