# Paroli Betting System: Expert Guide

Of the many betting systems out there, lauded by expert gamblers, the Paroli betting system comes across as the most user-friendly, in theory. Billed as a ‘positive’ progression betting system, the Paroli side-steps the scarier Martingale procedures to appear as a lower-risk strategy.

Still, as is often the case with popular casino game betting systems, the Paroli has its pitfalls. It may rely on a smaller capped scale and be simple in its execution, but the Paroli betting system isn’t guaranteed to work. So, here’s why you should think twice about committing to the Paroli method.

## What is the Paroli Betting System?

The Paroli betting system is a positive progression method of placing bets on evens-odds outcomes in casino gaming. Its method is simple: you bet at a flat rate until you win, and then you double the bet and double it again. After three successive wins, you stop betting and revert back to the flat rate bet to start again.

Having been around since the 16th century, the Paroli betting system is quite well-known among seasoned gamblers. Due to its simple method and attention to extending winning streaks rather than recuperating losses, it’s also become known as the ‘Anti-Martingale’ betting system.

The Paroli system comes from the Latin word ‘par,’ which means ‘one that is equal.’ The exact origins of the system are unclear, however. There is some believe that the French inventor of roulette, Blaise Pascal, is the one who came up with the system. If that’s the case, the origins would be around the 18th century.

Here’s an example of how a complete round of the Paroli betting system could run on evens-odds bets, such as on a game of baccarat:

• Bet £5, and it loses (-£5 net winnings)
• Bet £5 again, and it loses (-£10 net winnings)
• Bet £5, and it wins (-£5 net winnings)
• Double the bet to £10, and it wins (£5 net winnings)
• Double the bet to £20, and it wins (£25 net winnings)
• Stop the progression and reset to the £5 baseline flat bet

As you can see, while the Paroli betting system doesn’t seek to recover from losses, it does rely on consecutive wins to do so. The accepted practice among those who use the system is to choose a flat base bet that doesn’t exceed 5% of the bankroll. This way, in theory, there’s ample chance to complete at least one full Paroli progression.

## In Theory, When Does the Paroli Betting System Work?

The Paroli betting system works when you complete the full three-stage progression of the method more often than you lose. If you lose four times on a £5 flat bet, you’ll be £20 down. In the same session, if your other three consecutive bets result in wins, you’ll get £35 from those, putting you £15 up overall.

As with many methods, the Paroli betting system is best deployed on evens-odds options in games with smaller house edges, such as European roulette rather than American roulette. More than anything, though, the Paroli could prove to be a useful, limited risk payroll management method.

You don’t increase your base bet size, and you cap your winning streak progression after three successive wins. So, the Paroli betting system does limit your exposure if you adhere to its rules to the letter. That said, it is still being used on games with a house edge, and winning streaks still defy probability.

## When Doesn’t the Paroli Betting System Work?

The Paroli betting system doesn’t work when an ideal run of three consecutive wins doesn’t occur. Even if the probability of a two-option bet, such as the three lowest options of outside bets in roulette, was 50-50, a streak of one win, one loss, would lose money.

For example, if you start with £5 and you win, you gain £5 in profit. If the next one loses, with the bet being doubled to £10 per the Paroli betting method, you end up going -£5. Another loss, win, loss run will see you hit -£15, let alone if another loss occurs on the way. Even starting with two consecutive wins followed by a loss will set you back to -£5.

This is just assuming that it’s being deployed on the evens-odds bets on the likes of roulette and baccarat. Against longer odds, the chance of chaining wins but repeating losses becomes greater.

## Why the Paroli Betting System Doesn’t Work

The simple reason behind why the Paroli betting system doesn’t work is the fact that you’re always more likely to lose any given round of a casino game. Furthermore, the system itself mostly requires you to reach a three-win combination to succeed. It’s a method that only works in ideal situations.

As the Paroli betting system relies on three consecutive wins, the method can be broken down into sets of threes. From here, you have eight potential sequences of wins and losses, from three losses through to three wins. While progressions would continue on those that finish with a win, the majority of these put you down.

These are the only three-bet sequences in which you’ll come out on top or with a net par with the Paroli betting system:

• Loss, Win, Win
• Win, Loss, Win
• Win, Win, Win

Each of the other five put you down in terms of net winnings, and one of those above only breaks you even. The need to land three wins in a row means that the Paroli betting system doesn’t work. In terms of probability, even on the evens odds on roulette, you have:

• 48.6% chance of getting one win
• 24.3% chance of getting two consecutive wins
• 12.5% chance of getting three consecutive wins

## What to Consider When Using the Paroli Betting System

Before you can officially deploy this system, you need to know what your original stake is going to be. Being consistent about betting size is critical for getting this system to work as it was meant to. Your stake is how much you’ll risk on each bet at the beginning of the cycle.

While there isn’t a hard and fast rule about it, the unit size should be somewhere around 2-3% of your bankroll. If you start with \$5,000, your stakes should be between \$100 and \$150, depending on your percentage.

It is also imperative that, if you use this system, you get the very best odds possible. The system is built on getting close to 50/50 odds. If you are betting on odds that are too high or too low, the system won’t work properly.

## The Pros and Cons of the Paroli Betting System

If you are looking to get better with bankroll management, this is the system for you. Follow the system to a tee and you won’t be betting too big or chasing losses on a cold streak.

It also happens to be perhaps the easiest system out there to follow. Even if you are somewhat new to gambling, you can figure out the Paroli system easily.

Using this system is great for learning the ropes, growing consistently overtime, and learning patience. While you might not achieve a big win, you also won’t go broke quickly which is the more likely outcome without a system. Even in the face of a cold streak, it is minimal damage done to your bankroll.

On the downside, you have to hit three bets in a row for it to really work. Even at 50/50 odds, your chances of losing are just as strong as they are winning. The system doesn’t improve your odds of being a long-term winner and there is no way to know how long it could take to rip off three straight winning bets.

In the end, the Paroli system is for the kind of player who wants to keep risk to a minimum. Unfortunately for the player, risk is always part of the game whether it be a casino game or sports betting. But putting yourself in the best possible position to win is as good as one could hope to achieve.

## What’s better than the Paroli Betting System?

The best way to play casino games online is to set a hard limit for your payroll and put all of your winnings to one side. The Paroli betting system is inherently flawed if you follow it for any reason other than a way to structure your round-to-round betting.

Still, the best way to bet is to place your chips in whatever way you will enjoy the game the most. If that means randomly putting chips across the inside bets of roulette or betting the same amount for each hand of baccarat, that’s your best way to play.

It’s clear to see that the Paroli betting system doesn’t work and that you need a probability-defying run of luck for it just to pay off once. So, stick to your own preferences and limits instead.
