Counter-Strike: Global Offensive Major Championships
Starting in 2017, the group stage would feature a Swiss group stage. This would mean teams would be divided into four pots, in which pot one had the four highest seeds, pot two had the next four highest seeds, and so on. A randomly selected team from pot one would face off against a randomly selected team from pot four. The same process is done with the pots two and three. After initial matches are done, teams with the same record would play, so that teams with a 1-0 record would only play another team with a 1-0 record. If a team gets three wins, then that team moves on to the next stage. If a team has three losses, that team is eliminated. All games were best of one up until the FACEIT Major: London 2018. The Boston 2018 Major featured two Swiss group stages; the stage formerly known as the offline qualifier was now known as the New Challengers stage and the group stage was now known as the New Legends stage. The Swiss system also guarantees no team would face each other twice unless necessary. The revealed a slightly different form of the Swiss system called the Buchholz system, in which matchups would now be seeded instead of random and the last round would feature best of three sets. The next Major featured an Elo system, in which teams would rank the other teams they would potentially play in the group stages to create a ranking system, thus getting rid of randomization.
