The lines of squares running horizontally are called rows, and the lines running vertically are called columns. The grid is further divided by thicker lines into nine 3 x 3 square boxes. The aim of the puzzle is to fill the blank cells with the correct numbers. Each row, column and 3 x 3 box must end up containing all of the numbers from 1 to 9. Each number can only appear once in any row, column or 3 x 3 box. 100 Medium Sudoku Puzzles Handy & Portable 4 x 6 inch Book Layout Easy to read (1 Puzzle per Page) Advanced Solving Techniques Not Required Ideal For Intermediate Solvers Solutions Included
