Sunday has always been the big day on the online poker calendar.
ACRPoker appears to have taken that as a challenge.
The second Sunday of OSS XL arrives on September 13th with more than $4 million in guarantees across the published series schedule, including the opening flight of a $500,000 Main Event, a $600,000 guaranteed tournament, a $500,000 high-stakes event, a $300,000 PKO and the $250,000 guaranteed Mini Phil’s Thrill.
And those are only the headliners.
With buy-ins stretching from micro stakes to $2,650, Sunday’s schedule offers something at virtually every bankroll level.
The $500K Main Event Begins
Perhaps the most important tournament on Sunday’s schedule is one of the cheapest.
Day 1A of the $500,000 guaranteed OSS XL Main Event gets underway on September 13th with a buy-in of just $66.
Players who survive the opening flight will have another Day 1 opportunity on Sunday, September 20th, before Day 2 takes place on September 27th.
For players looking to get in for even less, ACRPoker is running $6.60 satellites into the event.
A $500,000 Main Event for $66 would already be enough to make Sunday noteworthy. It has plenty of company.
$600K and $500K Headline the Sunday Majors
The largest single-day guarantee on the OSS XL schedule Sunday is a $600,000 guaranteed tournament carrying a $630 buy-in.
There is also a $500,000 guaranteed event at the $1,050 level, creating another major target for players at the higher end of the schedule.
Those tournaments sit alongside a $250,000 guaranteed $630 event earlier in the day and a $250,000 guaranteed $215 tournament.
For high-stakes PKO players, ACRPoker has put up a $300,000 guarantee on a $2,650 Progressive Knockout.
That gives Sunday a mix of traditional freezeout-style tournament action and formats where eliminating the player across the virtual table can be almost as important as climbing the payout ladder.
Mini Phil’s Thrill Returns With $250K Guaranteed
One of ACRPoker’s newer high-stakes fixtures is also part of the Sunday schedule.
Mini Phil’s Thrill carries a $2,650 buy-in and a $250,000 guarantee on September 13th.
The event sits below the $10,300 Phil’s Thrill in the operator’s growing lineup of high-stakes Sunday tournaments while still offering the type of buy-in and prize pool designed to attract serious tournament players.
The opening Sunday of OSS XL already produced an interesting Mini Phil’s Thrill storyline when ACR Poker CEO Phil Nagy, playing as Justsomefish72, reached its final table on the same day he finished runner-up in the $10,300 Phil’s Thrill.
This Sunday brings another chance for the high-stakes crowd to take a run at it.
Plenty Below the High-Stakes Level
The September 13th schedule is not simply a wall of four-figure buy-ins.
The $27.50 Sunday Smash comes with a $100,000 guarantee, while an $88 PKO offers $150,000 guaranteed.
There are Mystery Bounty events, traditional tournaments, PKOs and Omaha variants scattered through the day, with buy-ins dropping all the way into the single digits.
That range is an important part of what ACR Poker is doing with OSS XL.
The series may be built around more than $50 million in guarantees and some very large headline events, but players do not need a high-roller bankroll to get involved.
On Sunday alone, the schedule includes tournaments at $1.65, $2.20, $5.50, $6.60, $8.80, $11 and $16.50 alongside the bigger-ticket events.
The Anniversary Tournament Is in the Mix Too
There is even more happening outside OSS XL.
ACR Poker has another regular Day 1 flight of its $2.5 million guaranteed 25th Anniversary Tournament scheduled for Sunday.
The tournament carries a $250 buy-in and uses a cumulative-stack format, meaning players who have already qualified for Day 2 can return to later flights and add another qualifying stack to the chips they have already secured.
With 41 Day 1 flights now on the calendar, the Anniversary Tournament has become another major part of ACR Poker’s September tournament schedule.
More Than $4 Million on One OSS XL Sunday
Add up the guarantees on ACR Poker’s published OSS XL schedule for September 13th and the figure reaches $4,065,500.
That is before trying to package Sunday around a single tournament or a single type of player.
The bigger story is the variety.
There is a $500,000 Main Event available for $66. There are six-figure tournaments for double-digit buy-ins. There are $630 and $1,050 majors. There is a $2,650 PKO. There is Mini Phil’s Thrill. And players can move between traditional No-Limit Hold’em, bounty formats and Omaha variants as the day progresses.
OSS XL runs through September 29th, so there are considerably bigger moments still to come.
For anyone looking for a place to start, however, Sunday, September 13th is difficult to overlook.
