What does a jackpot win look like?
Microgaming have released a video showing the moment a UK player won £2.7m in November 2019 playing the famous Mega Moolah slot.
The largest-ever progressive jackpot won by a UK player was £13,213,838 in October 2015 at Betway Casino - all from a 25p bet!
Jon Heywood from Cheshire had only been a member of Betway for less than 30 minutes before hitting the life-changing win. At 11.37 pm on Tuesday 6th October, he deposited a total of £30 and began to place 25p bets on the slot game 'Mega Moolah'. It took just seven minutes until he hit the jackpot.
While playing the slot, he was watching a TV show on tanks when he thought he had won £10,000. It was only after a phone call came through from the casino manager the next day that he realised what he had won.
The prestigious Guinness World Records later awarded the British Army soldier the "Largest jackpot payout in an online slot machine game" ever following a rigorous approval process.
Jackpots are paid randomly on any spin. Play progressive games with caution as many have lower RTP than regular slots.
If you are ever lucky enough to win a multi-million-pound progressive jackpot at an online casino, you have the option of remaining anonymous. If you do choose to go public, you are often flown overseas to Malta or even Australia where the casino is based for a press conference and plenty of champagne!
