Classic Sudoku Puzzle Books - 400 Easy to Master Puzzles 10x10 (Volume 4)

Classic Sudoku (also known as "Number Place") is a placement puzzle. The puzzle is a 10x10 grid made up of 5x2 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 through 10 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.
