Difficult Sudoku Puzzle Book For Adults: Sudoku 10x10 Puzzles (Brain Game Books)

Sudoku (also known as "Number Place") is a placement puzzle. The puzzle is most frequently a 9 x 9 grid made up of 3 x 3 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 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. ============ KEYWORDS/TAGS: block puzzle adult - adult puzzle blocks - block puzzle brain teaser - block puzzle game - puzzle games - puzzle game books - puzzle game adult - puzzle game teen - brain games - brain games for adults - brain game books - brain game books for adults - brain game puzzle books for adults - brain game adult - brain game game - brain game of the day - brain game puzzles
