F5 Poker. Everything Poker. Always Refreshing.

ACR Poker’s November Online Super Series is underway with $20 million in guaranteed prize pools, the same headline amount advertised for May’s edition, but across a shorter 143-tournament schedule. The festival began Nov. 8 and runs through Nov. 24, with 77 Day Series events and 66 Evening Series events.

The four Main Events account for $4.25 million of the guarantee and carry buy-ins of $66, $215, $1,050 and $2,650. The $109 Moneymaker Mystery PKO adds a $1 million guarantee and a top mystery bounty worth $100,000.

As reported Nov. 8, the main change for this OSS is the split between daytime and evening tracks, each with its own leaderboard. The combined leaderboard pool exceeds $77,000 in cash and tournament tickets; the Day Series winner receives $7,500 and the Evening Series winner $5,000, with both also earning a ticket to the January NLH Venom tournament.

The November schedule is 28 events smaller than May’s 171-tournament OSS, which ran May 11-25 with more than $20 million guaranteed. The Main Event guarantee mix has also changed: May offered $1.5 million each at $2,650 and $1,050, $1 million at $215, and $250,000 at $66.

May’s two high-buy-in Main Events cleared their guarantees, paying $2.1 million in the $2,650 event and $1.9 million in the $1,050 tournament. At the lower end, the $215 Main Event drew 4,844 entries and narrowly reached its $1 million target with a small overlay, while the $66 event generated a $252,000 prize pool against a $250,000 guarantee.

The new series follows recent scrutiny over remote-access cheating allegations. ACR said Oct. 7 that its investigation found no compromise of its systems, software or official downloads, while the Winning Poker Network’s Game Integrity team reviewed more than 2 million hands linked to devices where MeshAgent had been detected and found no evidence that hole cards had been used. On Nov. 4, ACR made ScreenShield the default for all players across the network; it had previously been available only to selected players or those requesting it through Support.

Separately, Americas Card Room appeared on a Michigan Gaming Control Board list of 45 offshore operators sent cease-and-desist orders in the four months before April 7. Michigan requires operators offering online casino games or sports betting to state residents to hold a board license, and operators that ignore an order can face further civil and criminal enforcement.

The Moneymaker Mystery PKO has daily qualifying flights through Nov. 22, when surviving stacks combine for Day 2 at 3:05 p.m. ET. The $66 Main Event also holds its Day 2 that day, while the other three Main Events return a day later.
