What’s the longest session you’ve ever pulled at the poker table?

The Guinness World Record for the longest live session was held for many years by Phil Laak after the man known as ‘The Unabomber’ played for 115 hours. During the marathon game Laak was able to take a 5-minute break every hour, as well as to ‘bank’ unused breaks for slightly longer rests.

Phil Laak got lucky and then unlucky to bust in sixth place, falling short of his first Circuit ring. Laak is still a regular sight at the poker tables.

Laak’s record stood for over a decade, until Zach Gensler topped it in 2021 with a 124-hour session at Resorts World. Gensler played in public, on video, and regularly tweeted during his record attempt, yet for some reason doesn’t seem to have been recognized yet by the official keepers of the world record.

That is likely to be more to do with the record-keepers than the record-setter as, for example, according to the official Guinness World Records site, the current official record for ‘most entrants in a WSOP Main Event’ is deemed to be the 6,494 entrants in 2009 — a number that was surpassed twice before 2009 and has been bettered a dozen times since.
