How would I go about making a ranking game?

How would I go about making one of those games that automatically ranks you using a bot? It’s probably very complicated but I would like to know about the process. E.g an application center that after you pass subsequently ranks you to “Trainee”.

They use third party applications to rank people up. I would assume most of them use a platform such as GitHub or Glitch in order to create such scripts, but some more experienced programmers create their own websites.

Either way, a quick Google search may bring up results relating to your topic.
