Sudoku! Poem by Naga Vamshidhar Ratakonda

Every Leisurely Man's,
Meaningful Time Killer;
A Sequence Thriller of,
Number Filling Tussle;

A Simple Grid on Paper,
Of Nine Steps High &
Nine Wide Totalling,
Eighty One Tiny Latin,
Cells Layered & Squared;

Nine Sub Squares,
Still Hidden there;
Three in Each Row,
Three in Each Column!

Got to Fill All the Cells,
With Numbers Counting,
One to Nine Randomly;
Without a Repetetion,
Either Top & Down or,
Within Each Sub Square!

Rules So Very Simple,
Play So Much Tricky;
Glued to the Game Sticky,
Forgetting time Quickly,
Sharpens the Mind Swiftly!

Born in Switzerland,
Made its Name in Japan;
Every Magazine Covers,
Favourite Sudoku Game!
