Hacker puzzle

Time to waste on a Friday? For those who haven't already driven themselves mad playing the hacker game ( it has been doing the rounds of the intraweb for a while) here is an infuriating brain-teaser to try.

I got as far as 22, then had to get help to get the penultimate clue. There was a brief hiatus on 19 as well, then all suddenly became clear. The object is to get to 23, whereupon a granny will dance for you.

If you find yourself admitting defeat, the answers are here ...and remember, google is your friend. Swots can do this in under 10 minutes. It took me about 25 which included mild cheating.

I'll be back blogging properly about politics and life soon, though I'll be visiting my family over the weekend so it might be early next week before anything meaty gets posted.
