Sudoku is a logic-based number puzzle that does not involve arithmetic. Although first published in an American puzzle magazine in 1979, Sudoku gained popularity in Japan in 1986 before becoming an international craze in 2005. The goal is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid, without repeating a number in any row, column, or 3×3 sub-grid. After picking up some on tips at the following sites, you can try your skills at the Surfnetkids Daily Sudoku Puzzle ( http://www.surfnetkids.com/sudoku/ ).

Paul’s Pages: How to Solve Sudoku
http://www.paulspages.co.uk/sudoku/howtosolve/
*****
British journalist Paul Stephens explains the Sudoku-solving techniques of crosshatching (eliminating rows and columns), slicing and dicing (a different way to look at crosshatching), and penciling in. When you’ve solved as much of the puzzle as you can using these three techniques, Paul recommends that you “start finding numbers for squares instead of squares for numbers” by applying five rules. He summarizes it all by offering three keys to successful Sudoku solving: total accuracy, completeness, and maintenance.

Puzzle Japan: Keys to Solution for Sudoku
http://www.puzzle.jp/keys/sudoku_keys-e.html
****
Japanese puzzle magazine Nikoli divides their Sudoku lessons into twelve classes. Starting at Beginner’s Class 1, Puzzle Japan provides lots of examples of crosshatching (without labeling it as such.) Their English is rough in a few spots, but the quality and quantity of the animated illustrations make this a great site for visual learners and K-6 students. “Little by little complicated, but don’t worry.”

*****
This eleven-page free PDF ebook from Michael Mepham of the Daily Telegraph requires the free Adobe Reader ( http://www.adobe.com/products/acrobat/readstep2.html ). For solving really difficult puzzles, it introduces methodological analysis and bifurcation, “the technical terms for picking a likely pair of numbers, choosing one and seeing where the number you have chosen gets you.” It is an excellent resource for high-school students and adults, but does make reference to “a couple of slugs of scotch at the pub,” so it may not be appropriate for every audience.
