In the start, people suggest users to fill the space up, in this case it is 100 users. and each are divided into a specific amount of groups (in this case ten) and among those groups, 1 is being voted on. There are usually only two modes, Vote to Save, and vote to eliminate. Vote to save is where you vote your favorite user in the group. last one saved is eliminated
In vote to eliminate, the user with the most votes is elminated, there can sometimes be multiple votes, meaning you can vote more users (usually up too three votes) and 1-3 eliminations.
