A gambler's winning streak was cut short after he was banned from casinos across Britain after winning £28,000 playing roulette with his 'no-lose' system.
Balvinder Sambhi, from Birmingham, scooped the fortune in just two months using a secret betting pattern which he has spent years perfecting.
But he claims he was so successful that bosses have now banned him from every Grosvenor Casino in the country.
Balvinder Sambhi's biggest single daily win was just over £4,000
Angry Mr Sambhi, 38, said: 'I've never lost with my system and the casinos don't like that.
'They don't want winners in their premises, just losers.
'I used to go into the casino every day and there was never a problem when I was losing thousands of pounds.
'But after using my system to make £28,000 I was taken to one side and told that I was barred. I can't believe it.'

A letter from the director of security of the Rank Group who run Grosvenor Casinos refuses to specify the reason for his ban
Garage owner Mr Sambhi, who does not want to reveal his winning formula, is writing a tell-all book for other punters.
He said: 'Experts have always said that winning at roulette is just down to luck.
'But I've spent years developing a system based on simple mathematics which helps me win every time I play.
'In total, I won £28,000 in two months. Some days I won a little and some days a lot.
'My biggest single daily win was just over £4,000.
'But the fact is I was winning consistently and nobody has ever done that before with roulette.'
But his winning streak came to an end on September 15 when the businessman visited Grosvenor Casino in Birmingham city centre and was told he was barred.
Mr Sambhi said: 'I've been a member of that casino for a decade and have never had problems before.
'I spoke to the manager and pleaded to be told why I had been banned but he refused to tell me.
'I said if they thought I was cheating, or money laundering, then they should call the police.
'But he said that was not the case, so the only conclusion is that I was banned because I was winning so much money.
'Yet my system is not cheating it's all about the maths.'
The Birmingham man has since employed solicitors to ask the Grosvenor Casino chain, owned by the Rank Group, for an explanation.
But the company's Director of Security, John Butler, refused and wrote back: 'You will be aware that we are under no legal obligation to give reasons from excluding someone from our premises.
'It is therefore not my intention to assist your client further.'

A spokesman Grosvenor Casinos, which has more than 30 UK casinos, declined to comment.
Mr Sambhi is now hoping to pass on the secrets of his system in his new book, Sequential Roulette: End Game.
He said: 'People have been playing roulette for hundreds of years, yet no-one's ever come up with a system that consistently wins.
'But I've proved that my system works. Now I want to pass it on to other gamblers so they can win big too.'
