I am beginning my journey into Cryptography, having studied a theory-heavy master's degree module, and I have also read The Code Book by Simon Singh, among many other online resources.

What puzzle books would the community recommend, just so I can get into the mindset of code-breaking? I noticed that certain newspapers have puzzles that are just like the Playfair Cipher. This is something that should tilt a little more toward the fun side.

It might be against the rules to ask for specific books, if that is the case feel free to instead answer this question by recommending various types of puzzles.

For classical hand manual cryptography, the book Cryptanalysis: A Study of Ciphers and Their Solution by Helen Fouche Gaines is unsurpassed in my opinion. The exercises are entertaining and of a range of difficulties.

Another book is Elementary Cryptanalysis a Mathematical Approach by Abraham Sinkov. It's a bit more formal in tis approach, but still has enjoyable exercises.
