The winner of each season's finals goes on to participate the Global Finals at the end of the year, as well as winners of other prestigious non-BLAST Premier events and those that rank highest in the BLAST Premier Global Leaderboard, a standings of the top events of the year from multiple leagues and tournaments.
[4] In August 2023, Counter-Strike developer Valve announced that the partnership system that Blast Premier used would be abolished in 2025, forcing all tournament organizers to pivot to an open circuit or an invitational system using Valve's rankings.
To align with Valve's new rules forcing their partnership system to cease, BLAST will use three formats - Bounty (a 32-team invitational tournament where teams receive bounties for winning matches against their opponents), Open (a 16-team tournament mimicking the Intel Extreme Masters), and Rivals (where the top 4 teams in the Valve rankings, plus the next-best teams in Europe, the Americas and Asia) will play each other in the old Final format).
[10] In August 2023, Counter-Strike 2 developers Valve banned tournament organizers from having "unique business relationships" with teams.
"Rivals" tournaments involve eight directly invited teams competing in four-team double-elimination brackets, before a best-of-five grand final.
