We summarize the Fibonacci betting method in our article, with a video and roulette example. The method can be used in many gambling games and is less aggressive than the Martingale method, but requires more capital than the D’Alembert.
As its name suggests, the method is based on the Fibonacci sequence familiar from high school.
As a reminder, you can see the first 16 digits of this sequence below.
We will use this to determine the size of the bet.
Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987.
Similar to the Martingale or D’Alembert methods, here too we will increase the bet after a losing round and decrease it after a winning round.
At the beginning of the game, we need to determine a starting bet, which we will use as a unit bet in wagers. Our current bet will be the product of the unit bet and one of the Fibonacci numbers.
The first bet multiplier we will use is the second term of the Fibonacci sequence, which is 1. If we lose in a round, we move forward one step in the sequence.
If we win, on the other hand, we move back two steps in the sequence.
Now, let's illustrate with an example.
Suppose we are playing roulette and consistently betting on the color red.
We came to play with $5,000 and determine the unit bet to be 1%, which is $50.
In the table below, you can see the details of 10 example rounds.
In the first round, we place the starting bet of $50.
In case of a loss, we increase the bet by one according to the Fibonacci number multipliers.
If we win, we decrease our current bet by two in the sequence.
| Round | Bet* | Outcome | Balance at the end of the round |
|---|---|---|---|
| 0 | – | – | $5,000 |
| 1 | $50 (1*50) | Lose | $4,950 |
| 2 | $100 (2*50) | Lose | $4,850 |
| 3 | $150 (3*50) | Lose | $4,700 |
| 4 | $250 (5*50) | Lose | $4,450 |
| 5 | $400 (8*50) | Win | $4,850 |
| 6 | $150 (3*50) | Win | $5,000 |
| 7 | $50 (1*50) | Win | $5,050 |
| 8 | $50 (1*50) | Win | $5,100 |
| 9 | $50 (1*50) | Lose | $5,050 |
| 10 | $50 (1*50) | Lose | $5,000 |
Number of winning rounds: 4
Number of losing rounds: 6
Profit with the Fibonacci method: $0 (0 unit)
Loss with constant betting: $100 (2 units)
Fibonacci numbers:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987
The example we used demonstrates an unfortunate gameplay. Out of the ten bets, we won four and lost six. Despite this, our final balance matches the starting balance. Let's assume that we play the same rounds, but instead of using the Fibonacci method, we always place a fixed bet of $50. In this case, our balance would be negative, with a loss of $100, which equates to 2 units.
As the example illustrates, this method can be useful, similar to the Martingale, in emerging from slightly unfortunate gameplays with a neutral or positive balance. However, if we experience a moderately or extremely unlucky gameplay, this method accelerates the depletion of our gambling funds. And as experienced players know, sooner or later, everyone encounters a streak of bad luck.
