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:
- $50 million in total guaranteed prize pools across the series
- $22.3 million generated in week one alone
- $5 million in Main Event guarantees launching now (three events)
- $65,000 leaderboard contest running alongside the full schedule
- Buy-ins ranging from $0.55 to $10,300
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.
| Event | Buy-in | Guarantee |
|---|---|---|
| Main Event (High) | $2,650 | $2,000,000 |
| Main Event (Mid) | $1,050 | $2,000,000 |
| Main Event (Low) | $215 | $1,000,000 |
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.
Day 1B flights run this Sunday, March 22. You still have six days to register. All three Main Events play their Day 2 on Monday, March 23, the final day of the series.
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.
- $1.5M GTD Multi-Flight ($630 buy-in): flights running through March 23, with Day 2 on March 23.
- Two $500K GTD Mystery Bounty events ($109 buy-in): the format that keeps drawing massive fields across online poker. One mystery envelope can change your entire result.
- $150K GTD Mystery Bounty ($33 buy-in): a legitimate shot at a five-figure score for a buy-in most grinders won't blink at.
- $100K GTD Mystery Bounty ($5.50 buy-in): micro-stakes players can enter for less than a coffee and compete for a real prize pool.
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.
| Tier | Buy-in Range | 1st Place Prize |
|---|---|---|
| High Stakes | $104.50 and above | $15,000 |
| Mid Stakes | $16.50 to $88 | $7,500 |
| Low Stakes | Under $15 | $4,000 |
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.
