# Fibonacci Roulette System

Leonardo de Pisa was a mathematician born in 1170 AD who introduced a number sequence now known as the Fibonacci. Although his work was known to Indian mathematicians as early as the 6th century, his book Liber Abaci, posed and solved a problem involving the growth of a population of rabbits by adding the parents (1+1) and then continuing with a calculation that included the sum of the previous two numbers in a sequence. His work, while noteworthy at the time, is now most often linked to the game of roulette after game aficionados applied the sequence to wagers and had some moderate success.

Like the d’Alembert roulette system, the Fibonacci calls for a sequence of wagers to be played for maximum success. The Fibonacci sequence is: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233. When followed, a winning number will return the two previous losses.

## How to Play the Fibonacci System

The Fibonacci is usually played on even-money roulette bets (and European rules that offer En Prison) such as Red/Black and Odd/Even where the player makes a single unit wager and awaits the outcome. The unit may be any specific amount of their choosing, such as €5. If they win, they continue with a single unit until a loss. After a loss, the next wager is the sum of the previous two losses, so the next bet is also 1, but a third loss would call for a wager of 2, then 3, then 5 etc. When a new win takes place, the two previous wagers are dropped and the betting starts up with the number three back from the high point.

Unlike the Martingale, the Fibonacci is not designed to recoup all losses with a single win. Instead, the allure is that the risk is lower than the Martingale and the player can still get ahead with less wins than losses. An example is a 6-loss streak where the player has wagered 1+1+2+3+5+8+13 and finally wins with the wager of 13. This wipes out the 8 and 5 bets, leaving a loss of just 7 units and the next wager is 3 units.

However, some players tweak the betting just a tad, and instead of reversing back three spaces (13, 8, 5) and wagering 3 units, they only go back two spaces and wager 5 units. This adds more risk, but allows the player to make a profit after just a few wins!
