Here is a group of the most difficult codes and puzzles in the world, which are difficult to solve even by experts and scientists, from the codes designed by spies through the chase of real life, to the search for buried treasure or even a book written in a strange language that no one on earth knows.

The most difficult puzzles and codes in history

Kryptos

It is one of the mysterious sculptures located at the headquarters of the "Central Intelligence Agency - CIA" in the city of Langley, designed by the American artist "Jim Sanborn" with the help of "Ed Scheidt", where means the word "Kryptos" in ancient Greek (hidden) And it contains four separate codes. It took some CIA agents seven years to decode the first three codes, but the fourth code remained unresolved.

Voynich manuscript

This manuscript is considered one of the most famous puzzles in the history of coding, which is a handwritten manuscript and is believed to date back to the early fourteenth century AD, and it is a book consisting of 246 pages printed on the skin of the calf.

It is written in an unknown language and has nothing to do with European languages, as the alphabet used reaches 28 characters, and punctuation is not used in the text. No one has been able to break the code yet, as some describe this book as an elaborate hoax.

The Beale Papers

Bell Papers is a booklet containing three codes. Only one code was decoded. This code contains letters consistent with the Declaration of Independence of the United States.

The remaining two codes remained mysterious and unresolved, as they are believed to denote the location of a buried treasure of millions of dollars.

LCS35

LCS35 is known as the Lock Clock Puzzle, designed by researcher “Ron Rives” at the Massachusetts Institute of Technology MIT in 1999.

Nobody knows what's inside, and it is estimated that it will take 35 years for mathematicians to solve this mystery.

Dorabella cipher

Compared to some of the most mind-boggling icons on this list, Dorabella icons may look like a child's scribble, but they have remained unresolved since 1897 CE.

It consists of only 87 letters spread over three lines of text, and the English composer "Edward Elgar" composed this encrypted message and sent it to his girlfriend, "Dorabella Benny", but neither she nor anyone else understood the content of the message.

The Tamam Shud Case

Reading like the plot of an edgy psychological thriller, the Taman Shud mystery goes back to 1948, when an unidentified dead man – aka the 'Somerton Man' – was found lying on an Australian beach. In his pocket was a page ripped from a book, marked with the message "Tamam Shud" (Persian for "ended" – note the misspelling in the popular name of the case, which dates back to original media reports of the incident).

The police eventually found the book from which the page had been taken, along with a short cipher, which presumably could provide further clues as to the identity of the man, and possibly how or why he came to be left dead on the beach. Unfortunately, nobody has ever been able to solve the cipher, meaning the Somerton Man remains a forlorn and mysterious John Doe.
