The object is to fill all empty squares using numbers 1 to 9 so the sum of each horizontal block equals the clue on its left, and the sum of each vertical block equals the clue on its top. In addition, no number may be used in the same block more than once. |

Kakuro Variants Kakuro variants are solved using the same rules as Classic Kakuro. The only difference is the external shape of the puzzle grids. Fill all empty squares using numbers 1 to 9 so the sum of each horizontal block equals the clue on its left, and the sum of each vertical block equals the clue on its top. In addition, no number may be used in the same block more than once. Kakuro Magic Blocks The secret to solving Kakuro puzzles is learning how to use magic blocks – those special situations where only a single combination of numbers can fit into a block of a given length. For example, if 6 is the sum-clue of a block of three squares then the block must consist of the numbers 1+2+3 but not necessarily in this order. |

The only thing left is to find out in which order the numbers should be organized. This Kakuro Magic Blocks table shows all the magic block possibilities which may occur in Kakuro puzzles. |
