What is a cryptogram puzzle?
Can you please explain what a cryptogram puzzle is in a concise yet comprehensive manner? I'm curious about this type of puzzle and how it differs from other word-based challenges. Is it similar to a cipher where letters are substituted with others? Or does it involve decoding some sort of encoded message? Additionally, how challenging are cryptogram puzzles typically, and what skills are required to solve them effectively? I'm interested in learning more about this intriguing puzzle genre.
