Any serious roulette player knows at least a few betting systems that worked for them. There are plenty to be found, and quite a few that work to varying degrees.

One of these systems is the Fibonacci sequence based betting system. It uses the Fibonacci sequence by following its pattern and manipulating it in the event of a win or loss.

Just in case you weren't paying attention in school, the Fibonacci sequence is a series of numbers that begins with 1, 1. the next number is the sum of the previous two, meaning that if we had 1, 1, than the next number is 2. The sequence looks like this: 1, 1, 2, 3, 5, 8, 13, and so on.

The roulette is an ideal game for the Fibonacci betting system, especially if you bet on the black/red or even/odd options. The way it works is that we first select our betting unit. It shouldn't be too low, so we make a decent profit, but not too high so that we don't hit the table limit or lose our bankroll.

It's better to start out low and work your way up as you see fit.

During the game, we progress like this: If we lose, we simply move on to the next number of the series, meaning, if we lost on 3, we move on to the next number which is 5. When we win, we cross out the last 2 numbers we have. For example, if we won on 5, then we cross out 5 and 3, and our next bet is a 3 (which is 2+1).

A typical gaming sequence would look like this:

1st Bet 1 unit – lose,

2nd Bet 1 unit – lose,

3rd Bet 2 units – lose,

4th Bet 3 units – lose,

5th Bet 5 units – win, (5 and 3 are crossed out).

6th Bet 3 units – win,

Finish

Once the sequence is done, we have a profit of one betting unit and we can start the whole thing over.

This betting system does, however, have its flaws. You need to be very careful with the amount of each betting unit. Too much can be a disaster, but not enough will be painfully slow.
