A third volume of 150 utterly addictive codewords

The concept is simple. Each number represents a letter, so, starting with the solved letters, a player uses their logic and vocabulary to reveal more letters, form words, and then crack the code. The Codeword series is so popular because unlike a crossword, no prior knowledge is needed?players can just pick up a pen and get puzzling. The difficulty slowly grows as they progress through the book expanding their vocabulary, and even though it gives a workout to the brain, it's the perfect way to unwind.
