Is maths a thing in gambling? Can you use maths to win, or does winning depend on your luck and skill? You probably have asked yourself if you have tried or thought about gambling. Gambling is a game that started centuries ago and has been attributed to a player’s luck and skill. The evolution of gambling has led to the creation of casinos and numerous casino no-chance-based games and bonuses like free spins on registration no deposit 2022 uk. However, it’s true that gambling led to the evolution of some mathematical concepts.

Consequently, it’s true to note that the growth of gambling has led to the introduction of mathematics concepts. From probability (the most common mathematics associated with gambling) to more complicated concepts, it’s true that mathematics is used to win big in casinos. 

It’s important to know that you don’t have to be a mathematics professor to win at the best payout online casino. However, understanding basic mathematical concepts is vital if you are interested in reaping huge or increasing your probability of winning. This article tells you what you need to know about the use of maths in gambling and everything in between.

House Edge by Casinos

House edge, also known as a casino advantage, is a concept that exists in every land or online casino. It is an advantage the casino has over the players. To put it in simple terms, it’s the percentage the casino makes from every game you play and win. Take note of the following points:

  • A high house edge meant a lower payout for the player: For example, if the best dollar deposit casinos set the house edge at 2%, this means that on every bet you win, the casinos make 2% out of it. This advantage of the casino has meant a high probability of you losing in the long run. 
  • Table games such as poker, baccarat, blackjack, and roulette, among other games, are the most exposed to this concept. This is regardless of the best online casino you are using.

Use of Strategies in Gambling

The use of strategies to win in casino gambling developed long ago. Centuries ago, people realized that winning in casino gambling didn’t entirely depend on luck. So people started calculating how to maximize the winnings and not rely entirely on chance. 

Emperor Claudius of the ancient Roman Empire wrote a book of strategies to win when playing dice. Although the concepts he outlined back then may not fully work in the present day, the insight provided was very helpful to the advancements of different concepts later. 

The use of probability is also another concept that was developed centuries ago to help with gambling.

Mathematical Concepts in Gambling

The basic maths principles in casinos include probability, volatility index, and expected value. These mathematical concepts were developed to solve gambling problems. However, it’s important to note that different concepts apply to various casino games, and the success rate will also differ in different games. 

Probability Concept

Italian Physician Gerolamo Cardano wrote a gamblers’ manual about the “Sample Space” in the 16th century. This was the birth of Probability theory, widely used in Mathematics and Physics concepts today. The manual outlined how the outcomes when playing dice were not entirely based on luck; you could maximize or predict your chance of winning. 

The game of dice was so popular back then, and he was also a lifelong gambler. The sample space concept outlined all possible events when the die was tossed. For example, he noted that when a die is tossed, the sample space is 6. So the probability of a face (say six) showing up was 1/6.

Expected Value Concept

The expected value is the multiplication of the probability of a particular event happening by the number of times the event happens. In other words, the expected value shows the overall amount a player expects to win or lose. 

It was developed by mathematicians Blaise Pascal and Antonie Gombaud to solve the problem of points encountered in gambling. So, how was it used in gambling? It determined the amount each player would get if the game ended before anyone attained the required winning value.

For example, if a coin is tossed and whoever gets five heads wins, but the players quit the game on a score of 4-3, then the expected value was used to determine how much each player wins.

This concept has been developed and is used in finance and economics to calculate the expected value of an investment. This way, an investor can choose between two investments they have on their list.

Volatility Index Concept

Another word for volatility index is the standard deviation. The volatility index determines the chance of winning an amount less or more than the expected value. It is correct, therefore, to say that a volatility index quantifies luck. The players are attracted to gambling by the probability of winning higher amounts than the expected value. This is regardless of the likelihood of losing big.

Can the Use of Maths Help You Win?

Can you use maths to win? The answer is already yes. Although gambling is mainly attributed to skill and luck, most people gamble for fun or to test their luck. As noted earlier, you can use maths to win big. Moreover, you do not entirely have to rely on luck. Most of these casino games are developed using the same mathematical principles.

From understanding the game theory to counting cards when playing blackjack, maths always plays a crucial role in gambling. Different systems have also been developed over the ages by players to help them win large stakes in casinos:

  • Betting on more than one number in roulette is one of the systems. 
  • Another system counts the number of cards to predict the probability of a particular card being drawn. This strategy was used by a group of MIT students in the 90s to win large Las Vegas casinos. This can still be applied in today’s casinos.

When playing in casinos, however, you should take note that some mathematical principles, if they are not used with caution, can lead to bankruptcy. An example of this is the Martingale system. This system states that you double your wager each time you lose a bet. Therefore, it would be best if you learned to balance your betting strategy and know when it’s safe to quit playing.


Many people might argue that luck and not maths are what is needed in gambling. However, the connections between maths and gambling started long ago. Many maths concepts have been developed to try to solve gambling. At the same time, gambling has led to maths development, as noted previously. It’s, therefore, essential to note that as much as gambling depends on skill and luck, including maths in gambling will always increase your chance of winning. Gambling is not only an art but also a science, and maths will help you win.
