Matching 2 random users from a list of 24 users and creating 12 groups

I am building an app in which users can join gaming tournaments and also challenge each other for box and ps4 gaming.

Here is the flow - when a user joins a tournament of 24 members, he is added in the tournament as a player.

A match happens between 2 people. I want to understand how I can create 12 matches between these 24 players and also create a winning structure in which the winner goes ahead.

We wouldn’t be able to randomize the users. You could likely have the ability to set 24 users have them select who they would go against (not at random) and then have a winner true/false which would move them forward to the next round and then keep this trend moving forward. Will likely take a fe databases and relationships to each other.
