How to arrange the badminton match for six people?

One: six people play round robin, that is, each person plays five games and scores the ranking.

1 v2 1 v3 1 v4 1 V5 1 V6 2V3 2V4 2V5 2V6 3V4 3V5 3V6 4v 4 V6 5v 6

A *** 15 game

Two: First, draw lots to play three games, such as 1V2 3V4 5V6, which is fair, so you need to draw lots to decide.

Then, the three winners will make a round trip to get points, thus calculating 1 2 3.
