Operation method
Not all the underdogs and not all the hot ones. It is necessary to compare whether the ball appears continuously in several periods. Generally, there are many omissions, and there is a great possibility that the number will be continuously issued.
Two zones have been opened, so you can choose a number next time.
Zone 4 is the best time for periodic selection, because previous lottery draw 30-33 often appears.
The last issue was 2, 9, 16, 21, 30 and 31. Don't list the above numbers when selecting the number for the next issue.
It is better to keep the number of basketball players. For example, if the number of basketball players is 2, the number of basketball players is 7 and 12, try not to change it. Wait until one of the two numbers is issued, and then keep the other numbers.
