Spacing has been expanded between letters as well as between lines to enhance your decoding experience:
Only simple substitution ciphers are used, meaning each letter of any coded message cryptogram has been encrypted with another letter.
There are 3 Hints per cryptoquote puzzle divided on separate pages in front so you won't see but one letter clue at a time. If you get stuck, try using just one at a time for that may be all you need to start cracking the cryptogram.
Solutions for the cryptograms are in two different sections in the back: a section for Odd-Numbered Puzzles, a section for Even-Numbered Puzzles. This way the next sequential numbered puzzle would not be seen accidentally to spoil the decoding fun.
