04 Music file analysis
From time to time, there is also something for the ears in the listing. In such media, too, coordinates and further information can be concealed in an outrageously wide variety of ways. The easiest way is in the metadata, which can be found in most music players, in Windows via the file explorer...

03 Technical picture hiding places
Besides the purely optical variants, a lot of nastiness can be done with digital images in a technical way. In geocaching mysteries, I find computerised steganography the worst. As nice as it is to be able to hide almost any imaginable thing in pictures invisibly and almost uncrackable with...

02 Optical game of hide and seek
The simplest way to hide additional information in an image is to simply write it on it in a clearly visible way. If the image has a very high resolution and is therefore displayed at a very small size on the screen, such labelling can be almost invisible, depending on the background. Very large...

05 Esoteric Programming Languages
No, we are not leaving the realm of logic now and entering our inner, spiritual realm of knowledge. Esoteric programming languages might be a little better titled as "exotic" and describe programming languages that were not created for practical use, but for demonstration purposes, as academic...

03 Colours
Many mysteries encode the coordinates with the help of colours. This also has the advantage of making the listing pretty colourful ;) Resistance colour code One of the most frequently encountered is the resistance colour code. Mostly without, but sometimes with calculation of the current...

01 Barcodes
We all know bar codes. For several decades now, the bar codes have been emblazoned on all goods to reveal to the beeping cash register exactly what wants to be bought. With the spread of smartphones, we got another barcode in our everyday lives in the form of the square, blackandwhite data matrix...

01 Monoalphabetic substitution
Monoalphabetic substitution means an encryption in which each letter or group of letters is replaced by exactly one letter, group of letters or character. Thus, there is exactly one key alphabet. The advantage here is the simplicity of encryption and decryption. The disadvantage in the...

06 Painting numbers
After all, in mysteries we are always looking for one thing: the digits or numbers that tell us the GPS coordinates. Thanks to this circumstance, an almost unbelievable number of variants have developed over the course of time to represent numbers. This blog post is about what I consider to be a...

03 Number systems
But what if we leave the pure numbers and number words we know and move into other place value systems? If we no longer count to 10 as in our decimal system (which does not happen to harmonise with the number of our fingers), but perhaps to twenty, as in the vigesimal system. Or to sixty, as in the...

02 Foreign languages
This section thus begins with a topic which would also have fitted perfectly into the section on "Language and Writing". Numbers can be nicely hidden by representing them in foreign languages. One, two, three we will all get freely translated, but what about aon, M?t trà or hai,...

01 Introduction
Numbers are usually what we are looking for. Coordinates. A pair, north and east. Sometimes also a bearing, although here you still need a point from which to take a bearing. Usually this is the coordinate where the listing was placed. If a coordinate is hidden, then either in its entirety and...

Or also: And what do I do with this now??? You've found the puzzle and are now confused by a mountain of numbers, letters, pictures, signs or the like? Again, perhaps this attempt to present in a structured way what what I have found could be will help. Please do not take it amiss if I do not...
