## "One step forward, two steps back".

The strategy is based on the use of the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34 ...), where each successive number is equal to the sum of the two preceding ones.

The game bank is divided into parts, proportional to the Fibonacci numbers. For example, a $1,430 game pot will be divided as follows:

- Step 1: $10.
- Step 2: $10
- Step 3: $20
- Step 4: $30
- Step 5: $50
- Step 6: $80
- Step 7: $130
- Step 8: $210
- Step 9: $340
- 10 step: $550

In case the 1st bet loses $10, the 2nd bet will also be $10 (Step 2). If the 2nd bet also loses, then proceed to step 3, where the size of the bet is $20. The general rule: in case of losing we increase the bet by "1 step forward". In our case, a maximum of 9 losses in a row is allowed.

In case of winning we decrease bets by "2 steps back". For example, if at step 6 the winning bid is $80, we pass to step #4, i.e. the size of the next bet will be $30.

## Scientific studies

The Fibonacci strategy is of interest to bettors and mathematicians alike. In 2007, scientists Osborne and Archontakis published an article in the Journal of Sports Economics about a study of the Fibonacci sequence in betting.

The scientists looked at soccer parimatch online betting on draws with the bet size increasing in proportion to the Fibonacci numbers. As they summarized in the publication, the strategy is profitable if the odds are at least 2.618.

## How to Use the Fibonacci Strategy

There are two difficulties in using the strategy:

- 2.618 is a high odds. The outcomes with such odds are difficult to predict, which means a protracted losing streak is possible.
- Bets need to be placed one at a time, whereas in many soccer championships, tour matches are played simultaneously.
