# History

Since ancient times, the gambling has stimulated the interest of the distinguished mathematicians and scientists in the aim of being able to dominate the randomness of the game. Napoleon used to say: “There will come a day that the calculation will win the case!”

## The systems history

We can not say that this day has come, but it is certain that if it has not won it certainly tamed. The studies have helped to establish some basic concepts on the basis of which have been developed most of the systems used by players.

Just to mention one in all “The law of large numbers” defined by the mathematician Bernoulli, which states: “In a series of tests, the possibility that an event will occur at least once increases with the extension in the number of tests provided in each of them is likely to occur.”

But it is also true that the roulette wheel has no memory, every shot is new and does not take account of the preceding which theoretically nothing prevents to appear the same number, or an ordered series of numbers (eg. all red). Well this is a point that comes into play overbearingly statistics.

Since there is roulette no player has seen the draw of the same number (it is said that the record has a maximum of 6 times, very rare event), or an uninterrupted series in the same color (other record which is not confirmed of 36 shots).

We do not want to dwell further in presenting mathematical concepts and rules that have contributed to the finalization of many theories but we prefer, in the interest of the reader, merely to identify the main types of systems.

We can divide the systems into three broad categories:

• systems with progression in win;
• equal mass systems
• systems with progression in the loss.

## Systems with progression in win

These are systems that base their effectiveness in the implementation of an increase in stake each winning spin and keeping the same bet or returning to the initial stake at each blow loser in waiting to meet a wave that allows the player to achieve a positive result. These are systems that can lead to high gains but also those who may have high exposures. In the section “The best-known systems” are described some of the most popular.

## Equal mass systems

These are systems that always offer the same episodes in the hope of having a gap in favor. These are systems that greatly restrict the exposure of capital and the risk of large losses, but they are also those who have a real chance of success need to present a substantial deviation before starting the game. As is known, one of the most difficult to define is the value of the deviation and the ideal time to start playing.

## Systems with progression in the loss

The vast majority of systems belong into this category. They are designed to achieve a predetermined results having as main characteristic the increase in bets to recover the negative deviations that the system may have encountered. Some are more or less aggressive, others are aimed at achieving the minimum goals with great resistance to the negative phases. It is in this area we have concentrated our efforts to implement the program we propose.
