Featuring 101 Killer Jigsaw Samurai Sudoku puzzles, sorted into order of increasing difficulty and printed on large, top-quality paper, this second unique collection of such puzzles is full of attractively-designed challenges from best-selling puzzle author Gareth Moore, author of many international books.
Each puzzle consists of 5 overlapping Killer Jigsaw Sudoku grids, 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.
Jigsaw Killer Sudoku combines Jigsaw and Killer Sudoku, replacing the 3x3 regions of regular Sudoku with irregular jigsaw shapes, and adding in the numerical cage constraints of Killer Sudoku.
