Roulette is an iconic game of chance in casinos around the world. With simple yet exciting rules, Roulette attracts both new and professional players. However, to increase the chances of winning and manage capital effectively, players often apply betting strategies. In this article, in 999 will introduce the 5 most famous Roulette strategies, including: Martingale, Fibonacci, Labouchère, D’Alembert and James Bond — each strategy has its own advantages and disadvantages to suit different playing styles.
1. Martingale Strategy – Double After Every Loss
How it works:
Martingale is the most popular and easy to apply betting strategy. Players start with a small bet on options that have a winning rate of nearly 50% such as red/black, even/odd. If you lose, you double your bet for the next round. When you win, you recover all the lost capital and make a profit equal to the original bet.
For example:
Bet 10,000 VND on red, lose
Bet 20,000 VND on red, lose again
Bet 40,000 VND on red, win ⇒ profit 10,000 VND
Advantages:
Suitable for beginners
Easy to understand, easy to implement
Effective when the losing streak is not too long
Disadvantages:
High risk if the losing streak is long
Easy to “burn a hole in your pocket” if there is no betting limit
Need a large capital to pursue
2. Fibonacci Strategy – Based on the famous number sequence
How it works:
This strategy is based on the Fibonacci number sequence: 1, 1, 2, 3, 5, 8, 13,… Players will bet in order of the number sequence, and after each loss, increase the bet to the next number. When you win, you will go back two steps in the sequence and continue.
For example:
Bet 10,000 VND → lose → next 10,000 VND → lose
Bet 20,000 VND → lose → bet 30,000 VND → lose
Bet 50,000 VND → win ⇒ return to 20,000 VND
Advantages:
Safer than Martingale
Losing many times still has a chance to break even
Better risk management
Disadvantages:
Easy to get confused if not closely following the number sequence
Not effective if the winning streak is not timely
3. Labouchère Strategy – Sequence of Numbers and Controlling Profit Target
How it works:
Labouchère (also known as Split Martingale) is a strategy in which the player sets a profit target in advance by creating a sequence of numbers (e.g. 1-2-3-4). The bet is calculated by the sum of the first and last numbers in the sequence. If you win, remove those 2 numbers; if you lose, add the bet to the end of the sequence.
Example with 1-2-3 sequence:
Bet 4 (1+3) → lose → new sequence: 1-2-3-4
Bet 5 (1+4) → win → remaining sequence: 2-3
Bet 5 (2+3) → win → sequence ends ⇒ reach target
Advantages:
Actively set profit target
Optimize capital management
Suitable for patient, calculating players
Disadvantages:
Complicated for beginners
Easy to extend betting sequence if losing continuously
Need to record or support tools
4. D’Alembert Strategy – Smooth Increase and Decrease
How it works:
The D’Alembert strategy is about balance and stability. After each loss, you increase your bet by one unit. After each win, you decrease your bet by one unit. Unlike Martingale, D’Alembert does not double your bet, so the risk is lower.
For example:
Start betting 10,000 VND, lose ⇒ increase to 20,000
Continue to lose ⇒ 30,000 VND, win ⇒ decrease to 20,000 VND
Advantages:
Safer than Martingale and Fibonacci
Easy to implement, suitable for cautious players
Effective if the win/loss ratio is nearly balanced
Disadvantages:
Low profit
Difficult to recover capital if the losing streak is prolonged
5. James Bond Strategy – Combining Multiple Bets
How it Works:
The James Bond strategy requires a larger bet capital, usually from 200,000 VND or more. For each round, the player divides the capital into three parts:
VND 140,000 for the high number group (19–36)
VND 50,000 for the middle number group (13–18)
VND 10,000 for the number 0 (insurance)
Results:
If the ball falls on 19–36: profit of VND 80,000
If the ball falls on 13–18: profit of VND 100,000
If the number 0: profit of VND 160,000
If the number 1–12: lose all
Advantages:
Cover many winning possibilities
Create a sense of luxury and professionalism
Disadvantages:
Requires large capital
Easy to lose everything if the ball falls on the group 1–12
