The Fibonacci Dozens system is a new addition to a range of negative progression staking plans for online roulette.

The idea is to increase your bet following a losing spin. But the difference between this system and the regular Fibonacci betting plan is that only Dozens bets are used.

Let's see if this fresh take on the Martingale is mathematically sound.

How the Fibonacci Dozens roulette system works

The original Fibonacci betting plan was named after the 13th-century Italian mathematician, Leonardo Pisano, also known as Fibonacci.

Fibonacci developed a progressive mathematical sequence that defined natural shapes like snails' shells.

The Fibonacci sequence is actually quite simple: each number is equal to the sum of the two previous numbers in the run.

For example: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, and so on.

The Fibonacci sequence, of course, lends itself to a negative progression staking plan. After a losing bet, you move on to the next number in the list to work out the following bet.

In the conventional Fibonacci roulette plan, you only place bets on the even-money bets like red, black, odd and even. In the Fibonacci Dozens plan, you stick to one of two sections: the Dozens or Columns. Either bet pays 2/1.

Playing the Fibonacci Dozens staking plan at the table

The Fibonacci Dozens plan is a little riskier than the original staking system as you are covering fewer numbers. But the payouts can be a lot bigger. Let's see how it works in practice.

For our example, we will use a standard European Roulette table, as you will find in the Betway Casino roulette lobby.

In our example, we start by betting on the first dozen, numbers 1-12. The payouts are 2/1 for each winning bet. We then decide to switch to a column bet for our second five spins.

Despite only winning three out of 10 spins, we end up in profit. The negative progression format of the Fibonacci Dozens plan means your stake increases after a losing spin. It will keep increasing until you win, then reset to the base stake.  

Advantages and disadvantages of the Fibonacci Dozens plan

The benefit of the Fibonacci system over a more traditional progression plan like the Martingale is that the bets increase more gradually. Instead of doubling after a losing spin, the stakes only go up in slight increments. And when you win, they reset to the base anyway.

The Dozens format also increases the amount you can win. The Martingale, for example, uses bets like red or black, but these only pay even money for the gambler. A winning column or dozen bet pays 2/1.

There will always be risks with any system. And if you go on a downswing, a progression system like Fibonacci Dozens can wreak havoc with your bankroll.

You also have to factor in the house edge. In European Roulette, the edge is 2.7%, which means the casino takes £2.70 for every £100 wagered. Over the long term, then, the casino will always win more from the players than vice versa.

Some negative progression staking plans can be damaging if the player goes on a long downswing. But the Fibonacci Dozens system has a flatter staking progression that is better in the long term.

As with all roulette staking plans, players should be careful when implementing the Fibonacci Dozens system. But it's fun to try for free before committing any real cash.
