Review of "Pencil Puzzlers," by Steve Ryan

Review of

Pencil Puzzlers, by Steve Ryan ISBN 0806985429

Five out of five stars

 The puzzles in this collection are hard, but in general all that is needed to solve them is persistence rather than mathematical insight. Although the title hints that the puzzles are those of finding a specific path through a maze, that is not always the case. There are puzzles involving letters in words, determining the values of unseen numbers, a crossword puzzle that uses all 26 letters one time and using straight lines to split a diagram into congruent pieces. The puzzles are challenging, and hints are often given a few pages ahead. Answers to all puzzles are included in an appendix.

 Math skills or insight are not needed to solve these puzzles, they are solved using systematic trial and error. Therefore, people of all ages can use this book to sharpen the edges of their brain cells.
