## 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. I worked my way through this one by hand, copying the puzzle into a text editor and separating the pairs manually before finally transferring it into RStudio and plotting the result. I moved on. …

## GC4XMN7 RR138 – 404 Found

It’s been a few weeks since I found a puzzle worth programming in R, so I turned back to the RR series in the east of England to see if there was another, and there is. The cache page shows a quite unilluminating image, mostly white with a couple of small characters. Opening the image …

## GC5GRBF RR175 – Polymath

There is a series of puzzle caches in the east of England with a great number of interesting abstract puzzles, some of which are R-able. Amongst this estimable collection is one which is itself a miniature collection of puzzles. I saw it yesterday and starting working on the fifteen small puzzles. As of writing this, …

## GCTV41 Magic Eye View

Remember Magic Eye pictures? It was a craze in the 1990s where you would get books of abstract Pollockesque images, and, using a special technique, you could see a “3D” image. The technique, which I could never properly master, was to see “through” the page, focusing your gaze on a point behind the paper. The …

## GC7X6EW MIND-BENDER

I stumbled upon a nice little puzzle in Gloucestershire, England: Arrange the numbers 1 to 16, so each two numbers next to each other, add up to a square number. (You can only use each number once). Devastatingly succinct. But potentially tricky. I reached out, as I always do, to R to help narrow the …

## GC4F5HY Shredded – JPS09

This puzzle is in Jersey and features an image, which, judging by the colours and rough shape, is obviously a scrambled version of a map of Jersey. The text confirms that a map has been “shredded”, and your task is to unshred it. I’m intrigued to know how they did this in the first place …

## GC6CQT9 Denken tut nicht weh / myślenie nie boli – 06

This puzzle cache is in Mecklenburg-Vorpommern, Germany. The description is in German and repeated in Polish. 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 …
