The rules are easy to learn : A number above the diagonal line in a black square is the sum of the white squares to the right of it. A number below the diagonal line is the sum of the white squares in the sequence below it. For regular kakuro puzzles, you may only use the digits 1 to 9, and a digit can only be used once in any sequence. In addition, BestKakuro creates puzzles where zeros are allowed in the solution. For these puzzles, you may use any of the digits 0 to 9. As with regular Kakuro puzzles, each digit can only be used once in any sequence.";
