Kropki Sudoku: 200 Puzzles - Softcover

Kropki Sudoku adds circles between squares which indicate two different types of relationship. A black circle marks all adjacent squares where the value in one is double that in the other, such as 3 and 6. A white circle indicates all numerically-consecutive adjacent squares, such as 3 and 4. The initial grids are empty and it's up to you to use the circles - and the lack of circles - to fill-in every square of the otherwise standard Sudoku puzzle!

Printed on large, top-quality paper ideal for solving on, the 200 Kropki Sudoku puzzles vary in difficulty from easy to hard so whatever your preference or experience you'll always find a puzzle here to suit you.
