Roulette Strategies

What Are Roulette Strategies?

The objective of a roulette strategy is clear. By betting money according to a certain plan and an individual approach, the aim is to try to make a long-term profit from the game of chance. Other games like poker require tactics and skill, making it possible to increase the chances of winning significantly with clever moves and your own thinking. At least this is true if you are facing off against other players and not against the bank. However, this definitely does not work if playing roulette. 

On a fair roulette wheel, each spin is independent and its outcome cannot be predicted from previous results. Staking systems change the amounts bet as results arrive, but they do not change the wheel’s probabilities. This guide explains several common progressions and the bankroll and table-limit risks that can stop them.

Martingale

Probably the best-known roulette strategy is the so-called Martingale strategy. It mainly attracts inexperienced players because it follows a very simple principle: you only bet on simple chances and every time you lose you double your stake for the next round. This way, a win evens out all previously lost bets, so that all losses are recovered. Once a bet is successful, you take your money off the table and go back to your initial bet size.

In addition, the chances of winning with simple chances are almost 50 to 50, which leads players to believe that a win cannot stay away for too long. Sounds very tempting, doesn't it? There are numerous other variants of the Martingale, which we will not go into detail about here. But fundamentally all of them have the same idea in common.

Example of a Martingale game: choose a starting stake of €1 on an even-money bet. After losses, the next stakes would be €2, €4 and €8. If a winning bet can be placed before the budget or table limit stops the progression, it recovers the preceding full-stake losses and produces €1 in net profit. Reset to €1 after that win. This arithmetic does not guarantee that the required winning bet will be reached.

The Reverse Martingale

Reverse Martingale increases the next stake after a win and reduces it after a loss. It can produce short winning streaks, but those streaks do not predict the next roulette result. A loss can erase accumulated gains, and bankroll and table limits still apply. Changing the stake does not remove the house edge.

Paroli

Paroli, also called Reverse Martingale, increases the stake after a win and returns to the starting stake after a loss or a chosen winning-streak limit. For example, a player might double after each win and reset after three consecutive wins. This changes the pattern of stakes but does not improve the odds of an even-money roulette bet or remove the house edge.

Example of the Paroli strategy: start with €1 on an even-money bet in a real money roulette game. After successive wins, stake €2 and then €4. Three wins produce €7 in net profit: €1 + €2 + €4. The €8 returned on the third winning bet includes that bet’s €4 stake, so it is not €8 in profit. Reset to €1 after the three-win limit or after any loss, provided it remains within your spending limit.

Parlay

Like Paroli, the Parlay system is based on a positive progression. The stakes are therefore always increased when the player records a profit. The Parlay System in roulette is similar in some ways to the Paroli strategy but has its own approach.

Not only the even-money chances can be played here. The player flexibly defines the stages of his game by defining both the starting stakes and the desired winnings. Every time you lose it, you go back to the first step. 

Parlay example: an initial €1 bet on red returns €2 if it wins. Rolling that €2 onto a dozen bet paying 2:1 returns €6 if it wins. Rolling €6 onto a six-number line paying 5:1 returns €36 if it wins. That is €35 in net profit from the original €1, conditional on all three bets winning. A loss ends this progression; the sequence does not improve the underlying odds.

D’Alembert

This strategy is about limiting losses and managing your stake in a disciplined manner. Although like Martingale, this is a negative progression, the progressions are much flatter. With the D’Alembert strategy, the player relies on even-money chances. In the beginning, a number of pieces/chips are defined, with one piece standing for a fixed amount. With every loss, a piece is added in the next run and with every win, the next stake is reduced by a piece.

Example of the sequence of the D’Alembert tactic: The player decides to place four pieces at the beginning of a D’Alembert run. If he/she has lost his first bet, he/she bets five pieces on the same chance in the next round. If there was a win, four pieces would be put down in the next run. If the player has won, the next time there are three pieces to be invested as a stake.

The Law of Small Numbers

With 37 equally likely pockets and 37 independent spins, the expected number of distinct results is about 23.6: 37 × [1 − (36/37)³⁷]. This is an average over repeated samples, not a promise that any particular number will appear. Choosing numbers because they appeared, or failed to appear, earlier does not change their probability on the next spin.

According to this roulette strategy you want to try to cover two-thirds of the numbers with one bet and hope that as many of these numbers as possible are actually drawn. Some players observe the table carefully and pick previous numbers for their bets. It’s not hard to guess that this strategy is solely dependent on luck but there’s still some entertainment value in following this system.

Marche

The Marche (French for “march”), is another popular type of betting technique in roulette. In a way, it has some similarities to card counting in blackjack. You keep a keen eye on all previous game outcomes and try to predict the probabilities of future outcomes. However, since there is no deck of cards with which to orientate yourself in roulette, each new round is completely unaffected by everything that has happened before. 

Even if Red has won ten times in a row, this does not mean that Red will have a higher (or lower) chance of winning in the eleventh round. Therefore, players who use the Marche roulette strategy simply place their trust in the hope that various statistical outcomes will occur. One such outcome is the law of equalization: if red won last, you bet on black, since from a purely statistical point of view, in the long run, red and black win about equally often. However, other players prefer to bet on past winners in the hope that a series will occur or continue. The problem is that statistics can’t really predict any outcomes on a roulette table in the short term. 

The Flaw of all Roulette Strategies

Betting progressions such as Martingale depend on being able to fund the next stake. Real bankrolls and table limits are finite: repeated doubling can require a bet you cannot place, leaving previous losses unrecovered. A hypothetical unlimited bankroll is not a practical winning strategy, and changing stakes does not remove roulette’s house edge.

This leads us to the next big problem. The elephant in the room is the table limits. Each casino game has a limit for the maximum allowed bet size. This table limit can be reached rather quickly and you won’t be able to double up your bet any longer. Therefore the strategy failed and you are left with a big loss. Some of the roulette strategies are still fun to try, but you should be aware of the risks!

How to Lose With a Progressive Strategy

A progression sets a target for recovering losses or building on wins, but it does not ensure that the target will be reached. A losing sequence can exhaust the available budget or make the next required stake exceed the table limit. Increasing stakes does not remove the house edge.

A losing sequence can exhaust your budget before a Martingale progression reaches a winning bet. Starting with a smaller stake delays how quickly the required bets grow, but it does not prevent a long losing sequence. On independent roulette spins, the game history cannot eliminate losses or make the next bet more likely to win. A table limit can also stop the progression before you recover previous stakes.

The table limit can stop a doubling progression even if the player could afford a larger bet. Past wins do not show that future spins will be lucky, and cashing out after a win does not turn a progression into a profitable system. Set a spending limit before play and stop when it is reached.
