Shirley, If you Google “Aig tunnel Sudan” you may be presented with what I found. However, the “centre of cells” wording was something that bothered me from the outset and, if I had been under less time constraints, I may have sussed it out. There will be a bit of a postscript in next week’s blog.

Oh dear Dave, I have been staring at your solution and wondering what the AIG was. I decided that bit about the centres of cells was precisely to allow that sneaky walk round the top of London bridge. All in a day’s fun. Just about to start today’s blog as we are travelling to the UK tomorrow – by car, taking a few days. Yours, Shirley

I don’t see how the editors could really justify marking as wrong any path that fulfils the criteria of passing through all the bridges in the right direction and not self-intersecting. The TUNNEL isn’t mentioned or even alluded to in the preamble (it certainly isn’t one of the thematic objects mentioned since it’s not inidcated by a type or famous example; it’s just the word ‘tunnel’). You could pass through the river a hundred times and you’d not have done anything wrong according to the rules as printed.

This moan aside, I thought it was a very nice puzzle.

Shirley, I wondered about the ‘connecting the centres of all cells’ in the preamble to allow a sneaky walk round the top of LONDON. However, I do like my solution!
