It was only the third time they played the game

A couple from Cambridgeshire, UK, who won Friday's £101 million (US$157.7 million) Euro Millions jackpot have been named as Dave and Angela Dawes.
The lucky pair were the only winners of the draw and have claimed the UK's third-biggest lottery prize.
Mr. Dawes, 47, is a shift supervisor at Premier foods while his 43-year-old partner is a volunteer at the British Heart Foundation.
The third time was the charm for the couple — they had only played EuroMillions twice before.
The couple, who have been together for four years, were planning to get married in Portugal next year, so the windfall means they can now enjoy the wedding of their dreams. Angela was a divorcee who opted to take Dave's surname after she met him.
First on the couple's shopping list is a new diamond engagement ring for Angela, followed by a house in Portugal and a Rolls Royce.
A Chelsea season ticket and house near the football team's ground are also on the list for fan Mr. Dawes.
"I'm not worried about getting a box — I want to stand with the real fans and watch my team play," he said.
"I'd also love to live near the ground and have Frank Lampard come over for a cup of tea!"
The couple also plan to give a proportion of the winnings to charity.
Mr. Dawes described how they discovered their win. "We were watching TV and the EuroMillions draw show came on so we kept watching, not thinking we would win anything," Dawes explained.
"We got our tickets out and watched in shock as, one by one, the numbers came up on the line I'd chosen. We couldn't believe it! It was too late to call Camelot so I kept the ticket on me all night until the morning but we didn't sleep a wink."
The biggest-ever Euro Millions prize was a £161 million (US$251.4 million) jackpot won by Colin and Chris Weir, from Largs, Scotland, earlier this year.
The decision over whether to go public after winning such a huge amount has always been controversial. The Weirs were besieged by sackloads of begging letters after they gave television and newspaper interviews and even went into hiding for a while.
