Killer Sudoku Puzzle Book for Adults: 400 Medium to Hard Puzzles 9x9 (Volume 1)

By Alena Gurin

Take on 400 Killer Sudoku puzzles that combine classic number placement with arithmetic logic, progressing from Medium to Hard.

Designed for Sudoku fans who are comfortable with the standard rules, this extensive collection offers increasingly demanding puzzles and plenty of opportunities to develop effective solving strategies.

Killer Sudoku follows the familiar rules of classic 9 9 Sudoku: place the numbers 1 through 9 so that each number appears exactly once in every row, column, and 3 3 box.

What makes this variation different? The grid is divided into outlined groups of cells called cages. A small number shows the target sum for each cage. The digits placed inside the cage must add up to that number, and no digit may repeat within the same cage.
