The Fibonacci Sequence 101 - How To Use It In Gambling

Each number in The Fibonacci Sequence is the sum of two previous numbers, beginning with the base numbers of 0 and 1. Thus, the string begins with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, and so on (the first two numbers are 0,1, set, and the remainder is obtained by repeatedly adding the preceding numbers: 1=0=1; 2=1+1; 3 = 2 + 1; 5 = 3 + 2,…55=21+34, 89 = 34+55. As a result, the penultimate number becomes the initial term of addition with the next number when generating the string.

Bet $1 – lose (this was the default starting bet; since the first number in the string is 0, you will now raise the bet to 0+1=1, so your next bet is also $1)

Bet $1 – you lose (you now raise the bet to 1+1=2 according to the Fibonacci string)

Bet $2 – lose (include the next number in the string – 1, 1, 2; only the last two count, which means your next bet is $3)

Bet $3 – lose (continue with the sequence and add the next number – 1,1,2,3; only the last two count, so your next bet is $5)

Bet $5 – win (you were on the sequence 1,1,2,3 in the string; for your next bet, you cross off the last two numbers which means you go back to 1, 1, so your next bet is $2)

With the Fibonacci Sequence, you must choose a single betting unit with which to employ the betting system before you begin playing. You must first understand your budget and financial limits in order to determine the initial betting unit. 

Because there is a bigger potential for losses when utilizing a negative progression betting system, it is usually best to start with a smaller single betting unit, such as $ 10 or $ 20, because it is always best to start with a smaller single betting unit, such as $ 10 or $ 20. 

You should also set a limit on how much money you are willing to lose ahead of time, and stick to it. If you lose that limit, you should quit playing.

Whether you go up or down in sequence after placing a bet is determined by whether you lose or win the bet. When you lose a bet, climb in sequence; if you lose the following bet, climb in sequence again and gamble the next amount of money in the sequence. This is repeated for each loss you experience while playing. With each wager lost, increase the bet amount according to the default sequence.

Pros & Cons of The Fibonacci Sequence


When you use the Fibonacci Sequence, you get a few benefits: “Recover your losses” – no matter how many times you lose a wager, if you have a large enough bankroll, a winning bet will cover all of your recent losses. It’s simple to understand – the system is simple to observe and remember, and it only takes a few moments to think about and process before putting a wager. 

Consistent profit – because of the way this technique is set up, you will get tiny winnings on a regular basis, and the more you play, the more you will win. If you have a substantial bankroll and a smaller unit value, and the chances are close to 2.00, the method has a decent possibility of long-term success.


It has limitations, as do any betting systems: there is an initial risk that you should be aware of. When using “negative progression betting” strategies, you risk losing your entire bankroll following a string of losses (10-15 losing bets in a row, depending on which bank you have and what the unit is worth).

 The Fibonacci Sequence is primarily designed for games of chance with a 50/50 chance of winning, such as heads or tails or red/black roulette bets. If you’ve had a recent string of losing bets, it’ll become risky, if not downright frightening, to put a wager.
