Hitori will be interesting for players of any age. Unlike Sudoku, all numbers are given in the grid. The objective is to eliminate numbers by filling in the squares so remaining cells do not contain duplicate numbers in any row or column. Filled-in cells cannot be horizontally or vertically adjacent, although they can be diagonally adjacent. All the un-filled cells must be connected horizontally or vertically in a single group. This book contains 200 9x9 puzzles, 4 per page. We are sure you will find these puzzles offer an entertaining yet effective way to exercise your brain and keep your mind sharp. All puzzles have been checked to ensure there is only one valid answer. Find more pencil puzzle books on Brainy's website www.BrainysLogicPuzzles.com
