Kakuro, also known as Cross Sums, involves arithmetic, not just pattern matching.  The objective is to fill the puzzle with digits 1 through 9 so that:

  • The sum of all the digits in a “word” adds up to the total shown above (or to the right of) the word
  • No digit is repeated within each “word”.

Our puzzles are carefully graded by difficulty: Easy, Moderate, Hard and Challenging. Most puzzles are 13×13 but we can generate a variety of sizes from 7×7 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.
