The number of trial runs usually has a peak, which is the largest number in three digits. Usually at 8 or 9, the skill probability is higher. Here, let's analyze it with reference to the results and trial run times of issue 201919.

The trial run number of 20 19 1 19 is 282, and the peak value is 8. Then add two small values, 2+2 equals 4, and the decomposition peak is a number where the sum of two numbers equals 8. They are 17, 26, 35 and 44 respectively. There are many trials of 2, so we will focus on 2 and multiples of 2. There are 26, 44 and 35 respectively, so this number must have two numbers plus a small value.

The trial machine number refers to two lottery machines (1 No.2 and No.2) and two lottery balls (1 No.2 and No.2) generally prepared in the 3D lottery hall of Welfare Lottery Center. At about 6 o'clock every night, the 3D lottery hall of Welfare Lottery Center will use a set of machines and a set of balls to test the machines and balls first, so this number is called the test machine number.

For example, the trial number of this issue is: 2 machines and 2 balls 8 17, which means that today's lottery will use 2 machines and 2 balls, and the trial number is 8 17. The lottery number of the day is to shake out the lottery number of the day with the tester number and test ball of the lottery machine.
