$43m slot machine win a 'mistake'
A US woman who thought she had won $43m (£28m) on a slot machine has been told it was a mistake.
The Fortune Valley Casino in Central City, Colorado, told Louise Chavez from Denver the machine had "malfunctioned."
It is now unlikely she will see a penny of the dream jackpot.
When the lights and bells went off, Ms Chavez, who earns about $12,000 a year as a carer, thought she had hit the big time.
"All of a sudden I saw the light come on on top of the machine," Ms Chavez told ABC's Good Morning America.
"I'm like, 'Oh, my God! Oh, my God!' I'd never had this feeling before in my life, never."
However, gaming officials investigating the incident reckon it was probably just an unfortunate computer glitch.
Ms Chavez, who was celebrating her birthday, said all she ended up with was a free room for the night, some food and the original $20 she had put into the machine.
"I put my money in there," she said. "Whatever I won, I should get.
"There are dreams and there are things I'd like to do - helping my family, helping my kids. That's why I'm disappointed.
"My emotions changed from excited, thrilled, to very upset."
The casino said it was the first time they had had such a serious machine error in 15 years of business.
