NO MATH SKILLS NEEDED! Sudoku puzzles are simply logic puzzles; though the more intense practitioners may invoke ideas and methods from combinatorics, or other methods of analysis to help solve the more difficult puzzles. Many varieties of sudoku have evolved over the decades, but the classic puzzle is a 9×9 grid, subdivided into 9 smaller 3×3 grids — and is the type of puzzle provided in this book. The idea is to have all numbers 1 through 9 singularly in each column, each row, and each 3×3 grid. Which means no repeats in a row, column, or 3×3 sub-grid.
This series got started when I got stuck in Cameron, Missouri for almost a week while traveling from New Mexico in September 2016. Getting a few supplies at the local store, in order to hole-up in the hotel while my moving trailer got fixed, on a whim I also purchased a sudoku book from the pulp publications stand while waiting in the check-out line. I had never worked on sudoku puzzles before, but when I got to the hotel room and started fiddling around with the puzzles in the book, I got kinda hooked. When I finally got to my destination, in Illinois, I was toying around with a sudoku puzzle generator on my laptop in a coffee shop while also fiddling around with some sketches and photos on my tablet. A passing customer in the shop was admiring my work and suggested that I should combine the two. So, here you go; the germ of an idea passed on by a random stranger put into action. Enjoy!
We have three editions to choose from. The print editions have one puzzle to a page, i.e. puzzle on one side and blank on the other side to allow for a better coloring experience. There are 50 puzzle/coloring pages. The puzzles range from “Very Easy”, to “Easy”, to “Medium”, to “Hard”, to “Diabolically Difficult”; with 10 of each difficulty level.
What’s a good age range? Probably 13 through adult. Slightly more precocious children as young as 7 years old, or so, may enjoy the “Very Easy” to “Easy Puzzles”. My own son, 7 and a half at the time I bought my first sudoku book, derived satisfaction from the easy puzzles he tried in the book I bought at the store, and was quite good at tackling the puzzles.
