If you are a casino fan who loves taking risks, roulette is the perfect game for you. This classic table game combines a touch of glamour with plenty of excitement. One of its most distinctive features is the wide range of betting options it offers. For years, roulette tables have attracted the attention of millions of players who have eagerly tried to overcome the game’s house edge. That’s why roulette betting systems were created.

Sports fans are well acquainted with the term “parlay” – a type of sports wager that involves two or more bets. The Parlay isn’t just a sports bet; it’s also a popular roulette strategy. The origin of the Parlay betting system can be traced back to the 16th century. The strategy can be applied to many of the casino’s most popular games, including roulette, blackjack, craps, and baccarat.


How the Parlay Roulette System Works?

The Parlay betting system belongs to the positive progression category of betting strategies. Many roulette fans rely on it because it is considered safe and easy to learn. If you decide to follow the Parlay betting strategy, you must increase the size of your bet after every win by adding your profits to your initial wager. Whenever you lose, you have to revert your stake to its original size and keep it there until you win again.

The difference between the Parlay strategy and other roulette techniques is that players use their winnings instead of their own funds to place bets. Another popular name for the Parlay betting strategy is “Let It Ride.” Below is an example that illustrates how the system works in practice:

Bet Number Bet Size Outcome Net Profits
1 10 Win 10
2 20 Win 30
3 40 Win 70
4 80 Win 150
5 160 Loss -10

Had we stopped playing after the fourth spin, we would have locked in a net profit of $150 on the $10 we invested at the start. However, we chose to stay for another spin, our luck turned, and we lost all our winnings.

Another key takeaway is that our net loss equals the size of our original stake – $10. That is why it is essential to set a profit target; otherwise, you may lose everything and have to start the progression all over again.

To sum up, players who want to use the Parlay strategy have to:

  • Determine a base unit
  • Set a winning goal
  • Add winnings to the size of the original bet after a win
  • Wager the base stake following a loss

Setting Initial Bet Size

Roulette enthusiasts looking to adopt the Parlay strategy must set an initial bet size. To determine the exact amount, first decide how much you can afford to spend on roulette during a single session. Experts advise that the base bet should be no more than 5% of your bankroll. Alternatively, you can use the minimum table limit as the base bet to minimize the chances of hitting the maximum table limit.


The Target Profit

As already noted, it is crucial to set a target profit; otherwise, you are likely to give back your winnings. Once you reach your goal, you should collect your profit and start the progression again. Keep in mind that the Parlay betting system is not profitable over the long run, so if you rely on it too long, the house edge will eventually erode your bankroll. For example, the Paroli betting strategy instructs players to collect their winnings after three consecutive wins.


Modifications to the Parlay Betting System

Recreational roulette players may tweak the Parlay betting system to make it even safer. One option is to use only a portion of your profits to increase the size of the original wager. For instance, if your initial bet is $10 and you win an additional $10, your next wager could be $15 (your initial stake plus half of your net winnings).



How Efficient is the Parlay Betting System?

Undoubtedly, the Parlay roulette system can help you generate some profit in the short term. However, no betting strategy, including the Parlay, can overcome the house edge. Roulette is a game based on pure chance, meaning that the outcome of every spin is random.

Some novice roulette players believe that there is a relationship between past results and future outcomes. This erroneous belief is known as the gambler’s fallacy. In reality, each spin is independent of any other, and the probability of winning a given bet does not change based on previous outcomes.

Roulette betting strategies do not increase the odds of winning; therefore, they cannot guarantee long-term success. Even though the Parlay strategy sounds logical and safe, it is not foolproof. In the lines below, you can learn more about its advantages and disadvantages.

Even inexperienced roulette enthusiasts will grasp the idea behind the Parlay betting system in no time. The simpler a betting strategy is, the easier it is to apply. Moreover, the Parlay betting strategy is not steep. Players do not have to dramatically increase the size of their bets, which means the chances of reaching the maximum table limits are slim.

Unlike some betting strategies, such as the Martingale, the Parlay system is suitable for roulette fans with any bankroll size. Furthermore, this betting system is regarded as one of the safest because players use their winnings to increase their bets.

Most roulette betting strategies are geared toward even-money bets. However, if you place the same bets every time, you will quickly get bored and leave the roulette table. Fortunately, the Parlay roulette system can be applied to all inside and outside roulette bets.

Compared to other betting strategies, the Parlay system has only a few drawbacks. The first is that it cannot be used effectively in the long term. Additionally, the Parlay betting strategy relies on a sequence of lucky events. If you generate consecutive losses over a period of time, you risk wiping out your bankroll. If you are on a hot streak, you must end the progression whenever you reach the target profit.
