Ever since roulette first appeared on the floors of gambling houses, players have been trying to devise methods that would allow them to beat the Devil’s Wheel. This never-ending quest to prevail over the house has led to the emergence of numerous roulette systems, most of which are based on either negative or positive betting progressions.

Progressive systems have proved to be extremely popular among roulette players, a fact that can be attributed to two main reasons. First, most of them rely on a relatively simple set of rules, enabling players to incorporate them into their gaming sessions without much difficulty.

Second, progressive systems give gamblers the deceptive impression that they work when they actually don’t, or at least not over the long term. You may generate some profits occasionally, but the fact of the matter is that such systems have zero influence on your odds of winning in the long run.

In light of this, we will delve deeper into the most popular progressive roulette systems, explaining how they work and why they inevitably prove ineffective. By the time you finish reading, you will have a better understanding of progressive betting, allowing you to decide for yourself whether you should use this method.

A Few Words on the Concept of the Gambler's Fallacy

1The Concept

Before we proceed with further explanations of progressive systems, we would like to say a few words about a concept known as the Gambler’s Fallacy. Also called the Fallacy of the Maturity of Chances, it stems from a cognitive bias in which a person mistakenly believes that if a random event occurs more frequently during a short period, it will occur less frequently in the future.

In roulette (a random game based on independent events), this means a player may feel the ball is due to land on black because red has appeared several times in a row. The most notorious instance in which this inference proved wrong occurred in August 1913 at the Monte Carlo Casino, which is why the bias is sometimes referred to as the Monte Carlo Fallacy.

Millions were lost that night when the ball landed on black 26 times in a row – an extremely rare occurrence (1 in 66.6 million). Gamblers stubbornly continued to bet on red, assuming it was “due” because the long sequence of black outcomes had created an imbalance in the wheel.

2Streaks

Interestingly, the Gambler’s Fallacy can also manifest in reverse. It occurs when a player assumes that black is more likely on the next spin after the ball has landed in black pockets several times in a row. This reasoning stems from gamblers’ belief in streaks.

However, this line of thinking is equally flawed, especially when one is playing on a balanced wheel that produces completely random results and shows no bias toward specific numbers or sections. In such a “fair” game of roulette, each outcome is entirely independent of the previous ones.

3Patterns

Moreover, streaks have no impact on future spins. Roulette is based on independent trials; therefore, red and black are always equally probable (each has 18 winning pockets against 19 losing ones on a wheel with one zero). Humans are inclined to look for short-term patterns, but these cannot be trusted, even though our brains try hard to convince us otherwise.

Many roulette players fall prey to the Gambler’s Fallacy because they believe they have identified a short-term pattern that will help them beat the game. They use betting progressions because they do not think a streak can last long enough to harm their chances. Unfortunately, this belief often leads to disastrous financial results.

Key Principles of Positive and Negative Roulette Progressions

The two most common types of roulette systems are based either on positive or on negative betting progressions. Both types of systems rely on previous outcomes to determine the amount the player bets on subsequent spins. The exact bet sizing depends on the type of system one uses and whether it is based on a positive or a negative progression.

Positive progression systems like the Paroli require the player to increase their stake after a winning round and reduce it after a loss occurs. These are less damaging than negative progression systems.

Negative progression systems work in the opposite manner as they require you to increase your wager after a losing spin and decrease it after you register a win. Exactly how you adjust the wagers after losing depends on the particular progression you use.

Their primary purpose is to help gamblers win more and capitalize on winning streaks. A positive progressive system can earn you decent profits during a long favorable streak and is less likely to destroy your bankroll during a losing one. Despite this, it has no impact on your overall odds of winning or losing a bet.

Some negative systems like the Fibonacci rely on extremely steep progressions. If you are playing on a shoestring budget, they can wipe out your session bankroll in several consecutive losses only.

The main premise behind negative progressions is they help the player recover their losses during a long bad streak. Here you are not trying to boost your profits but are aiming at diminishing your losses instead. Let's now delve into some of the most popular negative progression systems for roulette, starting with the infamous Martingale.

Where Progressive Roulette Systems Fall Flat

1No impact on the odds

Progressive roulette systems fall flat for several reasons, beginning with the fact that bet-size adjustments are based on previous results. These systems have no effect on a player’s odds of winning, which stay the same for every spin of the wheel. Each number has the same chance of hitting in any round as every other number. How many times you have won or lost in previous rounds is irrelevant to the wheel.

2The House Edge

Furthermore, using a progressive system does nothing to reduce the house edge. Every bet you place, no matter how big or small, is subject to the same casino advantage (2.70% in European roulette and 5.26% in American roulette). No matter how cleverly you size your wagers, your profits will never be enough to overcome that edge.

3Computer Simulations

Most systems built on this principle may perform well in the short term but prove useless over time. Experts have tested popular betting progressions like those described above using computer simulations, and the outcome has always been the same over millions of trials: the ratio of money lost to money wagered matches that of flat betting because of the house edge.

Some proponents of betting progressions argue that no one can play millions of rounds in a real casino. They swear by their systems, claiming they fare poorly in computer simulations but would work flawlessly in “real life.”

Unfortunately, this excuse carries no mathematical weight. Simulations run millions of rounds simply to demonstrate a system’s flaws. If the strategy performs poorly on a computer, there is no reason to expect it to produce positive results in an actual casino environment.

4Bad run

There are two additional problems with system play, especially when you use a negative progression to size your bets. What happens if you are under-bankrolled or are seated at a table with a low maximum limit?

In the first scenario, a devastating losing streak (not uncommon in roulette) can completely wipe out your bankroll. You will be unable to continue the progression and will fail to recoup your heavy losses. The same issue arises with the table maximum. When you reach it during a bad run, you cannot offset your prior losses, even if you have more money to keep increasing your bets according to the negative system.
