# Roulette Strategy P.2

The d’Alembert system is often referred to as a safer version of the legendary Martingale strategy. It is perfect for players who prefer not to take risks, and it will also help beginners who are learning the basics of online roulette to avoid big losses.

## Origin of d’Alembert’s strategy

The d’Alembert system is the brainchild of the French mathematician Jean Leron d’Alembert. It was first used at about the same time that the roulette itself appeared in its modern form – in the second half of the 18th century.

In addition to inventing the strategy that is widely used today in the world of online casinos, Jean d’Alembert also played an important role in the creation of the legendary French reference book of the Enlightenment, the Encyclopedia of Sciences, Arts and Crafts, editing the scientific and mathematical sections of this book.

D’Alembert was a progressive thinker who held liberal views for his time and spoke out against religious prejudices. At the same time, mathematics has always been a matter of life – today, thousands of casino fans around the world know the name of D’Alembert primarily thanks to the financial strategy he developed.

## How the d’Alembert strategy works

The basic idea behind the D’Alembert strategy is simple: if you lose, add €1 to your bet, if you win, subtract €1. When the bet amount reaches 0 €, you will win.

## Key Findings

Before trying the d’Alembert system in practice, remember the following key points:

D’Alembert’s strategy only works with even money bets: red/black, 1-18/19-36, even/odd.

Start with a small bet. This will help avoid bankruptcy at the beginning of the game.

When you lose, increase your bet by 1 €, and when you win, decrease by 1 €.

If the bet amount has reached 0 € — congratulations, you are in profit! Luck is on your side, which means you can try your hand.

### Fibonacci strategy in roulette

Another progressive strategy that is used exclusively in equal money bets: red/black, even/odd, 1-18/19-36. The Fibonacci strategy is often referred to as a simplified version of the Martingale and is great for beginners.

Unlike most other strategies, the origin of the Fibonacci system, as a derivative of the Fibonacci number sequence, predates the invention of the game itself and dates back to the time of Leonardo Fibonacci (1170-1250) – about 800 years ago!

You must have heard of the Fibonacci numbers, which are a sequence where each number is the sum of the two numbers that preceded it:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55…

How can this sequence be applied in online roulette? We tell below.

### How does the Fibonacci strategy work?

Use the above sequence as a template. Choose from it any number you want to start with – this is your initial bet.

You can always pick a bigger number, but it’s safer to start with a smaller bet. This way you will avoid a significant increase in the amount of the bet if luck is not on your side.

If your original bet wins, repeat it or move down to the lower number in the sequence. If the bet has lost, increase it by moving to the next highest number in the sequence.

Let’s say you start with a bet of 3€. If you win, great, bet 3 € again or go to the lower bet from the sequence (2 €). And if the bet is lost, raise it: bet 5 € and then 8 € if you lose again.

As soon as the bet wins, go back in sequence two numbers back from the winning bet. For example, if you win with a bet of 8 €, go back to 3 €. And keep doing this until you return to your initial bet – by this moment you will already be in the black.

### Key Findings

Once again, briefly about what you need to remember before putting the Fibonacci strategy into practice:

The Fibonacci strategy only works with equal money bets.

It is better to start with a small number and gradually increase it than to choose a large amount and then bet even bigger if you fail.

If the original bet wins, you can play again or cash out your modest profit. Remember: you should not chase losses if you have a black streak. This can lead to even bigger losses in the long run.

### Roulette the Paroli system

Another variation of the Martingale strategy – the Paroli system – is ideal for beginners who are afraid of big losses. It’s essentially an inverted version of Martingale: you have to double your bet every time you win.

### How does the password system work?

The Paroli system is based on the Martingale strategy and probably originated around the same time. It has been widely used in online casinos since the 1990s and is popular among players who like to bet small and win big.

Unlike the Martingale strategy, in the Parola system, bets are doubled after a win, and not after a loss. The idea is that after a series of consecutive wins (usually three or more), the player will make a profit that will allow him to leave the table with his head held high and his wallet intact.

An example of such a strategy can be seen in the table below. Please note that after each loss, you need to return to the original bet amount. Also remember that the Paroli system only works with even money bets: red/black, 1-18/19-36, even/odd.

### Key Findings

Before trying the Password system in practice, remember the following key points:

The Paroli system only works with equal money bets.

The essence of the system is doubling the winning bets a certain number of times (usually three or more).

This is the best roulette strategy for players who like to play with casino money and not their own.

If you’re unlucky at the table, don’t chase your losses. Ultimately, this can lead to even more losses.
