Tengri 137 is the name of a mystery game, in the center of which is an encrypted book. The last seven pages of this book still wait to be deciphered.
Encrypted books are one of my favorite topics. I have even assembled a list of encrypted books, which currently contains 83 entries. The latest entry is an untitled book that was created by an unknown author as a part of a mystery game named Tengri 137.
Readers of this blog certainly know Cicada 3301, the most popular internet mystery game. Cicada 3301 started in January 2012 with a new round beginning every year in January. Each round consists of a chain of puzzles, many of which involve cryptography or steganography. It is completely unknown who is behind this strange game and what the purpose of it is. After Cicada 3301 had gained much popularity during the first few rounds, not much has happened in recent years. In January 2015 no new puzzle showed up. Round 5, which started in January 2016, didn’t attract much attention (I’m still not sure whether the puzzles that were posted were genuine). In January 2017, again, nothing happened.
Will Tengri 137 be the new Cicada 3301? We’ll see. So far, the encrypted book mentioned above (published in August 2016) is the only document published by the organizers. It has 23 pages. Here’s a PDF for download. The following figure shows page 7:
Pages 1 to 16 are written in a secret alphabet, which has been solved (it’s a simple letter substitution). Here’s the cleartext of page 7.

More information is availabe on the Tengri 137 Wikia. This site also contains the cleartext of the first 16 pages. According to the Wikia, the decrypted text contains, among other things, the following topics:

- magic cubes with links to Bible verses
- perfect magic circles
- perfect magic squares
- link to cicada 3301 and warning for the cicada solvers
- calculations with up to 57 decimal place primes (7 pages calculation with prime numbers)
The unsolved part
Pages 17 to 23 of the Tengri 137 book are different from the 16 first ones. Here they are:
These last seven pages of the Tengri 137 book contain long multiplications and divisions, the purpose of which is unknown. Do they code a message? So far, the answer is not known.
