250 Kakuro Puzzles

No doubt you have heard of Sudoku. The Japanese brainteaser has exploded across the UK creating a tidal wave of interest in number puzzles. Now Kakuro is here. Kakuro is Sudoku's bigger, tougher brother - also known as Kakro or Cross Sums. In its native Japan it has millions of followers. Although its rules are simple, completing a Kakuro puzzle can be a considerable challenge. This logic puzzle uses numbers and basic arithmetic to perplex. Kakuro puzzles can come in various sizes from a simple 6 x 6 grid through to giant 30 x 30 mindbenders. The basic idea is to fill in a crossword-type grid so that each set of blank squares adds up to the total to the left or above. Only the numbers 1-9 can be used and the same number cannot be used more than once in each set.Ross, Alan is the author of '250 Kakuro Puzzles', published 2006 under ISBN 9781904468257 and ISBN 190446825X.
