Introduction to SuDoKu By India Vilas These words are taken from
this Wikipedia page.
The puzzle is most frequently a 9x9 grid made up of 3x3 subgrids (called "regions").
Some cells already contain numbers, known as "givens". The goal is to fill in the empty cells,
one number in each, so that each column, row, and region contains the numbers 1-9 exactly once.
Each number in the solution therefore occurs only once in each of three "directions", hence the
"single numbers" implied by the puzzle's name.

How to play Su Doku ?
The puzzle is most frequently a 9×9 grid, made up of 3×3 subgrids called "regions" (other terms include "boxes", "blocks", and the like when referring to the standard variation; even "quadrants" is sometimes used, despite this being an inaccurate term for a 9×9 grid). Some cells already contain numerals, known as "givens" (or sometimes as "clues"). The goal is to fill in the empty cells, one numeral in each, so that each column, row, and region contains the numerals 1–9 exactly once. Each numeral in the solution therefore occurs only once in each of three "directions" or "scopes", hence the "single numbers" implied by the puzzle's name.
