Revenge of Killer Sudoku

By D.J. Ape

Revenge of Killer Sudoku - Volume 1: Where the Journey Begins

This is the first book in what would become a 10-volume series - the foundational Killer Sudoku progression that has guided thousands of solvers from intermediate to advanced. If you have completed "Easy Killer Sudoku" and want the next challenge, the Revenge series is the natural step up.

In Killer Sudoku, there are no starting digits. Cells are grouped into cages with sum clues, and you must deduce every digit using sum analysis, the Rule of 45, and standard Sudoku logic. The introduction explains the key techniques clearly, making this accessible even if Volume 1 is your first Killer Sudoku book beyond the beginner level.

The Revenge series then continues through 10 volumes of increasing sophistication, followed by the Deadliest series (5 volumes) and the World's Hardest series (3 volumes) - the most comprehensive Killer Sudoku difficulty progression available.
