The Basic Kakuro Rules

1. Fill in the digits 1 to 9 in the empty white cells

kakuro rules The kakuro grids are divided in white cells, cells with printed numbers and shaded cells (dead cells). You have to fill in the numbers 1 to 9 in the white empty cells. There is no difference between the 6 by 6 grids or the 12 by 12 Kakuros, in both grid sizes the numbers 1 to 9 apply (so no 12 in the 12 by 12).

2. The sum of each horizontal block must equal the printed clue on its left

where to find printable kakuro puzzles The white cells form horizontal and vertical blocks. On the left side of a horizontal block you see a shaded cell with a diagonal line and 1 or 2 clue numbers. For the horizontal white blocks you need the clue above the line. The white cells need to add upto that clue number. In the example on the left you see a white block of 2 cells with the clue '4'. The answers must be a '1' and a '3' (2 and 2 are not allowed, see rule 4).

3. The sum of each vertical must equal the printed clue above it

kakuro puzzles for kids The same applies for the vertical groups of white blocks. Their clue numbers are under the diagonal lines. In our example on the left we have the clue '12' and have filled in a '3' and a '9'. We could also have used a 4 and 8, or 7 and 5. This is dependent in the rest of the puzzle and combines math and logic in the Kakuro puzzles.

4. You can only use a digit once in each horizontal or vertical block

how to solve kakuro puzzles In a group of white cells, be it horizontal or vertical, you may use a digit only once. In our example on the left we have 2 sixes adding up to 12 and this is not allowed. This rule only applies to the white cell groups and not to the horizontal and vertical grid lines (as in Sudoku).
