What's it really like to be a lottery winner?
In 2017, a group of Welsh hospital catering staff handed in their notices after winning a £25,476,778.30 EuroMillions jackpot.
Sian Jones and Julie Amphlett said they still have to pinch themselves. Like most lottery winners, when they saw their lucky numbers they could not believe it.
Both Julie and Sian have bought houses with the money they won and they have also set up some of their relatives for life.
The pair have remained grounded despite their millions and said they still shop in Tesco and still do everything they used to do - apart from their jobs.
They handed in their notices straight after winning. Julie said she worked from the age of 16 so was happy to be able to retire.
Nigel Willets from Caerphilly won just over a million pounds on Friday 13th, 2014.
In Nigel's case, being lucky runs in the family, as his sister has also won the lottery. She won £20,000.
Nigel has used his winnings to start his business, running trampoline parks in Swansea and Cardiff. He has also given money to relatives, paid for holidays to Thailand, Mexico and Florida and treated himself to a new car.
New research has revealed Cardiff is the seventh luckiest place to live in the UK.
The National Lottery has created 103 millionaires in Cardiff since it launched 25 years ago - that's one every three months.
Swansea is the sixteenth luckiest region out of 121.
William and Sophie Richards from Swansea won £1million on the Lotto Millionaire Raffle in May 2018 after Will popped into Asda to buy a tin of mushy peas.
Nigel Willets said winning the lottery does make you a target to conmen or women.
