Killer Samurai Sudoku Volume 6 - 75 Puzzles in Three Difficulty Levels
Volume 6 of the Killer Samurai Sudoku series delivers 75 puzzles that combine Killer Sudoku's cage-sum mechanics with the 5-grid Samurai structure. Three difficulty levels - so you can warm up with the moderate puzzles and work your way to the seriously challenging ones.
Each puzzle features five interlocking 9x9 grids with no starting digits. Cells are grouped into cages with sum clues. You must apply the Rule of 45, innies/outies, and cage analysis across the entire Samurai structure - a solving experience that demands both patience and precision.
75 puzzles. 8 x 10 inch format. All solutions at the back. From DJAPE - The Washington Post's Samurai Sudoku author since January 2006. Over 250 published books, PhD in Computer Science.
