The Paroli Roulette Strategy

One of the most popular betting strategies used throughout casinos today is the infamous Paroli system in roulette. Derived from the Latin word, par – meaning ‘one that is equal’, the system has been successfully used by gamblers since the 1600s. The Paroli roulette strategy is the complete opposite of the heralded Martingale system. Although, instead of trying to recover your losses, the Paroli betting system focuses on capitalising on your wins and playing with house money. Put simply, when you win, double your bet, and if you lose, start again.

The Paroli betting system can be applied to more than just roulette games. It can be utilised in any game featuring even odds such as baccarat, craps and with a few modifications, blackjack. Whilst there is no doubting its popularity and simplicity, there are a few shortcomings to the system as well. Let’s find out what they are.

The Pros and Cons of Using the Paroli System in Roulette

Many Paroli supporters argue that the system is great because it gives players the opportunity to bet big with house money and minimises your losses during losing streaks. While this is true, the Paroli roulette strategy does not have any impact on the inherent house edge, and it has its own unique flaws.

How on Earth Does the Paroli Betting System Work?

The Paroli roulette strategy is only meant to be used on even-money wagers such as betting on low (1-18) or high (19-36), odd or even or most commonly, red or black numbers. The primary objective of the Paroli system is to play until you achieve three wins consecutively. It starts by deciding what your minimum bet will be. This is very important as you may have to sustain a series of losses, so make sure it is relative to your personal bankroll. For this example, our minimum bet will be £1 and we will be betting on the probability that the ball lands on red. If we lose after the first spin, we will place the same £1 bet again. We will continue to do this until we win. Following a win, we will double our bet to £2. If this bet loses we will return to betting £1. However, if the £2 bet wins, we will double our next bet to £4. If we were to win all three of these bets in row, we would finish with a total profit of £7. Once you have achieved this, you should retrieve your winnings and start betting again with your minimum bet, in this case, £1. For any three consecutive bets, there are only eight potential outcomes. Check out the table below to gain a better understanding of how the Paroli system works.

Outcomes of the Paroli Roulette System (with a £1 Bet)
First Bet Second Bet Third Bet Net Profit/Loss
£1 loss £1 loss £1 loss – £3
£1 loss £1 loss £1 win – £1
£1 loss £1 win £2 loss – £2
£1 loss £1 win £2 win + £2
£1 win £2 loss £1 loss – £2
£1 win £2 loss £1 win £0
£1 win £2 win £4 loss – £1
£1 win £2 win £4 win + £7

Working Out Your Odds

The pivotal question underlining the Paroli roulette strategy is working out how many progressions you should play before retrieving your winnings and starting over again with your initial bet. Whilst the recommended number of wins to stop by is three, players who enjoy taking more risks or have a higher bankroll may prefer to play more. If you choose this strategy, your pay out will increase dramatically, however, your probability of winning decreases as well. Let’s have a look at the mathematics. The chances of winning on red or black in European roulette is 48.6%. Remember, it is never an exact even bet because of the green zero field in the roulette wheel, also referred to as the house edge. Whilst winning three consecutive games in a row could stand to win you eight times your initial bet, there is only an 11.5% chance of that actually happening. The probability of winning five consecutive times plummets to 2.7%. Familiarise yourself with the below table to give yourself a better understanding of how the risk-reward elements of a Paroli system roulette game unfold.

Your Odds of Winning with Paroli (Starting with a 1-Chip Bet)
No. of Progressions Chance of Winning No. of Chips Won
1 48,60% 2
2 23,60% 4
3 11,50% 8
4 5,60% 16
5 2,70% 32
6 1,30% 64
7 0,60% 128

Other Betting Systems

Now you’ve had time to digest the Paroli system, lets take a look at some of the other niche systems on the menu today. The Garcia system relies on the bank not winning two times in a row. Playing with nine units in total, the player bets one third (three units). If the bet is lost, the player bets the remaining six units. Provided the player doesn’t encounter two consecutive losses, they can increase the initial capital of nine units up to and above 200 units. The Garcia strategy is strong as the player won’t lose more than nine units however, the Paroli betting system is a lot more resistant to losing streaks.

The Oscar’s Grind system believes that there are both periods of winning and losing streaks. In short, if you lose a bet, you bet the same amount, and when you win, you raise the bet by one unit. This strategy can withstand many bad runs, however, the Paroli system gives a lot more opportunity for bigger wins.

Using this Strategy in a Casino

When you’ve spent enough time practising at home and are starting to get a feel for how the Paroli system works, you will be ready to use it in your favourite roulette casino. The first thing you should do is notify the croupier at your table of your Paroli approach and how many progressions you want to do. This means the croupier won’t accidentally remove your winnings from the table until all of your progressions are complete. Never forget the golden rules.
