Roulette is one of the oldest and most popular gambling games, with players all over the world trying to beat the odds and hit big payouts. One popular roulette betting system used by many players is the 'Law of the Thirds.' In this article, we'll explain what this system entails, how it works, and whether or not it's a reliable way to win at roulette.


What is Law of the Thirds roulette betting system?

The Law of the Thirds is a roulette betting system that is based on the principle that in any 36 consecutive roulette spins, approximately two-thirds of the numbers will appear. This system is created to help players take advantage of this statistical likelihood to make more informed betting decisions.

What is the theory behind the Law of the Thirds roulette betting system?

A roulette betting strategy known as the Law of the Thirds is based on the notion that, over the long term, the ball will roughly land on each of the 38 numbers (or 37 in European roulette) with the same frequency. As a result, each of the 38 (or 37) numbers will show up roughly one-third of the time in a set of 37 spins. This indicates that the chances of picking the correct number on the following spin are 1 to 38 (or about 3%).

Yet, if you plot the distribution of the numbers over the 37 spins in order, according to average statistical data, about 2/3 of the numbers (let's say about 25) will appear once or more. So, 1/3 of the wheel's numbers will not show up at all, but there is a chance that 2/3 of them may appear again.

According to these stats, 15 numbers may repeat every 20 spins whereas just 6 may do so every 9 spins. The strategy, known as the Law of the Thirds in roulette, is based on the idea that at least one of the six numbers might show up more than once in every nine spins.

How does the Law of the Thirds roulette betting system work in practice?

Based on the results of previous spins, the Law of the Thirds roulette betting technique includes placing bets on specific numbers of the roulette table. The theory is that outcomes of previous spins may repeat during the definite number of the next spins.

One common approach behind the Law of the Thirds theory is placing straight up bets on numbers that has been in outcome of 9 previous spins during the specified number of subsequent spins in a row,

Using Law of the Third betting system to place straight up bets:

  1. Track the results of each wheel spin. Wait for 9 distinct numbers to appear during the sequential wheel spins. If your game version does not have the board of previous spin results, place bets on even bets (like red or black, even or odds) and track spin results.

  2. Then, skip a few more spins. This is called a “safety stop”.

  3. Place equal bets on all 9 numbers during the next 3 spins.

  4. Repeat the betting session.

The cost of your betting session is 9x3 bet units, which is 27. The straight up bet pays out 35 bet units in case of win. So, your benefit is 8 bet units, if at least one of the numbers will repeat.

Are there any risks associated with using the Law of the Thirds roulette betting system?

Certainly, using the Law of the Thirds roulette betting system carries some risk. Despite the system's apparent rationality and simplicity, there is no assurance that it will consistently produce victories. There is no way to anticipate with precision which numbers or areas of the wheel will hit because roulette is a game of chance and each spin of the wheel is independent of the previous spin. However, if a player uses the Law of the Thirds strategy and goes on a losing streak, they risk losing a sizable sum of money very rapidly. You should always gamble sensibly and never stake more money than you can afford to lose.

Does the Law of the Thirds roulette betting system guarantee a win?

The type of roulette being played determines the chances of success while employing the Law of the Thirds betting technique. The chances of winning on any one bet in American roulette, which includes 38 numbers (0, 00, and 1-36), including wagers on one-third of the numbers, are 1 in 38.
The odds of winning are higher with the Law of the Thirds approach than with a single-number wager since you can wager on many numbers at once. You cover 9 of the 38 available numbers, or around 23% of the board, if you wager on one-third of the numbers. Using the Law of the Thirds technique over the long term, you can anticipate winning around 23% of the time.
It's critical to keep in mind that these probabilities are based on mathematics and do not ensure a win or loss on any particular spin. The odds of winning or losing do not change as a result of using the Law of the Thirds technique; each spin of the roulette wheel is a separate event. The Law of the Thirds is merely a bet strategy based on a statistical observation, and as with all bet strategies, it has risks and is subject to uncertainty. The Law of the Thirds cannot alter the fact that each spin's result is ultimately determined by chance, even though it can increase a player's odds of winning in the short term.

What are some common mistakes to avoid when using the Law of the Thirds roulette betting system?

When employing the Law of the Thirds roulette betting system, it's important to avoid some common mistakes, such as:

  • Chasing losses: it's vital to stick to your betting strategy and avoid raising your stakes in an effort to make up lost ground.

  • Failure to establish a budget: before employing any betting strategy, it's critical to do so. Don't keep betting more than you can afford.

  • Failure to take variation into account: there will always be some level of unpredictability or randomness in the game, even with a strong betting strategy. It's critical to realize this and avoid getting overconfident or disheartened by immediate results.

  • Ignoring the odds: while the Law of the Thirds might be a useful tactic, it's crucial to keep in mind that there is always a chance of winning on any given bet in roulette. Don't get too sure of yourself or think you'll win every time.

Roulette games restrictions by local markets regulations:

It is crucial to keep in mind that not everyone can always access the roulette games. For instance, roulette games are currently not available to players who are residents of Germany. Some players, especially those who have previously loved playing these games, could find this restriction disappointing. But it's crucial to realize that these limitations are there for a reason, and they're essential to ensuring that online gambling is done fairly and responsibly. Despite this restriction, gamers in Germany have access to a large range of other thrilling games, including a selection of slot machines and arcades.


Due to its ease of use and ability to boost earnings, the Law of the Thirds betting system is a well-liked tactic among some roulette players. Success is not assured, and there are dangers as with any betting strategy. It's crucial to use the system appropriately and to approach the game with a thorough grasp of it. Before using the strategy with real money, it is advised to practice it in free play mode.
