## True round-robin tournament

Mark G asks in Create a random playlist in excel:

Can this example be modified to create a true round-robin draw?

i.e. using a 6 team scenario, for any round there will be three games/matches, but obviously, Team A could not compete against say Team B and Team C during that round as can occur using the above formula.

**Answer:**

This example is based on a double round-robin in which every team plays all others in its league once at home and once away **randomly**.
