Fibonacci Betting System - A Complete Overview

The Fibonacci betting system works by increasing your wagers when you lose a bet, also known as a negative progression system, according to the Fibonacci sequence.  It is more high-risk than other strategies and can be used on any online casino game that pays even money such as Roulette, Blackjack online, and online casino Craps.

A Background to the Fibonacci Betting System

fibonacci betting system nature

The Fibonacci sequence was named after the Italian mathematician Leonardo Pisano, also known as Leonardo of Pisa and Fibonacci, hence the name of the sequence. The sequence was first published in his book Liber Abaci, or in English The Book of Calculations, published as far back as 1202. However, the origins of the sequence have been said to appear in Sanskrit in Indian mathematics around 200BC. The Fibonacci sequence not only appears in mathematics very often but also in nature. Rabbits multiply in Fibonacci sequence; the patterns in tree branches and flower petals also adhere to the Fibonacci sequence, and Leonardo Da Vinci’s The Vitruvian Man is also based on the Fibonacci sequence. Now the Fibonacci sequence is used by casino players the world over in order to make winnings on their favorite games.

How the Fibonacci Betting System Works

Although it’s not the simplest betting system you will find, you don’t have to be a genius in order to learn the rules and use it when you play. It seems counterintuitive to keep betting when you have just lost money, but the idea behind it is that as you keep wagering larger amounts despite a loss, you will eventually win back your last two losing bets, not the total sum of your losses like if you were to use the Martingale betting system.

You have to memorize or write down the Fibonacci sequence – a series of numbers that you need to know when you play. You also need to know the steps to take as you move through the sequence.

Fibonacci Betting System Sequence

The sequence works in a cumulative fashion, in that each number in the sequence is the sum of the two previous numbers in the sequence. Each number in the sequence represents a betting unit. In simple numbers, this is what the sequence would look like:


When you use this sequence at one of the fantastic online casinos found in our toplist the numbers will be your betting units. This is what the sequence would look like if you have a single betting unit of $20:

$20, $20, $40, $60, $100, $160, $260, $420, $680, $1100, $1780, $2880, etc.

Fibonacci Betting System Steps

The first thing you have to do is choose an online casino from our toplist – we have many great ones to choose from. If you don’t have an account yet then sign up, and you will be eligible for some generous sign up online casino bonuses as well. Put some money into your online casino account using your online casino payment method of choice, and then pick your favorite online casino game that has even money bets.

Now you are all set up, you are ready to start using the Fibonacci betting system. Before starting to play you need to pick a singular betting unit you want to use the betting system with. In order to determine your first betting unit you need to have a good grasp of your budget and your financial limitations. It’s always best to start with a lower single betting unit such as $10 or $20 as there is greater potential for losses when you play using a negative progression betting system. You should also pre-determine the maximum amount you are willing to lose, and then be strict with yourself and stop playing if you lose that maximum amount.

Once you have placed a wager, whether you go up or down the sequence depends upon whether you lose or win your wager. You move up the sequence when you lose a bet, if you lose the next bet then you move up the sequence again and bet the next amount of money in the sequence. This continues for every single loss you incur as you play. You are always increasing the amount of the wager according to the pre-determined sequence with every single lost bet.

If you win one of the wagers, you have to move down two numbers in the sequence. If you were at 5 betting units in the sequence and you won the bet, you would move down two spots in the sequence to 2 betting units for your next wager. You do this step every single time you win a bet, regardless of where you are in the sequence. If you are still at the beginning of the sequence and you don’t have two spots in the sequence to move down, simply go back to the beginning of the Fibonacci betting sequence and start again.

Examples of the Fibonacci Betting System in Action

So you can see how this works if you were to play at an online casino, the following example shows how you would progress through the Fibonacci betting system by using a single betting unit of $5 to start with, as most online players prefer to take slightly less risks with these kinds of risky betting systems.

• Bet $5 (one unit)and lose

• Bet $5 (one unit) and lose 

• Bet $10 (two units) and lose

• Bet $15 (three units) and lose

• Bet $25 (five units) and lose

• Bet $40 (eight units) and lose

• Bet $65 (thirteen units) and lose

• Bet $105 (twenty-one units) and lose

• Bet $170 (thirty-four units) and win

• Bet $65 (thirteen units) as you won the previous bet, and you go back two steps in the sequence from 34 units to 13 units. You win again.

• Bet $40 (eight units) as you won the previous bet, you once again go two steps back in the sequence to 8 units. You lose.

• Bet $65 (thirteen units). You win again.

• Bet $40 (eight units) as you won the previous bet, you once again go two steps back in the sequence to 8 units. You win again.

• Bet $25 (five units) as you won the previous bet, you once again go two steps back in the sequence to 5 units.

This is just one example of how your betting can play out using the Fibonacci betting system as you play. This will change depending on your single betting unit and whether you win or lose. Just write down the sequence with your betting unit of choice until the maximum amount you are willing to wager, so you can always check this sequence when you are playing without getting lost.
