What Is the ACR Poker Online Super Series?

The Online Super Series is Americas Cardroom’s annual tournament series. It’s been running for years and has a reputation for delivering massive fields, huge guarantees, and value at every buy-in level.

The 2026 edition is probably the most stacked yet – 171 events, $20M+ in guarantees, three marquee Main Events, and a $30,500 leaderboard competition paid directly by ACR.

One more thing worth noting: no events run on Fridays or Saturdays. Your weekends stay yours.

OSS 2026 Key Facts at a Glance

OSS 2026 Main Events – The Big Money

Three heavyweight Main Events headline this year’s series. Two Day 1 flights run on May 17 and May 24. All three play down to a winner on Monday, May 25.

That’s $4.25 million in Main Event guarantees alone. The $215 buy-in option makes it easy for mid-stakes players to take a serious shot at a life-changing score.

Multi-Flight Events – More Chances to Bag

Not a fan of one-shot tournaments? The multi-flight events give you multiple entries across different days. Bag your chips, come back on Day 2, and play for a massive prize pool.

The $5.50 Mystery Bounty multi-flight is an exceptional value. A $75,000 guarantee for less than the cost of a takeaway? That’s the OSS in a nutshell.

Mystery Bounty Events – Jackpot Poker at Its Best

Mystery Bounty tournaments have taken online poker by storm – and ACR has fully embraced them. Dozens of Mystery Bounty events run throughout the OSS, including dedicated single-day events and multi-flight formats.

When you eliminate a player, you open a mystery envelope. It could be a few dollars. It could be five or six figures. That element of surprise turns every bounty hand into a potential huge win.

Standout Mystery Bounty events include:

• $150,000 GTD MB – $215 buy-in (May 17 and May 24)
• $100,000 GTD MB 6-Max – $630 buy-in (May 17 and May 24)
• $100,000 GTD MB – $109 buy-in (May 17 and May 24)

$30,500 OSS Leaderboard – Get Paid to Play Volume

Play consistently well across the series, and you’ll earn leaderboard points on top of your tournament winnings. ACR pays out $30,500 in leaderboard prizes directly – this is money that comes from the house, not out of your opponents’ pockets.

The more events you play and the deeper you run, the higher you climb. For regular tournament players, this is a free overlay you should be targeting.

Something for Every Stake Level

This is where the OSS separates itself from most online series. With 171 events and buy-ins starting at $0.55, you don’t need a big bankroll to participate. The spread looks like this:

• Micro stakes: $0.55, $1.10, $1.65, $2.20, $2.50 buy-ins
• Low stakes: $3.30 to $16.50 buy-ins
• Mid stakes: $22 to $109 buy-ins
• High stakes: $215 to $2,650 buy-ins

Game Formats Available in the OSS

The OSS isn’t just No-Limit Hold’em. ACR runs a proper mixed-format series, which means PLO players have plenty to play, too.

• No-Limit Hold’em (standard, 6-Max, Hyper Turbo)
• Progressive Knockout (PKO) tournaments
• Mystery Bounty tournaments
• Pot-Limit Omaha (PLO and PLO8 – both 6-Max and full ring)
• Loncar/Boski Daily Double events (pair of back-to-back tournaments)
• Jackpot series events (Major, Minor, Mini)

The Loncar/Boski Daily Double format is a nice touch – two back-to-back tournaments starting 30 minutes apart, giving you double the action in a single session.

OSS Tournament Schedule Overview

Events run across three distinct weeks. Here’s how the schedule breaks down:

May 25 is effectively the Championship Day. All three Main Events plus the $1M multi-flight and $750,000 Mystery Bounty play out to winners. If you only have one day to play, make it that one.

How to Enter OSS Events

Getting into OSS tournaments is straightforward. Here’s how to do it:

1. Create your account at ACR Poker or log in if you’re already a member
2. Make a deposit using Bitcoin, Visa, Mastercard, or another accepted method
3. Open the tournament lobby and filter by “OSS” to see all active events
4. Click “Register” on your chosen event and take your seat

Multi-flight events let you re-enter on different flights if your first bullet doesn’t work out. You can only advance one stack to Day 2, but you can fire multiple bullets to give yourself the best chance of bagging.

Responsible Gambling

The OSS is great fun – but always play within your limits. Americas Cardroom offers responsible gambling tools, including deposit limits, self-exclusion options, and session controls. If you ever feel gambling is becoming a problem, use these tools or contact a support service in your region.
