Reddit reviews The Complete Liber Primus

Welcome! Given the difficulty of this endeavor, many of us welcome help, fresh perspectives, and new skillsets. I'm afraid that becoming familiar with, and making progress with the Cicada3301 puzzle will require a great deal of reading, with many of the resources being in English.

As /u/Matt_RK900 mentioned, this video by LEMMiNO is a great starting place. Not only will it describe the journey on which the puzzle has taken us, but it will most likely instill a profound interest in the puzzle. These four videos by Great Big Story will paint a more detailed picture of what has gone into the progress of this puzzle as well as summarizing the current status.

As /u/jerry_b_o_o said, the book Liber Primus is a vital resource which requires a great many more skills than a grasp on the English language. While many of the translated pages thus far have been in English, there are mathematical puzzles as well as yet-undeciphered puzzles that may not be based in English. For example, there are clues and references throughout the pages that involve image-analysis. Along with a physical copy of the book, I would suggest downloading the pages for various forms of analysis that can be done with a computer.

Please read the wiki mentioned in the side-bar and feel free to ask questions. Cheers!
