$50 Million OSS XL Gears Up for Another Big Sunday Ahead of Second Mortgage Week

Main Event flights lead the September 20 lineup, alongside a $750,000 guarantee, Sunday Splash, Sunday Smash and a full spread of bounty tournaments. Second Mortgage Week follows on Monday.

Three Main Events lead this Sunday’s OSS XL lineup at ACR Poker. On September 20, the $2,650 and $1,050 editions open with Day 1A, while the $66 tournament returns for Day 1B. Across those three tournaments, $5 million is guaranteed.

Build the rest of your session around bigger guarantees, lower buy-ins or knockout formats. The $50 million-plus series has plenty beyond its Main Events before Second Mortgage Week begins on Monday.

Plan your Main Event flight

Choose your buy-in and starting flight:

Main Event September 20 Flights
Main Event Buy-In	Guarantee	September 20 Flight
$2,650	$2.5 million	Day 1A
$1,050	$2 million	Day 1A
$66	$500,000	Day 1B

The $66 Main Event offers satellites starting at $6.60. Its Day 2 takes place on September 27, so qualifying this Sunday means returning the following weekend.

For the $2,650 and $1,050 Main Events, Day 1B follows on Sunday, September 27. Both move to Day 2 on Monday, September 28, with final tables on Tuesday, September 29. These are multi-day commitments: leave room beyond the starting flight if you plan to play.

More big guarantees on Sunday

OSS XL #215 brings a $750,000 guaranteed High Rollers for $630, while #216 offers $250,000 guaranteed for $215. Earlier on the card, #213H also carries a $250,000 guaranteed High Roller at $630.

At the higher buy-ins, Mini Phil’s Thrill #219 guarantees $250,000, and Phil’s Thrill PLO #220 guarantees $200,000. Each costs $2,650 to enter.

Sunday Splash and Sunday Smash keep it affordable

Sunday Splash #213L pairs a $16.50 buy-in with $75,000 guaranteed. Sunday Smash #217H offers $100,000 guaranteed for $27.50.

Further down the buy-in list, OSS XL #217M has $20,000 guaranteed for $8.80. These give players several ways to build a session around smaller entries while keeping room for the $66 Main Event or a satellite attempt.

Choose your bounty action

The $88 PKO #214 guarantees $150,000. Mystery Bounty options include OSS XL #221 at $109 with $100,000 guaranteed and #222H at $44 with $60,000 guaranteed.

For a smaller entry, Mystery Bounty #222L offers $10,000 guaranteed for $6.60. At the other end, OSS XL #223 combines a $630 buy-in, $100,000 guarantee and 6-max Mystery Bounty format.

There is also extra money available through the OSS XL Leaderboard Competition. Its three buy-in tiers share more than $60,000 in added cash and tickets. Only in-the-money finishes in series events earn points.

First place pays $15,000 in High, $7,500 in Medium and $4,000 in Low. If you are already playing a regular series schedule, check your position in the relevant division as your Sunday results come in.

Second Mortgage Week starts Monday

The high-stakes schedule then takes over with 10 Nosebleed Stakes events across five playing days, with two tournaments on each of those days. Entry prices run from $5,200 to $25,500, spanning No-Limit Hold’em and Pot-Limit Omaha, with 6-max and 8-max formats.

The largest buy-in arrives on Sunday, September 27: a $25,500 NLH 8-Max. Monday, September 28 closes the schedule with a $15,400 NLH 8-Max and a $5,200 NLH 6-Max R/A.

ACR Pros Chris Moneymaker and Alex Foxen, plus CEO Phil Nagy, are expected to compete.

There is a way to follow the decisions after the action ends. The Final Table Replayer lets players revisit completed final tables with hole cards exposed.

For now, the immediate decision is Sunday’s flight. Choose the Main Event that fits your session budget, add the Sunday events you want around it, and check start times and registration details in the ACR Poker lobby before you take your seat.
