Cryptograms are simple ciphers. One letter or symbol stands for another throughout the entire puzzle. Cryptograms are single solution puzzles.
In Crypto Quotations, the solution is a quotation and its author. To solve, begin by trial and error, guessing at the value of the symbols. Strategies for beginning include looking for short, common words and finding common word patterns. Once you figure out a few letters, it becomes easier to fill in the rest.
In Crypto Themes, the solution is a list of items that share a common theme or category. To solve, begin by thinking of items that fit the theme, and compare those to the patterns of the items in the list. Once the first match or two is made, you will have enough letters to figure out the rest of the items.
