Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
By the way, I would take off the last two caveats as a recommendation. They appear as needy and unnecessary. Other than that, great job NeilVedwan, and great idea Kirby! A high quality SVG that depicts surrounding areas. Pandora made one as a very kind collaboration with me with a bit ago here. The map is of the same style. I've been starting to get into SVG's using a text editor - A horribly pore and vigorous program that made it take two months to make this hand-drawn map of Europe.
Oh, sorry guys, but this quiz already exists: https://www.jetpunk.com/quizzes/counties-of-england-quiz. It's featured but lower quality, you should ask QM if he could switch out the map.
Not bad, but I think you could be a bit more lenient with some of the answers. For instance, you could accept Kent for Kentish, Devon for Devonshire, Stoke or Stoke-on-Trent for Potteries, Manchester for Mancunian, Lancashire for Lancastrian, etc. Also, I can't figure out why on earth 'Coventry' is included as a distinct dialect on this map but Black Country isn't. The Black Country dialect is one of the most distinctive in the country!
Aghhh, I knew the County Durham one was something with "pit" in it but couldn't remember the exact name. My mum (who's from there) will be disappointed in me.
