Featuring a huge number of Consecutive 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 Gareth Moore, author of many international books. Consecutive Sudoku uses the same rules as standard Sudoku but adds in a white bar between "all" pairs of squares which contain consecutive numbers, such as 1 and 2, or 8 and 9. If there's no bar, the cells "aren't" consecutive. This simple rule elevates Sudoku to another level, which is why Consecutive Sudoku is one of the most popular variants of all. Printed on large, top-quality paper ideal for solving on, the 200 Consecutive Sudoku puzzles vary in difficulty from easy to extremely hard so whatever your preference or experience you'll always find a puzzle here to suit you.
