Power your brain with a sudoku exercise
Created by an American, Howard Garns, but popularized in Japan in the 1980s, Sudoku is a logic-puzzle that, according to scientists, boosts the brain.

In fact, according to Judy Skatssoon, in her article “Why Sudoku makes your brain ache,” solving Sudoku puzzles “depends on neural pathways that even the most powerful computers can’t replicate."

To successfully complete a Sudoku puzzle, you must enter numbers ranging from one to nine into the blank squares. The 9x9 grid is made up of 3x3 boxes. Every row must contain one of each number, one through nine, as must each column and each 3x3 box.

Each Sudoku puzzle has a unique answer. See if you can find the solution to the one below.

She was a math director at a school for years until she retired at the end of last year. She still loves to do these puzzles often. report abuse vote down vote up

It is so frustrating when you get to the last number and it doesn't fit! I got this one in about 10 minutes. report abuse vote down vote up
