# Roulette strategy and betting strategy

Albert Einstein once said: "Unless you steal money from roulette, you can't beat roulette."

Nevertheless, many even-sum bets on roulette have prompted many players to try to beat the game over the years using one or more variations of the ** Martingale strategy**, in which players double their bets every time they lose , So the first win is all previous losses and the allowed win equals the original bet.

As the Martingales article shows, this betting strategy has fundamental flaws in practice. In the long run, the near-universal consequences are considerable financial losses. Another strategy is the Fibonacci system, which calculates bets based on the Fibonacci sequence. Regardless of the progress, it is impossible to statistically defeat the casino advantage.

Although not a money-making strategy, Andrés Martinez, the editor-in-chief of the Los Angeles Times, described an enjoyable roulette gambling method in his Las Vegas book "24/7" He called it a "confused experiment." Roulette funds are divided into 35 units, which bet with a given number in 35 consecutive actions, so if the number appears in these actions, the player will win his original funds and can continue to use his own funds . In 35 actions (with double zero rounds and 38 squares) only (1â((37/38) 35) * 100% = 60.68%.

There is a misunderstanding that green numbers are "house numbers", and bets on them "win the house advantage." In fact, the advantage of the house does come from the existence of these green numbers (a game without statistically green numbers will be fair). However, compared with any other issues, they have few chances of being released, and they are not many.

Engineers have tried many times to overcome the advantages of the house by predicting the mechanical properties of the wheels, the most famous being Joseph Jagger in Monte Carlo in 1873. These plans work by determining the number at which the ball is most likely to "pause". Mathematician and computer scientist Claude Shannon (Claude Shannon) is known for his contributions to information theory, he undoubtedly made the first laptop that could do this in 1961.

To prevent such attacks, the casino monitors the performance of the wheels and regularly rebalances and realigns the wheels to ensure that the spin results are as random as possible.

Recently, Thomas Bass claimed in his 1991 "The Eudaemonic Pie" (published at the Newton Casino in England) that he could predict the performance of wheels in real time. The book describes the use of a group of hackers who call themselves "Eudaemons" who used computers hidden in their shoes to win roulette in the late 1970s by predicting where the ball will fall. .

In the 1930s, some professional players could continue to gain roulette advantages by looking for fake wheels (which were easy to find at the time) and betting larger bets.

In the early 1990s, Gonzalo Garcia-Pelayo used a computer to model roulette trends in a casino in Madrid, Spain. By betting on the most probable number and his family, he has won more than one million euros in prize money over the years. When the casino questioned the legality of his strategy, the court ruled in his favor.

According to reports, in 2004, a team of two Serbs and a Hungarian in London used a scanner hidden in a cell phone connected to a computer to predict the area where bullets are most likely to fall on wheels. stop. They were arrested and released for free because there was no evidence that they had technically interfered with casino equipment.

**Bet only red**

The conceivable strategy is to bet red on a certain number of spins (for example 38).

There are a total of 18 red squares on the roulette wheel, a total of 18 red squares. Dividing 18 by 38 gives the probability of red appearance, which is 47.37%. This probability can be used in the binomial distribution and converted to an approximate standard normal distribution.

This operation shows that if you turn the wheel 38 times, the probability that the ball will land on the red at least 10 times is 99%. In 38 hits, the probability of the ball hitting red at least 15 times is 83%. Over 38 laps, there is an 18% chance of red appearance being 50%.

However, the key point is 19 moves, because the bet on red is 1/1, and the probability of red in 19 out of 38 moves is only 37%. This shows that it is difficult to win the game just by betting on red.

This result occurs because formula 18 divided by 38 equals 47.37%, which means that the ball will fall on red in less than half of the time. The percentages applied to the binomial and standard normal distributions create a large gap in the probability between the 18 red spins and 19 of the 38 red spins. In 38 spins, it is unlikely that anyone will get more than 18 red spins.

**Multiple bets**

This type of betting is a combination of red betting and the system. The difference is that this bet also includes odd numbers. The strategy starts by betting 1 on red and odd numbers (or betting on black and even numbers). Each bet will be processed separately. When the bet fails, it will be doubled. When a bet wins, it is reset to 1. The reason for this is because the technology allows players to stay in the game for so long, because there is almost a 25% chance of winning red and red. Odd number, the chance of being tied is almost 50% (win one bet and lose another).

Of course, for this method to continue, players need an unlimited source of funds"...! In fact, this method will have the opposite effect when the player no longer bets and loses. This loss may be a loss Also, in the long run, because the house always has an advantage, players will lose money like all other unparalleled casino games.

**Use the dozen bet**

The system has two versions, singles and doubles. In the singles version, players use an increasing bet list, starting with the minimum value of the casino table and continuing to the maximum value of the table. The goal here is to use a dozen to win before the betting list ends. Many techniques are used, such as: betting on the same bet after appearing twice in a row, betting on the bet with the most occurrences in the last 15, 9 or 5 moves, betting on betting turns that have not appeared for a long time or more , Appeared for the first time. The doubles betting version uses two betting, which is half the size of the singles betting version list.

**Strategies in the first and third columns**

The 2-chip bet on the first column and the 2-chip bet on the third column cover most of the red numbers on the table. If there is a black number, betting on black with 2 chips will provide insurance. The betting system covers almost all numbers, except for the four red numbers and zeros in the middle column (double zeros in American roulette). If the result is a red number in the first or third column, the player is breaking even. If the result in the middle column is red, the player will lose 6 tokens. If the result in the middle column is black, the player will lose 2 tokens. If the results in the first and third columns are black, the player only wins 4 tokens.

**Mechanical strategy**

In certain ** roulette strategies**, more mechanical skills are needed to beat the casino. The most famous is the oblique round attack. In a deflection wheel attack, players time the wheels to determine statistical deviations that indicate certain wheel failures. Since roulette is made by humans, it is almost impossible for a roulette wheel to be perfect. A biased wheel attack will look for imperfect wheels and take advantage of the fact that certain wheels often appear more than one in 35, which means there may be an advantage over the casino. Timing the wheels includes a lot of recording the results of each lap in order to spot any opportunities.
