[Surnetkids] Sudoku Tips

Dear Reader,

I have come to a crossroad. I’m turning 70 in a couple of weeks, and I’ve been writing the Surfnetkids reviews for 27 years. It’s time to figure out what’s next for me, and what’s next for Surfnetkids.com. So, with that goal in mind, I’m taking a June/July summer break from writing weekly updates. Hopefully I’ll find a new way forward that preserves what’s gone before, but gives me more free time.

Thank you all for your years of support.

See ya on the Net,
Barbara J. Feldman

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.

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.
