Arrow Sudoku - Gareth Moore - Bog

Featuring 101 Samurai Arrow Sudoku puzzles, sorted into order of increasing difficulty and printed on large, top-quality paper, this unique collection of 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 Samurai 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. Each puzzle consists of 5 overlapping Sudoku grids with added Arrows, arranged so that you must solve all of them simultaneously to arrive at the unique solution to the overall puzzle. Guessing is never needed - only sensible logical deductions. Visit www.PuzzleBooks.org for a full list of other titles in this series.
