This little tip was posted on another forum awhile back
Of the 2 things presented below you only need solve the letter puzzle on the left
The kerbside numbering which is obscured every now and then doesnt even need to be input.I got this word wrong and another was offered which i got right.
I didnt even enter the number
If you get the letters wrong,which I do 2/3 times in every 10 because their ambiguous
a new one appears
I've only come across one filehost which didnt offer a new puzzle in response to an incorrect guess.
