I've been doing the cryptograms in this book on & off for quite a while now. I tend to go from one type of puzzle to another - enjoying each type for a month or two, and then moving on to something else. For the last several months, I have been engrossed with Sudoku puzzles (a numbers/logic puzzle), and have only recently moved back to doing cryptograms again...
So, I got out all of my cryptogram books, dusted them off, and jumped right into the fun of decoding again (smile). I had forgotten just how much fun (and sometimes frustrating) cryptograms can be!
"Cryptogram-A-Day Book" is filled with puzzles that, when solved, reveal an interesting quotation, as well as the person known for creating it. It's arranged by date - with one puzzle for each day of the year. It appears that the author's intention was that us cryptogram-lovers would do just 1 of these puzzles per day... However, for me, I just dig right in, and do as many as my spirit moves me to do.
The only reason I gave this book 4 starts instead of 5 is because there are no hints in the back - all you get is the full solution. And, if you're anything like me, your eyes wander and you wind up seeing more of the answer than you wanted. I've become accustomed to the books that offer you 1 or 2 different hints that you can use if you become stuck, before having to go to the full solution.
Overall, I think this is a good cryptogram book, and I really like the fact that many of the solutions are quotes that are inspiring, or lead one to ponder. So, if you enjoy cryptograms, I recommend you give this book a try.
