Quest your way through 60 unique, eccentric and richly illustrated puzzles and brain teasers, requiring you to twist your brain in unnatural ways. No two puzzles are alike and each is embellished with outlandish illustrations. Rich in visual cues and low on explanatory text, the first challenge is figuring out the puzzle objectives. Once solved, each puzzle solution will serve as input for a next enigma. Codex Mysterium is a stand-alone sequel to the successful Codex Enigmatum and offers an interconnected suite of 60 unique and fun brain teasers, allowing for 10-20 hours of puzzle solving, solo with friends or on game nights. The puzzles are accompanied by a bare minimum of instructions (and often none at all). You will need to think out-of-the-box to resolve these brain teasers and combine multiple techniques, including physical manipulation of the book, drawing, folding pages, searching for hidden patterns or visual cues, logical deduction, decryption and much more. The book is fully stand-alone; no apps or internet connection are required. Hints and solutions are provided to ensure you never get permanently stuck.
