Also known as Cross Sums, this is the puzzle that is predicted to become the “next” sudoku, now that a younger and more male audience has discovered the pleasures of puzzle solving. NumberPuzzles.com has been offering these puzzles since 2002, and is very pleased to see the rest of the world catching on!

Kakuro involves arithmetic, and not just pattern matching. Solvers need to fill the puzzle with digits 1 through 9, so that the sum of each vertical or horizaontal “word” adds up to the specified total, without any repetition.

Our puzzles are carefully graded by difficulty: Easy, Moderate, Hard and Challenging. Most puzzles are 13x13 but we can generate a variety of sizes from 7x7 up to 31 x 31. The grids are symmetrical (180 degree rotation.)

All puzzles are rigorously tested to ensure that they have exactly one solution, which can be deduced by logic alone. Local trial-and-error may be necessary.

We provide puzzles and solutions in print-ready format (EPS, or Encapsulated Post-Script) as well as machine-readable format (XML), and can provide custom content and format as required.

Please feel free to download our samples or contact us with your requirements.

You can find our kakuro puzzles at uClick.com and in Edigrama publications. They are also featured in The Puzzle Society and available for Palm mobile devices.
