"Revenge of Killer Sudoku Volume 8 - Deep Into the Series, Deeper Into the Challenge

By Volume 8 of the Revenge series, the difficulty has settled at a level that experienced Killer Sudoku solvers find both challenging and rewarding. The puzzles require fluent use of the Rule of 45, innies and outies, cage splitting, and combination analysis - applied consistently across every grid.

This is one of 10 volumes in the Revenge of Killer Sudoku series, which together form the core of DJAPE's Killer Sudoku progression. After completing the Revenge series, solvers move on to the Deadliest series (5 volumes) and then the World's Hardest series (3 volumes).

6 x 9 inch format. All solutions included. Every puzzle solvable through logic alone - no guessing. From DJAPE - 250+ books, PhD in Computer Science, Washington Post since 2006.
