Click n click (GC606J1)

Today’s puzzle is a single part of a mystery that comprises several smaller puzzles, styled on the cult classic TV show The Crystal Maze. To get the coordinates there is a “mental” test for the northings, two easy puzzles that I won’t go into here. The westings are the more interesting part, with a “skill” …

Plotting Pairs (GC4W6HJ)

Planning for a trip to Cornwall, I was churning through some mysteries there, largely picking them at random from the map.

Annoyingly, the puzzle instructions are in an image, so you can’t copy and paste the text into translation software. I retyped the German text into Google Translate and got the gist of it. You have a weighing scales and …
