What Is the Biggest Win on Online Slots?

While online slots are still in their infancy, these digital casinos have distributed major cash. The biggest-ever win on online slots in the United Kingdom ranks at £13.2 million in winnings, and the largest global win on online slots earned $24 million for a Finnish player.

Slot machines, also known as fruit machines, enjoy a cosy place within popular culture. The sights and sounds of these boisterous and simple gambling games easily attract players of all ages.

The invention of the Internet quickly evolved the experience of the slot machine. Online gambling rose alongside the popularity of the World Wide Web. The invention of the Internet’s first random number generator in 1997 helped online gambling advance. This algorithm replicates the experience of a casino, including cashing out real winnings. 

Today online gambling and online slots are experiencing a rapid rise in popularity. The ease of access to slots sites like makes it easy to enjoy your favourite online slots on your computer, tablet, or smartphone. But what is the biggest win on online slots? Read on to learn more. 

Top Five Largest Online Slots Payouts in the United Kingdom

Our friends here in the UK have raked in impressive payouts via online slots. Here are the five largest jackpots achieved by gamblers in the United Kingdom.

  • Gala Bingo: £5.8 million
  • Mega Fortune: £6.2 million
  • Hall of Gods: £6.3 million
  • Mega Moolah, 2016: £7.9 million
  • Mega Moolah, 2015: £13.2 million

5. Gala Bingo, 2016

The year 2016 marked an exciting year for online slot players in the United Kingdom. A Scottish gambler using an Android device hit a progressive jackpot while playing Gala Bingo. The winner chose to remain anonymous but took home £5.8 million. According to limited news coverage of this lucky winner, she decided to travel with her newfound millions and took her kids to Disneyland.

At the time of this Scottish player’s win, she had raked in the largest mobile gambling jackpot in the United Kingdom at the time.

4. Mega Fortune, 2016

An example of another 2016 winner, the Mega Fortune Slot, gave £6.2 million to this lucky gentleman. He had only placed a £1.25 bet before pulling down this thrilling fortune. Little is known about this winner, who also chose to remain anonymous. 

Games like Mega Fortune use a progressive jackpot style, helping you earn even more rewards from a single bet. JeffBet offers several progressive slot games similar to the thrills of Mega Fortune, like the Kingdom of Cash and White Wizard Jackpot.

3. Hall of Gods, 2017

Scotland wins big again in 2017 with the enormous £6.3 million payout on the Hall of Gods online slot machine game. The winner, known only as Neil in this interview, hit the big bucks after spinning only once. This lucky player raked in the all-time third-largest UK online slots jackpot after placing a single £4 bet.  

A huge football fan, Neil planned to purchase season tickets for his favourite team, purchase real estate for loved ones, and, like his fellow Scottish winner, visit Disneyland.

2. Mega Moolah, 2016

Another Android user in 2016 hit the jackpot in playing online slots. The winner, known only as D. P., pulled down £7.9 million playing Mega Moolah

Wisely, this player stayed under the radar and is hopefully living their multi-millionaire dream life. This may be because they learned from the biggest winner in online slots, occurring only a year prior.

1. Mega Moolah (Again!), 2015

There are interesting similarities and differences between the UK’s first and second-largest wins in online slots. Both of these players struck gold via the Mega Moolah slots, which must be very lucky!

Unlike the second-largest winner, the record holder for the biggest win on online slots shared more details about himself and his win. Jon Heywood, a military member, placed the smallest bet on this list to achieve the highest reward. A tiny 25p wager generated an unbelievable £13.2 million in winnings.

Biggest Wins on Online Slots Worldwide

While these United Kingdom wins are impressive, larger online slots payouts have occurred in other places. What was the biggest win on online slots? You might be surprised to learn that many of these wins came even earlier in the brief history of online gambling and slots.

  • Arabian Knights: £16.2 million
  • Mega Moolah: £18.9 million
  • Mega Fortune: £22.4 million

As early as 2011, online slots have paid out generous jackpots. That year a Norwegian player won £16.2 million on the Arabian Knights online slot machine. 

In 2018, another Mega Moolah player hit it big on this popular online slot at the Grand Mondial Casino. This winner placed fewer than 50 bets on a 75p spin before taking home just under £18.9 million. This prize still ranks as the largest Mega Moolah jackpot in history.

The biggest win on online slots of all time globally goes to a Finnish poker player. Taking a break from poker, this player placed a 25p bet for their spins on the Mega Fortune slots. Soon after, this winner raked in £22.4 million.
