A reducing system of setting applies to the games to combination. It is thus the case of the lotteries, tiercé or the lotofoot for example. For all these games it is necessary to find a combination single to gain the batch of first rank, but of other secondary batches are offered for similar combinations. A system of reduction of settings does not make it any possible additional to gain the first price but it will optimize the chances to obtain a secondary batch without to increase considerably the settings necessary.

Let us take an example for specifying the things well. With the new lotto, one chooses 5 balls between 1 and 49 and one number chance between 1 and 10. One gains starting from 2 gaining numbers. The player has decides to play a first grid with numbers 1,2,3,4,5 and the number chance 1, and a second with the same numbers and the number chance 2. The player B decides on his side to play the 1, the 2, the 3, the 4, the 5 and the number chance 1 on his first grid and the 6, the 7, the 8, the 9, the 10 and the number chance 2 over the second. Both have as many chances (two on more than 19 million) to gain the batch of first rank. But by diversifying his numbers the player B will have more chance to have for example two gaining numbers. Indeed if the grids of the player has reveal 10 couples of possible numbers (1/2, 1/3, 1/4, 1/5, 2/3, 2/4, 2/5, 3/4, 3/5, 4/5), the player B will have 20 of them (1/2, 1/3, 1/4, 1/5, 2/3, 2/4, 2/5, 3/4, 3/5, 4/5, 6/7, 6/8, 6/9, 6/10, 7/8, 7/9, 7/10, 8/9, 8/10, 9/10) and thus twice more chance to have two gaining numbers.
In this example one did not use a system of reduction of setting, but simply illustrated the interest to choose with logic the played combinations.

The systems of reduction of settings apply to the games with combination. Here some examples of games where one can apply them.

• Lotteries: lotto, euromillions, keno, but also all the lotteries on Internet
• Sets of sporting lottos
• Horse betting

According to the games various parameters can be used. For the lotteries one can bring a preselection of numbers and indicate a rate of guarantee. Idem for the games of sporting lottos. For the horse-races one can generally moreover specify the number of bases, i.e. the number of “sour” numbers, played systematically.

Here some reducing systems of settings available on Internet.

• redumiz.com: a tool free and easy to apply. The system is adapted for the most popular games
• ecomulti: paying software

First of all it should well be integrated the fact that these systems do not change to in no case the probabilities of gaining the profit of first rank. Moreover if these systems increase the frequency of the profits, for games with fixed statistics (like the lotteries), they statistically do not increase the profits. Let us take again the preceding example to be convinced some. It was seen that the player B were likely more to gain but if the player has a gaining combination, it gains twice more since the 5 numbers are the same ones in the two combinations. At the end of the day it is thus noted that these systems do not bring additional profits on the long run.
In fact these programs are especially useful for the games or the chances are not mathematically established. It is the case for the hyppic races. If you have elements allowing you to establish a preselection, then this software vousz will help to establish a reduced structure of settings based on this preselection.
