Killer Samurai Sudoku: 100 puzzles - Paperback

by Djape (Author)

Killer Samurai Sudoku Volume 9 - 100 Puzzles Spanning Three Difficulty Levels

Volume 9 of the Killer Samurai series brings 100 puzzles that combine Killer Sudoku's cage-sum logic with Samurai's 5-grid overlapping structure. Three difficulty levels ensure the book serves both intermediate and advanced solvers.

Be warned: even the "easier" puzzles in this series are challenging by normal standards. Killer Samurai requires you to apply the Rule of 45 and cage analysis across five interconnected grids - a format where deductions in one corner can unlock cells on the opposite side of the puzzle.

All solutions at the back. 8 x 10 inch format with comfortable grid sizes. From DJAPE - whose Samurai Sudoku appears in The Washington Post every Sunday since 2006. Over 250 books, PhD in Computer Science.
