Complete the 5v5 Tournament in Rainbow Six Siege without stress!
The Siege Cup is a new competitive format that gives every player a chance to prove themselves in a professional environment. These tournaments reward Competitive Coins, which can be exchanged for exclusive cosmetic items unavailable anywhere else. The challenge, however, is that entry requires a full 5‑player squad and strict preparation before the start. KingBoost solves this problem by providing experienced teams who carry you through the tournament straight to the top.
During the boost, our squad ensures your Cup completion and top placement, while your account benefits from a strong winrate and polished statistics. Every match contributes naturally to Battle Pass progress, so you gain long‑term value alongside the immediate rewards. The service is performed by professionals who either play directly on your account or integrate you into their squad, depending on your preference.
Available across PC, PlayStation, and Xbox, the service is flexible in pace: you can choose a natural progression that feels steady or opt for fast‑track completion if you want results right away. With KingBoost, Rainbow Six Siege Cup Boosting becomes safe, efficient, and rewarding — victories and rewards are guaranteed.
50,000+ players trust us. That number isn't luck—it's the result of years of consistent delivery, professional boosters and a support team that cares about your experience.
Here's what makes us the best at what we do:
