How to organize 13 people to play table tennis?

This should be arranged according to the actual situation of the venue (number of tables) and time. Generally, it is 1 ratio 2, 3 to 4, 5 to 6, and so on. I'll give you a few options to choose from (it takes about 30 minutes to win three out of five games per game):

1. Great cycle: 13 people have to play 78 games, which takes about 39 hours. (Of course, if several stations play together, the time will be divided according to the number of stations. )

2. draw lots to decide the game. (Take out No.2, No.7 and 15 before drawing lots, so that the winners of 1, No.8 and 16 are equivalent to seed players, and there is no need for the first round of competition. ) the first round of elimination, successfully entered the next round of the cycle. It takes about 16.5 hours to play 5+28=33 games in a round.

3. On the basis of 2, we will continue the knockout round, eight into four, four into two, and then the third and fourth finals and the championship and runner-up finals. In this way, it takes about 6.5 hours to play 5+4+2+2= 13 games.

Note: The above time is calculated as 30 minutes per game, and there is only one game table. This data is for reference only and may not be accurate!

The specific arrangement depends on the actual situation and actual operation. I wish you a smooth game and a complete success!
