Roulette is probably the most famous casino game. That’s because they are always very prominent and often appear in movies as well. It is also an easy game to participate in.

Despite the fact that it is a game of chance and the casino always has a house edge, there is something you can do to increase your chances. Play with the right strategy. There are several. In this article we’ll cover the Fibonacci strategy.

The basis of the Fibonacci system

The Fibonacci strategy has a mathematical basis, but if you play with it for a while anyone can master it. The strategy starts with 0 and 1, the 1 representing your basic bet. Then the next digit is constantly the sum of the two previous digits. So in this case this is; 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 and on and on. This is not really difficult. But then how does this strategy make your chances of winning grow?

Fibonacci SystemApplying the Fibonacci System to single chances

Influence of Fibonacci

Fibonacci at roulette is applicable to the single odds. Many people use the Fibonacci system, for example in Holland Casino. Every time you make a bet on one of the possible 50/50 options on the roulette table and you lose, you have to increase your bet in the next round according to the above series.

Single Odds

The single odds on a roulette table are plentiful. For example, you can choose red and black as colors, with those two having almost a 50% chance of falling each. Of course, the number 0 also plays a part and so, in practice, the probability of red or black is 48.6% to 48.6%, the result of the equation 18 numbers / 37 numbers.

The same applies to even/even and 1 to 18 and 19 to 36. In roulette, the number 0 is a neutral number. The number 0 does not count as an even number and does not count towards the higher/lower odds.

Suppose you start with a bet of 5 euros, which is a standard minimum bet on roulette tables in the casino, then the Fibonacci sequence could look like this:

  • First bet: 5 euros on red (lost)
  • Second bet: 5 euros on red (lost)
  • Third bet: 10 euros on red (The sum of 5+5, lost)
  • Fourth bet: 15 euros on red (lost)
  • Fifth bet: 25 euros on red (lost)
  • Sixth bet: 40 euros on red (won)

So what do you have left over underneath the line? On the sixth bet you win and that means you get your bet back doubled. So you get a total of 80 euros back. This 80 Euros will be compared to all six bets you have made up to that point. In the above example, this is 5+5+10+15+25+40 = 100 euros.

In the Fibonacci system, when you win, you always go back two steps in your sequence, so your next bet will then be 15 euros (fourth bet). It ensures that when you win you always earn back the previous two bets.

The example we give is also a negative one, because you will have lost five times and already have incurred a small loss. It can also be positive, as in the example below;

  • First bet: 5 euros on red (lost)
  • Second bet: 5 euros on red (lost)
  • Third bet: 10 euros on red (won)

The Fibonacci tactic assumes that you will win within three or four bets. Not a crazy thought at single odds. The Fibonacci strategy is especially suitable for people who want to gamble with less risk, but your bottom line will often be slightly lower as a result.

    Who was Fibonacci?

    FibonacciFibonacci is considered by many to be one of the greatest mathematicians in Europe during the Middle Ages. However, his real name was Leonardo Pisano. He was born in the year 1170 in the Italian city of Pisa. For his education he went to North Africa and during his studies he learned to calculate with the number 0. This number originally came from India and according to Leonardo Pisano could be efficiently calculated with this number. It was not until 1202 that the current number system we know was introduced to Europe. After his death, Leonardo Pisano was nicknamed Fibonacci.
