Notable Categories of Gambling World Records
Let’s explore some major categories of gambling world records and understand what makes them so noteworthy.
Largest Casino Wins
The allure of the slot machine jackpot often captures the spotlight, advertising the life-changing sums one could win. However, several other casino games deserve recognition as well:
- Slot Machine (Land-based): An anonymous software engineer from Los Angeles won $39.7 million on a Megabucks Slot Machine at the Excalibur in Las Vegas in 2003.
- Slot Machine (Online): In 2013, an anonymous Finnish player won just over $20 million playing Mega Fortune on Betsson.
- Blackjack: Over several months in 2011, Don Johnson raked in more than $15 million using perfect strategy in three different Atlantic City casinos, including a remarkable $6 million haul at the Tropicana in one night. Also notable is Kerry Packer, who won 20−40 million at the tables, including around $10 million from blackjack, betting $250,000 per hand.
- Poker: In 2012, Antonio Esfandiari secured the largest single payout in poker tournament history by winning 18.35 million with a 1 million buy-in, involving only 48 players.
- Craps: William Lee Bergstrom, referred to as the “Suitcase Man,” is known for making an estimated $40 million playing craps throughout his life, famously placing a $1 million bet on a single Don’t Pass Line in 1984.
Highest Bets Placed
While high-profile bets don’t always guarantee success, many wealthy individuals have placed astonishing bets:
- William Lee Bergstrom was infamous for entering casinos with suitcases filled with cash. He placed a staggering $1 million on a single dice roll in 1984 at Binion’s Horseshoe Casino in Las Vegas, regrettably losing the bet.
- Terence Watanabe, heir to the Oriental Trading Co., loved gambling and would often bet between 250,000 and 500,000 per hand, totaling $5 million in a single session.
- Ashley Revell took a unique approach: he sold all his possessions and placed a singular bet in Roulette. Following cameras to the Plaza Hotel and Casino in Las Vegas, he wagered $135,300 on Red and successfully doubled his net worth.

Longest Gambling Sessions
While many of us have spent multiple hours at a blackjack or craps table, these individuals have broken records:
- 115 Hours: Phil Laak set a record for the longest continuous poker session at the Bellagio in Las Vegas in 2010, playing for four days and 19 hours with just five-minute breaks each hour. He did this for charity and walked away with only $6,766.
- 60-72 Hours: Archie Karas reportedly gambled nearly three straight days during his incredible ‘Run’ in the 1990s, starting with only $50,000 and ending with an astounding $40 million.
- 24 Hours: In 2016, Kerry Johnson played over 24 hours on slot machines at the Mardi Gras Casino in West Virginia. Notably, during this marathon session, he managed to rob a bank before continuing to gamble — until his arrest.
Biggest Casino Jackpots
Remarkably, none of the top ten biggest casino jackpots have been hit since 2018, with the largest ever won occurring in 2003:

The World Series of Poker (WSOP) is one of the most prestigious tournaments, having produced numerous celebrity gamblers.
In 2023, it broke records by hosting over 10,000 entrants with a staggering prize pool of $93.4million, where the winner took home 2.1 million. Furthermore, the largest online poker tournament, held in 2020 during the COVID-19 pandemic, attracted 5,802 entrants with a prize pool of $27.5 million.
Unique and Quirky Records
In the colorful world of gambling, here are some of the strangest and most unique records ever set:
