ROBLOX Any way to make personal places for different games?

In games like NOTORIETY and such, you can create a Contract witch leads you to a place titled [PlayerName] Server, I Want to figure out how to do something like this, so every player has their own specific server that they can play without anyone else joining through the server tab in the game, and so I can personalize the server they inhabit. Thank you in Advance, I will freely answer any questions!
