One ticketholder has scooped more than £11 million after they hit the National Lottery jackpot.
The lucky winner matched all six main numbers to pocket £11,042,269, Camelot said.
Andy Carter, senior winners' adviser at the National Lottery, described it as "fantastic news" for a single ticketholder to win the "massive" jackpot.
Saturday night's big win means Wednesday's estimated jackpot is £2 million.
The winning numbers were 18, 51, 56, 59, 07, 47 and the bonus ball was 17.
A total of 53 people matched five numbers to win £1,750 each, while 3,622 matched four balls to get £140 each, and 89,452 matched three numbers to win £30 each.
There were no top prize winners in the HotPicks or Thunderball draws.
The winning Thunderball numbers were 35, 30, 33, 24, 01 and the Thunderball was 07.
Mr Carter said: “What fantastic news for a single ticket-holder who has won tonight’s massive £11m Lotto jackpot. This is the second lucky Lotto jackpot winner in October after one player scooped the £2m jackpot in the draw on Wednesday 13 October. Players are being urged to check their tickets and to give us a call to claim this fantastic prize."
It comes after a plumber who scooped £300,000 on a Lottery scratchcard is to swap his wrench for a laptop by retraining as a videographer.
Sean Irwin, of Brentwood in Essex, said he wants to make the most of every opportunity after losing his father to cancer this year.
The 36-year-old bought his winning scratchcard from a newsagent in Brentwood where he went to buy bottles of water for himself and a workmate.
He was left with exactly £3 in change so decided to buy a National Lottery Ruby Doubler Scratchcard.
The scratchcards cost £3 and prizes range from £3 up to the top prize of £300,000.
Mr Irwin said he started to play the scratchcard in his car before returning to the site where he was working.
He said: "I thought I was seeing things, and checked, then triple-checked, I even read the rules on the back of the scratchcard."
Not trusting himself, he drove steadily back to the site and called his boss over to sit in the passenger seat and look at the scratchcard.
"It was a classic moment, there's me and the boss sitting in my little Ford Focus calling Camelot to confirm I'd won £300,000," he said.
"After all the checks the lady at Camelot started singing 'Congratulations' and we both started to cheer, it was flipping brilliant.
"It's been a really tough couple of years, culminating in my dad losing his battle with cancer this summer, and if I've learnt anything from that it is to make the most of every opportunity.
"This win has opened up so many doors and will give me the security to explore a whole new career, so I'm going to do exactly that."
He went on: "The money will give me a bit of freedom to move away from plumbing, so I don't have to rely on the plumbing money coming in.
"I can actually study videography and video editing, get to grips with that, get the right set-up, the right equipment and see where I can go with that."
He said he will also ensure his mother is okay.
"I moved back in with mum and dad a couple of years ago and have stayed ever since," he said.
"The first thing I'm going to do is pay off dad's funeral costs and buy a really lovely headstone too so that mum doesn't have that worry looming over her.
"She's been my biggest supporter so it's the best feeling to be able to now support her a bit.
"I'm also looking to buy a flat, either to live in or as an investment, and then when it's safe to do so again I am off travelling.
"I spent time in Australia and South East Asia so may head back that way, or perhaps I will explore South America instead.
"It's an amazing feeling to know that if I am careful with this money, then the travels I want to do, the career I want to have and the security I need for the long term can all be achieved, and all thanks to £3 loose change."
