Brain Baffling Sudoku

Sudoku is a logic-based number placement puzzle. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes called regions, contain the digits from 1 to 9. Each pad contains puzzles with increasing levels of difficulty—Easy, Medium, and Difficult. Also included are two puzzles each of Double Sudoku and Samurai Sudoku.
Sudoku is easy to learn but a challenge to master. Spend a few minutes familiarizing yourself with the rules of this number puzzle and you’ll be ready for hours of fun.
