SUDOKU is the latest mind-boggling, brain-stimulating and highly interesting game, played throughout the world, across all ages. It is generally played on a 9 x 9 board ( having 81 squares). The rules for filling in the numbers are very simple. Each row msut have all numbers from 1 through 9 , each column must have all numbers from 1 through 9 and each small cell ( of size 3 x 3; the puzzle has 9 such small cells) must have all numbers from 1 to 9.

I have added an additional propert to the existing ones – namely BOTH DIAGONALS ALSO CONTAIN numbers 1 to 9.

I have hand-written Sudokus of the following sizes:

Sudoku 10X10 HAVING 10,000 SQUARES,

Sudoku 11X11 HAVING 14,641 SQUARES,

Sudoku 15X15 HAVING 50,625 SQUARES.

Sudoku 18X18 HAVING 1,04,624 SQUARES AND

Sudoku 20X20 HAVING 1,60,000 SQUARES.
