Past World Record Jackpots

Colossal jackpot wins on slot machines have become an annual spectacle. Before the astounding December 2023 triumph on the Wheel of Wishes, the spotlight belonged to the Megabucks slot machines in Las Vegas casinos, where players claimed titanic jackpots.

Highlighting Megabucks’ legendary wins, five extraordinary jackpots stand out:

  • $39,713,892 – A young engineer’s fortune at Excalibur on March 21, 2003.
  • $34,955,490 – A Las Vegas City cocktail waitress’s break at the Desert Inn on January 26, 2000.
  • $27,580,878 – A retired flight attendant’s luck at Palace Station on January 15, 1998.
  • $22,621,229 – A 74-year-old retiree’s golden moment at Bally’s Las Vegas on May 27, 2002.

Megabucks Slots in Las Vegas


Megabucks are programmed slots with a colossal progressive jackpot starting at $10 million. These games are exclusive to Nevada and California casinos, and are not playable online.

Surprisingly, it has been almost twenty years since anyone has won over 20 million on Megabucks. This is probably due to modifications to the slot mechanism. On the other hand, the winning frequency has increased, but the biggest jackpots range between 14 million and 17 million.

To find out everything there is to know about Megabucks, go to! You may be interested to learn that Megabucks was the first progressive jackpot slot machine in history. The company International Game Technology (IGT) launched the first slot in the series in 1986. At that time, the in-game jackpot started at 1 million. Later, in 2005, given the success of Megabucks, the mega jackpot was set at 10 million.

WowPot Series

Introduced in 2020, the WowPot series, led by the first slot, Wheel of Wishes, expanded to include around ten captivating games. Each slot offers diverse themes, betting variations, and bonus features. The bonus wheel provides a chance to win one of four progressive jackpots:

  • The Mini: with a jackpot starting at $10,
  • The Minor: with a jackpot starting at $100,
  • The Major: with a jackpot starting at $50,000,
  • The WowPot: with a jackpot starting at 2 million.

A portion of each bet made by players feeds into the jackpots. The pot value then immediately reboots to its original value each time someone wins the jackpot.

Since the series launched in 2020, seven players have clinched the grand WowPot jackpot:

  1. €38,461,200 – won on December 20, 2023
  2. £15,183,085 – won on April 13, 2021

Mega Moolah Saga

The Mega Moolah series, unveiled in 2006, now has over 30 variations playable at online casinos and stands as the internet’s most sought-after progressive jackpot network. From 2006 to date, we’ve seen over 100 players win the jackpot.

Canadians and Europeans emerge as the prominent victors on the Mega Moolah series, claiming prizes that exceed $10 million.

Online Slots in the USA

Contrary to expectations, the largest online casino jackpots don’t originate from the USA. Only two states in the US permit online slots; Pennsylvania and New Jersey. However, stringent limits prevent users from enjoying millionaire jackpot slots.
