Around August, Edinburgh gets busy - very busy. The population doubles. The streets fill up with humanity. Oh the humanity! So much to do and so, so many people, full of passionate intensity. You're a local. You've got your life to be getting on with - and all this unleashed anarchy is getting in the way. You need a break - surely some relief is at hand?
Here's a quiet spot to escape the hordes, to breathe - just breathe - for a second. Come with puzzle and patience and the reward will be a final destination where no tourist will bother you. Just move and turn the tiles around so that the coloured edges match up. As a local, you'll know the castle can't be moved, but all the other tiles are flexible enough to fit each space any way around.
Soon we can switch the weather from 'dreich' back to 'summer', and you'll have your city back to normal. At least until Hogmanay.
