Rainbow Six Siege esports: the game and its pro scene
How does Rainbow Six Siege esports work? The game, Ubisoft's pro circuit, the Six Invitational and the Majors, and where to watch, with our sources.
What is Rainbow Six Siege?
Rainbow Six Siege esports is built on Tom Clancy's Rainbow Six Siege, a tactical team shooter that Ubisoft Montreal developed and Ubisoft released in December 2015. In each round, one squad of five attacks while the other defends, and the sides swap roles during the match.
Defenders fortify rooms with reinforced walls, barricades and traps; attackers send drones ahead to find enemies and the bomb site, then force their way in, sometimes through a window or the floor above. Much of the scenery can be destroyed, so blasting open a wall to create a new angle is part of the plan, and each team adapts its approach to its operators and the map.
A free access mode offers quick and unranked matches with a selection of operators; ranked play, the other operators and cosmetics are paid content.

How does the Rainbow Six Siege pro scene work?
Ubisoft runs the professional circuit. Each season starts in April and ends the following February at the Six Invitational, where the world champions are crowned. Along the way, teams compete in regional leagues, at the Majors and at the Esports World Cup.
In the 2026 season, Ubisoft lists five regional leagues: North America, South America, Europe and the Middle East, Asia-Pacific and China. League and Major results earn SI points in a Global Standings ranking that hands out most Six Invitational places; the Esports World Cup winner and the winners of open Last Chance qualifiers take the rest. Between seasons, regional Challenger series give new teams a way into the leagues.
Official matches usually go to a single map or a best of three or five. A map is won by the first team to seven rounds with a two-round margin; at six-all, the first to reach eight takes it. Ubisoft reworks the circuit each season, so check its esports site for the current format.

What are the biggest Rainbow Six Siege tournaments?
The Six Invitational closes the season and crowns the world champions.
The Majors are the season's international events. In 2026, the four strongest teams of each region qualify for them; the Osaka Major, run under the BLAST banner in November 2026, is set to go from a play-in to a Swiss phase, then a knockout stage ending in a grand final.
The game also appears at the Esports World Cup, and in the 2026 season its winner earns a direct ticket to the Six Invitational.
How can you watch Rainbow Six Siege esports?
Ubisoft's official esports site is the reference for news about the circuit and its formats. Matches are broadcast live on the official Rainbow Six Esports channels on the main streaming platforms.
