Mystery Killer Sudoku Pro: 200 Puzzles, Paperback/Gareth Moore

Descriere

Description Featuring a huge number of Mystery Killer Sudoku Pro 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. Mystery 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 twist or 'mystery' comes in that you have to work out for yourself which of the operations (addition, multiplication etc) applies to each cage. Printed on large, top-quality paper ideal for solving on, the 200 puzzles vary in difficulty from (relatively ) easy to really hard so whatever your preference or experience you'll always find a puzzle here to suit you.
