Get hooked on Sudoku

If you feel as if your brain needs a workout, pick up a Soduko puzzle book in your nearest bookstore and get thinking!

Soduko is a logic-based placement puzzle in which you enter a numerical digit from one to nine in each cell of a 9×9 grid made up of 3×3 sub-grids (called”regions”), starting with various digits given in some cells (the”givens”). Ultimately, each row, column and region must contain only one instance of each numeral.

Completing the puzzle requires patience, perseverance and logical ability. Although first publishes in 1979, Soduko initially became popular in Japan in 1986 and attained international renown last year.
