The Durrrr Challenge is the most famous heads-up poker bet in online history, and it ended without a winner. From its launch in January 2009 to a joint settlement video in June 2025, the challenge produced 58,771 recorded hands, a pair of opponents, a Black Friday shutdown and a long, quiet fade. A detailed timeline published by VIP-Grinders this month gives us the cleanest account yet, so here is the history in order, and what it tells us about high-stakes poker.
The offer
In January 2009, Tom "durrrr" Dwan offered to play heads-up against anyone except Phil Galfond. The terms were 50,000 hands, four tables at a time, $200/$400 blinds or higher, in no-limit hold'em or pot-limit Omaha. Dwan put up $1.5 million against the challenger's $500,000. Phil Ivey, David Benyamine and Patrik Antonius accepted. Only Antonius actually played hands.
The structure mattered. By forcing four-tabling over a very large sample, the challenge tested stamina and adaptation as much as raw skill. It also meant that the leader after 50,000 hands would be much less luck-dependent than a single session.
Leg one: Dwan vs Antonius
The first match was pot-limit Omaha, starting on February 18, 2009. The opening session ran 1,541 hands, and Dwan won $134,911. On June 19, 2009, the longest session ran 4,523 hands over about 15 hours, and Dwan closed up about $726,000. The largest pot of the entire challenge, $477,555, went to Antonius.
By October 7, 2009, the match reached hand 25,000, with Dwan ahead by $697,532 after 25,145 hands. Then came the interruption. In November 2009, the anonymous online player "Isildur1", later identified in the source as Viktor Blom, won roughly $5 million from Dwan, which paused the challenge. In the VIP-Grinders timeline, Antonius is also tied to one of the largest PLO pots of that era against Blom on November 21, 2009: a $1,356,946.50 pot at $500/$1,000 on Full Tilt.
The match resumed. In March 2010, Dwan led by $1,986,418 after 33,303 hands. By August 2010 the final recorded tally was Dwan up $2,059,719 after 39,436 hands, with 10,564 hands never played. A buyout was reported but never confirmed.
Antonius later reflected on it. In September 2022 he said on a podcast that he had been overconfident and had not practised four-tabling beforehand. In an October 2026 interview he repeated that he was four-tabling during the Blom session and would "never do that again" in PLO.
Leg two: Dwan vs "Jungleman"
The second leg was no-limit hold'em against Daniel "Jungleman" Cates, beginning in August 2010. On opening night, over 5,829 hands, Cates won $518,191. By January 4, 2011, after 17,108 hands, Cates led by $819,213.50. On April 3, 2011, the last Full Tilt count showed 19,335 hands with Cates ahead by $1,251,059.
Twelve days later, on April 15, 2011, came "Black Friday". US authorities shut down Full Tilt, the venue for the matches. The challenge lost its home.
Restarts and the penalty clause
Between March and July 2013, the players restarted the match and agreed a new schedule, which was not kept. The last recorded session was in October 2013: 1,485 hands, with Cates winning $197,600. The page reports a lead of nearly $1.5 million for Cates, but notes that this is a contemporary report rather than a Full Tilt count.
A 2013 agreement reportedly included a penalty clause. A 2014 trade report gave $40,000 for two months without play, rising each period. Cates said in 2017 that about $700,000 to $800,000 had been paid. VIP-Grinders stresses that neither figure was confirmed by both players, so treat those numbers cautiously.
The settlement
Cates signed with GTO Wizard in May 2025. In June 2025, he and Dwan released a joint video describing the challenge as resolved and their business affairs as settled. Neither gave the terms. Neither leg reached its 50,000-hand target, so neither side bet was decided. The final recorded total is 58,771 hands: 39,436 against Antonius plus 19,335 against Cates on Full Tilt, with about 2,500 further hands against Cates reported in 2013. There is no winner.
One caution from the timeline: the Durrrr Million Dollar Challenge, Full Tilt's live 500-hand event in London in November 2009, was a separate event. People often blur the two.
Why the challenge mattered
The challenge was part marketing, part sport. It gave Full Tilt a flagship story, made Dwan a household name in poker and turned heads-up cash play into a spectator event. It also captured a particular moment: high-stakes online poker at its peak, with unlimited-style bankrolls moving across tables and a community watching hand counts on forums.
It also shows how fragile big-money poker arrangements can be. The match depended on one site, one set of rules and the good will of both players. When the site was shut down and the players disagreed on the schedule, no outside body existed to enforce the bet. In today's market, similar prop bets are more often broadcast, formalized and tied to sponsors.
Lessons for modern players
First, sample size matters. Even 39,436 hands against Antonius left Dwan only about $2 million ahead at $200/$400 and above. Heads-up variance is large, and the leader at 25,000 hands is not guaranteed to be the winner at 50,000. If you track your own results, see our poker odds guide and what is equity for the maths of variance.
Second, table selection and preparation are decisive. Antonius's own verdict, that he was overconfident and unprepared for four-tabling, is a reminder that format familiarity can outweigh talent. Modern players have solver tools, but those can only help if you practise the exact format. Our poker strategy hub covers fundamentals, and the Omaha guide explains the game Antonius and Dwan played in leg one.
Third, bankroll and risk rules matter at every level. Dwan risked $1.5 million against $500,000. Smaller players should follow the same principle in miniature: do not stake what you cannot afford to lose. See our bankroll management page.
What it means for the poker world
The end of the challenge removes a loose thread from poker history. It also underlines how rarely poker's grandest bets reach a conclusion. Today's biggest stories, from high-stakes cash games to million-dollar heads-up matches on streams, are shorter, more transparent and more commercial. The Durrrr Challenge remains the template: a bold offer, a skilled opponent, big numbers, and a public scoreboard.
For readers who missed the era, the details above are the essential record. And for anyone considering a long-running heads-up bet with friends, the lesson is simple: write down the rules, the schedule and the penalties, and agree on what counts as finished.
