In addition to the season-ending world championship, the Tom Clancy's Rainbow Six Siege competitive circuit features mid-season international S-Tier LAN events known as Six Majors. These tournaments bring together the top teams from the North America League (NAL), Europe MENA League (EML), South America League (SAL), and Asia Pacific League (APL) to battle for significant prize pools and crucial Global Standings points.

Since Ubisoft launched the modern Tom Clancy's Rainbow Six Siege esports circuit, the season-ending world championship—the Six Invitational—has stood as the absolute pinnacle of competitive achievement. Held at the conclusion of the competitive year, teams vie for qualification and Global Standings points within their domestic regional leagues to earn a spot at the most prestigious tournament in Siege.

Rainbow Six Siege, a name synonymous with tactical shooter excellence and esports prominence, was born within the creative walls of Ubisoft Montreal. This development studio, known for its innovative approach to gaming, took the reins in transforming Tom Clancy's legacy into an interactive masterpiece. The journey began in the early 2010s, with a dedicated team set on revolutionizing the tactical shooter genre.
