The prize is the 52nd win since we've been following the online jackpot beginning in December 2009. The jackpot is the online variant of the popular land casino prize of the same name. It grows with every spin of the reels, and it is awarded randomly. The jackpot is available on a series of IGT video slots, and can be won on desktop or mobile devices.
The all-time record for the online jackpot is £2,148,947, which was hit in 2013. The average win is £858,440, and is hit roughly every 10 weeks. This win is smaller due to the £1,274,861 hit four weeks ago.
We'll be sure to update this story as details on the win emerge.
