• 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...

• 02 Keyboards

  Sometimes you have a jumble of numbers or characters in front of you as a puzzle, which can be translated into plain text using keyboards. Keyboard shifts and position A variant of the keyboard shifts usually works with a standard QWERZ keyboard - i.e. the one we usually have under our...

• 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, black-and-white 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...

• 01 Manually decrypt ciphertexts

  Simple, monoalphabetic ciphers, where each letter of the alphabet is simply assigned a different letter, character or string of numbers, can be deciphered in a relatively short time using a piece of paper, a table of letter frequencies for the language in question, and a little time. As a...

• 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...

• 04 Binary, octal and hexadecimal numbers

  "There are 10 kinds of people. Those who understand binary code and those who don't." Another, much better known, place value system is the binary system. A place value system with a base of two. There are only two states, zero and one, on or off, dot or dash, there or gone, true or false....

• 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...

  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...

• 01 What are Babylonian Numbers?

  Babylonian mathematics - Wikipedia The Babylonians calculated in a number system with the base 60 (sexagesimal system). That means that the place values are ascending from right to left: 600 (1), 601 (60), 602 (3600), 603 (216.000) and so on. Multiplying the digits by the place value gives...
