i don't think it's fixed - you see the winners on the TV who seem like ordinary people. i don't really understand what you mean by "too good to be true" tho
In what way could it be fixed? The only way I could see would be if the winning ticket is printed off after the winning numbers are pulled out.
But what would be the point in fixing it?
The young couple who used to live across the road from us were part of a 10 person family syndicate that won £1.5 million they both had a share. As the lass said not enough to retire on at 20 but it certainly changed things for them.
