I've seen this on The Mint for ages ( I think the last bit is 6-5 not 6-1 )
There have been so many guesses and loads are repeated again and again . I don't know if anyone's got it since I last watched a couple of nights ago .
I think it's a complete con . The makers of this programme must be laughing all the way to the bank .
I'm sure they rely on people who've come home from the pub who make loads of calls with practically a zero chance of getting through !
Then in the cold light of day when they're sober , they get their enormous phone bill and realise what an idiot they've been !!!!
There's one born every minute !
