Featuring a huge number of Arrow Sudoku puzzles, all carefully sorted into order of increasing difficulty, this unique collection of 200 puzzles is full of attractively-designed challenges from best-selling puzzle author Gareth Moore, author of many international books. Arrow Sudoku adds multi-square arrows to regular Sudoku. Each arrow starts with a circled square and then crosses a series of other squares which must sum up to the value in the circled square. Often the circled square is empty when you begin the puzzle, so the puzzle solves differently to other numerical variants such as Killer Sudoku. Printed on large, top-quality paper ideal for solving on, the 200 Arrow Sudoku puzzles vary in difficulty from easy to hard so whatever your preference or experience you'll always find a puzzle here to suit you.
