Killer Sudoku 10x10 - Gareth Moore - Bog

Featuring a huge number of Killer Sudoku 10x10 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 Gareth Moore, author of many international books. In Killer Sudoku 10x10 the grid is a little larger than in regular Killer Sudoku - now you must place 0 to 9 once each into every row, column and bold-lined 5x2 box. Like in regular Killer Sudoku, there are also dashed-line cages where each cage must sum to a given value but without repeating a digit. The presence of a zero in the sums adds a twist to the usual Killer formula. Printed on large, top-quality paper ideal for solving on, the 200 Killer Sudoku 10x10 puzzles vary in difficulty from easy to hard so whatever your preference or experience you'll always find a puzzle here to suit you.
