$4 Million on the Line: ACR Poker OSS Main Events Build Momentum After Day 1A

Since 2001, ACR Poker has been a cornerstone for reliable, real-money online poker, and their current Online Super Series (OSS) is a perfect showcase of why players keep coming back. Boasting more than $20 million in guarantees across 171 events, the festival just hit its most lucrative milestone yet.

This past Sunday, May 17, the operator dropped the virtual cards on Day 1A of three massive Main Events. With a combined $4 million in guaranteed prize pools in play, grinders are now gearing up for the final week of action.

Because ACR Poker strategically avoided scheduling any series tournaments on Fridays or Saturdays, the Sunday slates are incredibly dense. At exactly 11:05 a.m. ET yesterday, the initial flights for the three OSS Main Events officially commenced.

The high-roller contingent is fighting for a $1.5 million guarantee in the $2,650 buy-in event, while upper-mid-stakes players are targeting an identical $1.5 million guarantee in the $1,050 buy-in tier. However, the true value lies in the $215 Main Event. Featuring a $1 million guarantee, it grants lower-stakes players the rare opportunity to compete for a seven-figure pool without risking a massive portion of their bankroll. 

All three tournaments will run their Day 1B flights next Sunday, May 24, before the surviving fields merge for Day 2 on May 25.

Every deep run this week carries extra weight, as these Main Events feed directly into the overarching OSS Leaderboard races. Funded entirely by ACR Poker, the promotion is giving away $30,500 across two distinct divisions.

• Low Leaderboard (Under $33): Currently dominated by "UNLUKYDUCK82," with "WSTINSON" and "CRAZY 8S" trailing closely behind.

• High Leaderboard ($33 and up): "VASORTFLAM" is holding the number one spot, fighting off "INAUSPICIOUS" and "POTOFGREED."

Players looking to diversify their action outside of the standard freezeout structures have plenty of options. The Mystery Bounty events are already drawing massive traffic, headlined by a $109 buy-in event holding a massive $750,000 guarantee. Budget grinders can also jump into the $33 ($150,000 GTD) and $5.50 ($75,000 GTD) Mystery Bounty multi-flights.

Additionally, players can eye the upcoming $66 Main Event on Sunday, May 24. Starting at 11:30 a.m. ET, this highly accessible tournament features a robust $250,000 guarantee, ensuring the action stays heavy all the way through the Memorial Day weekend wrap-up.
