Killer Sudoku Pro Zero

Featuring a huge number of Sudoku puzzles, all carefully sorted into order of increasing difficulty, this unique collection of 200 puzzles is full of attractively-designed challenges from best-selling puzzle author Dr Gareth Moore, author of many international books. Killer Sudoku Pro features not only cages which must sum to a given value, as in regular Killer Sudoku, but also cages that must multiply, subtract or divide their contents to reach the given clue value. The Zero in the title indicates that all unnecessary cages are removed, so not all squares are covered by a cage. Printed on large, top-quality paper ideal for solving on, the 200 Sudoku puzzles vary in difficulty from (relatively!) easy to hard so whatever your preference or experience you'll always find a puzzle here to suit you.
