SUDOKU!<br />

Sudoku is a logic-based placement puzzle.<br />

The aim of the puzzle is to enter a numerical digit from 1<br />

through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called<br />

«regions»), starting with various digits given in some cells (the<br />

«givens»). Each row, column, and region must contain only one<br />

instance of each numeral.<br />

Completing the puzzle requires patience.<br />

It is re<strong>com</strong>mended as therapy because some studies have<br />

suggested they might improve memory, attention and problem<br />

solving while staving off mental decline and perhaps reducing the<br />

risk of Alzheimer’s disease.<br />
