The OSS runs three flagship two-flight Main Events alongside one standalone event on the final Sunday. All three multi-flight Mains share Day 1A on May 17, Day 1B on May 24, and Day 2 on May 25.

ACR Mystery Bounties: A Series Trademark That Never Gets Old

Mystery Bounties are part of ACR's DNA and the OSS delivers three levels of them. The Dual Mystery Bounty Venoms just wrapped up in April 2026, producing some of the biggest individual paydays on the platform this spring. The OSS continues that momentum with flights already running at every level.

Event	Buy-In	GTD	Flights	Day 2
Mystery Bounty	$109	$750,000	April 26 to May 25	May 25
Mystery Bounty	$33	$150,000	April 26 to May 24	May 24
Mystery Bounty	$6	$75,000	April 26 to May 24	May 24

The $5.50 level makes this one of the most accessible Mystery Bounty structures in online poker.

Play More, Earn More: $30,500 OSS Leaderboard

The $30,500 OSS leaderboard does not care about your results. It cares about your volume. Points stack automatically from every tournament you enter across all buy-in tiers, so the grinder firing $5.50 flights daily is just as much in the race as anyone else. The previous OSS XL leaderboard paid its top finisher $15,000 on top of regular cashes, with separate High, Medium, and Low tier prizes.

OSS XL March 2026 Results

The March 2026 OSS XL beat its $50M guarantee by $10M, drawing 569,903 entries from 128 countries. The May regular edition runs at a fraction of that scale but the same structure, the same prize mechanic, and the same track record of delivering fields that exceed their guarantees.

Event	Entries	Winner	Top Prize
$2,650 OSS XL Main Event	994	Rushgold	$480,796
$1,050 OSS XL Main Event	2,298	DificilHein	$304,208
