London, Feb 18: A scottish punter's sleep was broken up in the middle of the night by a barking dog, and the man went on to play online gambling to win a record-breaking £5.1million , Daily Mail reported.
The winner - who has decided to remain anonymous - staked just one pound on a slot machine game.
After a few wins in a row on the game, which is like a computer version of a one-armed bandit, he was up £250.
He then moved on to a Betfred game called Beach Life, which has a massive jackpot. After six spins he’d hit the top prize - £5.1million.
He had won the UK's biggest online slot jackpot of all time - and the third largest ever in the world.
The winner is in his 20s and lives in a modest flat in Ayrshire, according to the Daily Record.
His friend told the paper: ‘He obviously found it pretty difficult getting back to sleep after that. It’s just unbelievable.
‘He owes it all to that dog – he’d like to meet it and shake its paw.
‘He is over the moon and just trying to take it all in.’
He added that the winner has gone to stay with a relative while he gets his head round his win and decides whether to keep his story a secret.
Shortly after hitting the jackpot, the newly-made multimillionaire was flown by private jet to meet Betfred.com founder Fred Done, where he was presented with the massive cheque.
Betfred.com was unable to give any details of the winner as he had requested anonymity, but confirmed: ‘One lucky customer has become the biggest online progressive jackpot winner in UK history after scooping the ¬mind-blowing £5.1million jackpot on the Beach Life slot game.’
Done added: ‘As a bookmaker, I get a thrill out of turning someone into a multi-millionaire at the click of a mouse.’
