Hello, everyone, there are eight groups of basketball players. How to arrange the competition system and decide the ranking from the first place to the eighth place fairly and reasonably? How many times? I recommend a style of play: grouping+elimination!

Grouping: Eight classes are divided into group A and group B. Each class in the group plays 3 games (each class in the same group plays). The point system is: win 1 game, with 2 points. Negative 1 min. Abstain 0 points. Take the top two in each group and enter the knockout stage! (If the integrals are the same. Team 2 can play overtime.

Elimination: There are 4 teams in Group A and Group B, which can be A 1-B2 and B 1-A2. Play, 1 elimination. Until the final, those who didn't make it to the final will have another game. Divide into three or four parts.

There are four teams in Group A and Group B, which can be A3-B3 and B4-A4. Play, 1 elimination. Decide five, six, seven and eight.
