Revenge of Killer Sudoku

Revenge of Killer Sudoku Volume 9 - The Penultimate Challenge

One volume away from the series finale. Volume 9 of the Revenge series delivers advanced Killer Sudoku puzzles that assume mastery of every technique the previous eight books have demanded. The Rule of 45, innies, outies, cage splitting, hidden subsets - all required, all applied in increasingly subtle ways.

After this book, only Volume 10 remains in the Revenge series. Beyond that lies the Deadliest series (5 volumes) and the World's Hardest series (3 volumes). If you have made it this far, the full progression is waiting.

6 x 9 inch format. All solutions included. No guessing. From DJAPE - 250+ books, PhD in Computer Science, Washington Post since 2006.
