How to use the Labouchere Strategy for Roulette

If you want to preserve your bankroll in Roulette, then you should consider using the Labouchere Strategy. This type of betting strategy will allow you to safely control the increase of your bets while giving you an “exit” strategy to end a session with a profit.

How does the Labouchere strategy work?

The Labouchere strategy involves starting with a sequence of five numbers that will represent your betting size. The five numbers can be sequential.
Or you can use the same five numbers in a row.

For the first


we will use the 1-2-3-4-5 example. Let’s say each number equals $5 a unit. So the number “1” will equal a $5 bet while the number “5” will equal $25. In the Labouchere strategy, you will add the first and last numbers of the sequence to make up your first bet.
First bet 1 + 5 = 6 x $5 = $30

So, your first bet is $30. We would recommend that you use these bets in the 50/50 wagers on the roulette table. So you will want to be either red or black, even or odd, or 1-18 or 19-36 numbers. Betting this will give you about a 46.70% chance of winning your bet.

If your first bet wins, then you will eliminate the “1” and the “5” from your sequence, leaving you with the 2-3-4 numbers. So, your next bet will be:
2+4=6 x $5 = $30

Your second bet will be $30. If you win that bet, then you will eliminate the “2” and the “4” leaving you with the number 3
3 x $5 = $15

Your final bet will be $15, if you win that bet, you are done! Your total winnings will be $75 for winning three bets in a row.

Now, let’s say your first bet loses. Instead of removing numbers from your 1-2-3-4-5 sequence, you will add another number. This number will be progressively larger and added to the end of the sequence

After losing your first bet of $30, your next bet will add the “1” plus the “6” numbers:
1+6=7 x $5= $35

So you can see your bet increases but it doesn’t radically double in size like a Martingale betting strategy. This allows you to preserve your bank roll.

Which betting size should I use?

As stated before, you can use several different types of sequences. If you are afraid of going on a losing streak and increasing your bets too high, you should just use the same number in your sequence.

In this case, your first bet will add the first number “10” plus the last number “10.” We will use a $1 betting unit in this case.
10 + 10 = 20 x $1 = $20

If you win your first bet, you will eliminate the first and last “10,” leaving you with this sequence 10-10-10. Now, your second bet will also take the outside numbers.
10 + 10 = 20 x $1 = $20

Of you win your second bet, then your sequence will be down to a single 10 number. Your final bet will look like this.
10 x $1 = $10

If you win three bets in a row, congratulations, you finish the sequence a winner. Your total winnings will be $50.

Now, let’s look at this sequencing with losing bets. Like the previous example, if you lose your first bet, you will add another 10 to your sequence so it looks like this.

You will take the two outside numbers for your second bet, which will give you the same wager as before.
10 + 10 = 20 x $1 = $20

Which sequence should I use?

If you have a larger bankroll, then you should consider using progressive sequential numbers in your Labouchere System. Here are some examples.

  • 1-2-3-4-5
  • 2-4-6-8-10
  • 2-4-8-16-32

If you don’t have a big bankroll, then you should stick to using the same number in your sequence.

Using the same number, in a Labouchere System, will keep you making the same bet amount until you get to the final bet which will be 50% of the other bets. In this case, you are using the Labouchere System to simply give you strategy to end your session.

How much of a bankroll should I use for each Labouchere Strategy?

For a Labouchere Strategy, you should have at least two times the total numbers in your sequence times your unit size. So for instance, if your sequence looks like this.

Then add all the numbers
1 + 2 + 3 + 4 + 5 = 15 x 2 = 30

Now take that number and multiply it by your unit size. For this example, let’s say your unit size is $5.
30 x $5 = $150

This bankroll size will allow you to lose about four bets in a row before your bankroll is depleted. Using 50/50 bets (red/black, even/odds, 1-18/19-36) you have a slim chance of busting out of your bankroll in the first four rolls of the roulette wheel.

  • Odds of losing one bet in a row: 53.5%
  • Odds of losing two bets in a row: 26.75%%
  • Odds of losing three bets in a row: 13.375%
  • Odds of losing four bets in a row: 6.6875%

Summing it all up

  • The Labouchere Strategy can help you safely manage your bankroll and end your session with a profit.
  • You will start with a sequence of five numbers.
  • Your first bet will add the first and last numbers to the sequence,
  • If you win your bet, you eliminate the first and last numbers of your sequence.
  • If you lose your bet, you will add a number to the end of the sequence.
  • To calculate your starting bankroll, add all the numbers to your Labouchere sequence, then multiply by two. Finally, take that number and multiply it by your betting unit size.
