We estimate that Cleveland and Novel are accessible to ages 14+, Ohio and Indoorsy to 12+, and Cryptid to 10+.

Age ranges are primarily based on prior knowledge necessary to solve the puzzles. My opinion is that Cleveland and Indoorsy are the most difficult and Ohio the least difficult. It is a subjective art to age puzzles! Please use your best judgement.

Unfortunately, the first printing of Encrypted Cryptids has one minor error. It is on page 15: "*ΔYβ" should be "*Δλβ".

Ohio Enigmas' first printing had more serious errors. It was sold February through July 2024; if you bought a copy of this book, please reach out via the Contact Form and I will replace it with the updated version for FREE.

Thank you for your patience and continued support of Cleverland Puzzle-- I am not super human and learn a lot each time I produce a new book. I always strive to be error-free and your understanding is greatly appreciated!
