If you’re looking for the biggest online poker stage of the year, ACR Poker has the spotlight ready. The Online Super Series XL (OSS XL) returns Sept. 7–30, 2025, delivering more than $50 million in guaranteed prize pools and a $65,000 leaderboard fully funded by the site.
This is the largest series in ACR Poker history, packed with hundreds of tournaments, massive guarantees, and unique formats designed to keep every type of player engaged from start to finish.
“After heated back-to-back Venom tourneys, the OSS XL feels like the perfect follow-up,” said ACR Pro Chris Moneymaker. “This series offers every type of player a mix of incredible value with a lot of variety. From main events to survivor flips and mystery bounties, plus big guarantees on top, it’s the kind of schedule that gets the whole community fired up. I can’t wait to dive in.”
Main Events Lead The Charge
The spotlight shines brightest on the three main events, each structured with dual Day 1s on Sept. 21 and Sept. 28, followed by Day 2 on Sept. 29 and the grand finale on Sept. 30.
Buy-ins stretch across the spectrum, as high as $2,650 for the high rollers with a $2 million guarantee, $1,050 for $1.5 million, and a $215 option still packing a $750,000 prize pool.
Mystery Bounties And Survivor Flips
Mystery bounty tournaments inject suspense into every knockout, with prize pools ranging from $500,000 at a $109 buy-in to $100,000 at just $5.50.
Meanwhile, survivor flips keep the adrenaline high, offering a $130 buy-in and $150,000 guarantee. Phase 1 plays out from Sept. 17–21, with qualifiers advancing to a do-or-die phase 2 on Sept. 21.
Leaderboards, Reloads, And Variety For All
OSS XL isn’t just for the high rollers, however. ACR has crafted a tiered leaderboard to reward high, mid, and low-stakes players, with $65,000 in prizes up for grabs.
Add in more than 700 tournaments, wide-ranging buy-ins, and satellites for every bankroll, and it’s clear OSS XL is more than a series — it’s the ultimate online battleground.
Reload Your Roll
Don’t miss the OSS XL Crypto Reload Bonus, which is designed to supercharge your stack heading into the action. From Sept. 1–14, existing players who reload with crypto using the code OSSCRYPTO can claim a 50% match bonus up to $2,000.
