The new calculation formula of two-color ball is the most accurate.

A new method for calculating the formula of two-color ball is constant sign method.

Divide the red zone number of two-color ball into two parts, 0 1-1small and 12-33 large, and find out the group number of 16, which are 01,33, 02, 32 and 03 respectively. 10, 24, 1 1, 23, 12, 22, 13, 2 1, 14, 20, 15, 65438+.

It should be noted that the above methods are for reference only and cannot guarantee the accuracy of 100%. This number selection method can't hit four or five numbers in a cycle, but at least it can hit more than two numbers. Although there are 1-3 unknowns that do not follow this feature, if we observe these unknowns with long-term experience and skills, the accuracy will be even greater. We should pay attention to the rare opportunity and cannot copy them mechanically.

Two-color ball winning rules:

First prize: 6 red ball numbers+1 blue ball numbers.

Second prize: all six red ball numbers are correct.

Third prize: 5 red ball numbers+1 blue ball numbers.

Fourth prize: 5 red ball numbers are all right or 4 red ball numbers+1 blue ball numbers.

Fifth prize: 4 red ball numbers are all right or 3 red ball numbers+1 blue ball numbers.

Sixth prize: 2 red ball numbers+1 blue ball numbers or 1 red ball numbers+1 blue ball numbers or only 1 blue ball numbers.
