1️⃣How does the Fibonacci strategy work?

Before the game, you set a specific sequence according to the Fibonacci sequence. Most often, it starts at £1. If you lose, the bet moves one number higher in the sequence, and each win reduces the bet by two numbers closer to zero.

2️⃣Is the Fibonacci strategy worth it?

If you want to learn how to work with your bankroll, you want to set a clear sequence that you want to follow and you don’t mind a higher risk, you can definitely try the Fibonacci strategy to diversify your game. But definitely don’t count on a high or even guaranteed profit. No strategy can guarantee you that..

3️⃣Who is the strategy suitable for?

Of course, any player can try it. The strategy is very simple to understand and can be used well to learn the rules of roulette. However, we do not recommend it to players who want to play roulette for higher profits.

Roulette

Ever since roulette was first played, people have been trying to find strategies to help them beat it. One very popular method is the Fibonacci strategy, named after the legendary mathematician. In this article, we will introduce it in detail and show how it can work in practice.

Principle of the strategy

The Fibonacci strategy is not at all difficult to understand. However, in order to be able to explain its principle itself, we must first familiarize ourselves with the Fibonacci sequence on which the strategy works.

It is an infinite sequence of natural numbers starting at 0, where each number is the sum of the two previous numbers
0 – 1 – 1 – 2 – 3 – 5 – 8 – 13 – 21 – 34 – 55 – 89…
When you lose, you increase your bet by one number higher in the sequence. When you win, you go back two numbers back to zero.

The goal of the strategy is to maximize the ratio of wins and losses, where any win is always greater than any loss in the next round.

Fibonacci Strategy in Practice

Of course, it is best to explain the course of this strategy using a specific example. You can find it on the following lines, including a table of the entire course of our sample game.

Preparation:

Bet: even numbers
Sequence: 1 – 1 – 2 – 3 – 5 – 8 – 13
Bankroll: £100
Number of rounds: until the sequence is exceeded or after returning to the original bet

Example No. 1:

Round	Sequence	Bet	Round result	Bet result	Profit
1.	1	£1	Black 15 = Loss	– £1	– £1
2.	1 – 1	£1	Red 27 =Loss	– £1	– £2
3.	1 – 1 – 2	£2	Green 0 = Loss	– £2	– £4
4.	1 – 1 – 2 – 3	£3	Red 14 = Win	+ £6	– £1
5.	1 – 1	£2	Red 7 = Loss	– £2	– £3
6.	1 – 1 – 2	£3	Black 9 = Loss	– £3	– £6
7.	1 – 1 – 2 – 3	£5	Red 16 =Win	+ £10	– £1
8.	1 – 1	£2	Black 30 = Win	+ £4	£1

We didn’t do very well in our demo game at first. Thanks to a lucky streak, we eventually recovered all our losses and managed to make a profit of 1

Example 2:

In the second example, we will show what a negative profit could look like:

Round	Sequence	Bet	Round result	Bet result	Profit
1.	1	£1	Black 35 = Loss	– £1	–£1
2.	1 – 1	£1	Red 21 = Loss	– £1	– £2
3.	1 – 1 – 2	£3	Red 12 = Win	+ £6	£1
4.	1	£1	Red 7 = Loss	– £1	£0
5.	1 – 1	£1	Green 0 = Loss	– £1	– £1
6.	1 – 1 – 2	£3	Black 13 = Loss	– £3	– £4
7.	1 – 1 – 2 – 3	£5	Red 19 = Loss	– £5	– £9
8.	1 – 1 – 2 – 3 – 5	£8	Black 11 = Loss	– £8	– £17
9.	1 – 1 – 2 – 3 – 5 – 8	£13	Black 29 = Loss	– £13	– £30
10.	1 – 1 – 2 – 3 – 5 – 8 – 13	£21	Red 25 = Loss	– £21	– £51

This example shows how quickly you can get to high stakes after a series of losses. It is clear that no strategy can simply guarantee 100% profit.

Using any roulette strategy requires discipline and a clear definition of the limits within which we will operate in the game. Since bets in the later stages of the Fibonacci sequence increase at a dizzying pace, it is necessary to know when to stop.

Advantages and disadvantages of the strategy

Winnings offset losses - as the bet increases after each loss. The subsequent win will cover the losses
Easy to understand - very easy to apply and with a sufficient bankroll can continue indefinitely

Risk of big losses - if a losing streak comes, you can quickly get into a big deficit and a call is not guaranteed
Casino limits - in later higher stakes, casino limits may limit you and you may leave empty-handed

Is it worth using the Fibonacci strategy?

If you want to learn how to work with your bankroll, can set a clear sequence that you want to follow and do not mind a higher risk, you can safely use the Fibonacci strategy for your game. It is very good at balancing the ratio between wins and losses.

However, like all strategies, it cannot guarantee any long-term profit (the casino will always win thanks to the high house edge of roulette) and with longer bonuses without a win, it can really shake up your bankroll. With longer winning streaks, it will not bring you anything too fundamental, because you are constantly reducing your bets. From our point of view, it can be tried, but there are also more interesting strategies.

However, if you are still afraid of losing, you can try the strategy on free online roulette, where you do not play for real money and do not risk anything.

History of the strategy

Fibonacci Strategy

The Fibonacci Strategy is named after one of the most talented mathematicians of the Middle Ages, Leonardo Bonacci, or Leonardo of Pisa. Fibonacci is his nickname, which he received only in the 19th century from the historian Guillaume Libri.

It is not entirely known when his strategy began to be used for the game of roulette. However, unlike some other strategies, we can say with a clear conscience that he himself never got around to playing roulette as such. He died more than 400 years before it was first spun.

The strategy is applied not only in roulette and other gambling games with a 1 to 1 payout ratio, but also in business sectors. Its goal is primarily to optimize losses in relation to wins and is generally considered a rather conservative approach when followed.
