$50M OSS XL Ignites ACR Schedule

The OSS XL festival guarantees $50,000,000 across its schedule, making it one of the biggest online poker tournament series of the year. Hundreds of events will run during the promotional window, including multi-flight tournaments, Mystery Bounties, high-stakes showpieces, and value-driven mid and low buy-in opportunities.

At the heart of OSS XL are three flagship main events combining for $5 million in guarantees. These marquee tournaments anchor the series and provide serious upside for players targeting deep runs in large-field online poker events.

The first major flight takes place Sunday, March 15 with a $2,650 buy-in and a $2 million guarantee. The second flagship flight runs Sunday, March 22 at a $1,050 buy-in with another $2 million guaranteed. The series concludes with a $215 buy-in Day 2 finale on Monday, March 23 carrying a $1 million guarantee. This tiered structure allows players at different bankroll levels to compete for major prize pools within the same championship framework.

Mystery Bounty Action and Multi-Flight Value

Mystery Bounty tournaments continue to dominate the modern online poker landscape, and OSS XL leans heavily into that demand. Three separate $109 buy-in Mystery Bounty events each guarantee $500,000, creating recurring opportunities throughout the series to chase large bounties and headline payouts.

Lower-stakes players are not left out. Additional Mystery Bounty editions start at $33 with $150,000 guaranteed and even $5.50 with $100,000 guaranteed, expanding access across bankroll levels.

A $630 Regular Multi-Flight event boasting a $1.5 million guarantee runs throughout the series with Day 1s from March 1 to March 23, followed by Day 2 and the final table immediately after. Meanwhile, a $66 buy-in Main Event with $250,000 guaranteed provides another strong value spot on the calendar.

For high-stakes specialists, Phil’s Thrill XXL returns with a $1.5 million guarantee and a $10,300 buy-in. Satellites begin at $95, giving ambitious players a pathway into one of the largest buy-in events of the festival.

$65,000 OSS XL Leaderboard

Beyond individual tournament prize pools, OSS XL introduces a $65,000 leaderboard competition running the full length of the series. Points are awarded based on tournament finishes, and live standings are updated in real time.

The leaderboard is divided into High, Medium, and Low buy-in categories, ensuring that players at every bankroll tier have a realistic shot at additional rewards. High buy-in competitors can chase a $15,000 first-place prize, while Medium and Low divisions offer substantial payouts in a mix of cash and tournament tickets.

For grinders putting in consistent volume, every deep run carries additional value beyond standard payouts. Over a 23-day stretch, leaderboard equity can meaningfully increase overall expected value.
