Hello, my friend, I want to consult you after seeing your answer about billiards! !

In the current national standard 16 lottery rules, it can be judged as unsuccessful in the following situations:

1. Our last goal kick and No.8 ball were bagged at the same time or successively.

2. Shoot down your target ball and bring in a black "8".

3. Hit the No.8 ball off the table (except at tee time). .

4. When playing the No.8 ball, the goal bag is not the designated bag.

5. One blow made our last goal and No.8 ball into the bag at the same time or successively.

6. When playing the "8" ball, the cue ball falls into the bag or falls into the bag at the same time with the black "8"
