If you’ve been waiting for ACR Poker’s $50 million OSS XL series to reach its Main Event stretch, Sunday is the day. ACR Poker runs three Main Event flights on September 20 with $5 million in combined guarantees – and each one sits at a different stage of its run.

The two biggest events open for the first time. The $2,650 Main Event carries a $2.5 million guarantee. The $1,050 Main Event adds $2 million. At the low end, the $66 Main Event returns for its second and final starting flight, with a $500,000 guarantee.

Three Main Events. One Sunday. Plenty more action around them.

ACR Poker OSS XL Main Events

Here’s where each Main Event stands on Sunday – and when it wraps up.

The $2,650 and $1,050 Main Events Kick Off

These two main events account for $4.5 million of Sunday’s $5 million guarantees.

• $2,650 Main Event – $2.5 million guaranteed
• $1,050 Main Event – $2 million guaranteed
• Day 1A: Sunday, September 20
• Day 1B: Sunday, September 27
• Day 2: Monday, September 28
• Final tables: Tuesday, September 29

You get two shots to make Day 2. Fire Sunday, and if it doesn’t go your way, there’s another starting flight a week later.

Last Chance for the $66 Main Event

The $66 Main Event is further along. Sunday is Day 1B – the second and final starting flight – with $500,000 guaranteed.

• Satellites start at just $6.60
• Survivors return for Day 2 on Sunday, September 27

A $750,000 High Roller Leads the Rest of Sunday

The Main Events take top billing – but they don’t have Sunday to themselves. OSS XL #215 is a $630 High Roller with $750,000 guaranteed. That’s another major target for higher-stakes players.

Sunday Schedule Highlights

The spread matters. Buy-ins run from $16.50 up to $2,650, so you don’t need to fire the top events to find a real guarantee. Omaha players get their own shot with Phil’s Thrill PLO.

Mini Phil’s Thrill PLO #220 normally runs with no guarantee. For OSS XL, it plays for $200,000 guaranteed.

The OSS XL Leaderboard Race Keeps Running

Every tournament you play also counts toward the OSS XL leaderboards. That means extra value on top of your results.

More than $60,000 in added cash and tournament tickets are up for grabs. A deep run on Sunday can move you up fast – play the schedule, not just one event.

Second Mortgage Week Starts Monday

The high-stakes action doesn’t cool off after Sunday. ACR keeps raising the stakes. Second Mortgage Week starts Monday, September 21, and runs through September 28.

• 10 Nosebleed Stakes events across five playing days
• Buy-ins: $5,200 to $25,500
• Expected in the field: ACR Pros Chris Moneymaker and Alex Foxen, plus CEO Phil Nagy

Even if you’re not playing, it’s one to rail. Big names, big buy-ins, big pots.

Where to Find the OSS XL Schedule

With three Main Event flights, multiple High Rollers and Second Mortgage Week all packed into the next few days, September 20 is one of the key dates left in the series.
