    I have a sports competition where each player has to play 5 matches against different opponents. I have 14 players which means a total of 35 matches (I think). So I need a list of 35 unique random pairings where each player appears only 5 times. Any tips, or recommended online tools?

    Your setup reminds of the Swiss System format in chess tournaments:

    It's not exactly random, as you requested, but it is one way of pairing the players for 5 rounds with no repeat opponents.

    Many chess federations publish pairing tables for tournaments. Here's the English one:

    You can simply use the first five rounds and ignore the rest.
