ACR Poker’s $50 million guaranteed Online Super Series XL has already generated $22.3 million in prize pools after its first week, and the biggest events are just getting started. Three Main Events with a combined $5 million in guarantees launched Day 1A flights yesterday (March 15), with Day 1B still open this Sunday, March 22.

The early headline came from the Phil’s Thrill XXL, a $10,300 buy-in high roller that crushed its $1.5 million guarantee and paid out over $2 million.

With the Main Events, a $1.5 million multi-flight, multiple mystery bounty events and a $65,000 leaderboard contest still on the schedule, the final week is where the real action concentrates. Here’s what’s happened so far, what’s still to come, and how to get into the Main Events through ACR Poker with the best deal available.

OSS XL Passes $22 Million in Prize Pools After Week One

The OSS XL is ACR Poker’s flagship online tournament series, running March 1 to 23 with more than 750 events across every buy-in level from $0.55 to $10,300. ACR confirmed the $22.3 million first-week figure via a March 12 press release, with the series not yet at the halfway point when that number dropped.

Key numbers heading into the final week:

The momentum follows ACR’s Dual Venom tournaments earlier this year, which paid out over $11 million.

The series opened with a bang when the $10,300 Phil’s Thrill XXL drew 206 entries and generated a $2,060,000 prize pool, beating its $1.5 million guarantee by 37%. For the full OSS XL schedule breakdown and mystery bounty details, check our series preview.

$5M in Main Events Now Live: Day 1B Is This Sunday

The centrepiece of the OSS XL is three Main Events with a combined $5 million in guarantees. Day 1A flights ran yesterday (March 15). Day 1B flights are this Sunday, March 22, and Day 2 for all three events is Monday, March 23.

The $215 Main Event with its $1 million guarantee is the accessible entry point for mid-stakes grinders. The $1,050 and $2,650 events both guarantee $2 million and attract a mix of regulars and recreational players taking shots during series week.

What Else Is Left on the Schedule

The Main Events are the headline, but the remaining schedule is stacked with value across every bankroll level.

Most final flights and Day 2s concentrate on March 22 and 23, making this coming weekend the single biggest stretch of the entire series.

ACR’s recent track record with large-field series has been strong. The Dual Venom tournaments earlier this year set entry records, and the Phil’s Thrill XXL result suggests the OSS XL is following the same trajectory.

$65,000 Leaderboard: Extra Value Through the Final Week

Running alongside the full tournament schedule is ACR’s $65,000 Leaderboard Contest, funded entirely by ACR and not deducted from any prize pool. It rewards consistency across the series, with separate tiers so grinders at every stake level have a realistic shot.

For volume players grinding multiple events per day, the leaderboard adds meaningful EV on top of every cash. Even if you don’t bink a headline score, consistent deep runs across the final week can put you in contention for thousands in extra prizes.

ACR Pro Jon Pardy is putting that theory to the test with a 120-hour live grind of the series, featuring giveaways and bankroll challenges for viewers on stream.

How to Play the OSS XL Through VIP-Grinders

If you’re registering for the OSS XL Main Events or any of the remaining schedule, signing up through VIP-Grinders with code VIPELITE gets you significantly more value than going direct.
