Like sudoku, there are many techniques in solving a kakuro puzzle. When the simple techniques don’t work, you will need to use a more complicated solving. Basic and advanced methods for solving Kakuro puzzles. This technique works especially well when intersecting a low-sum with a high-sum definition. An empty square that has all its neighbouring squares (either column or row) filled in can easily be solved. simply add together the corrsponding neighbouring .

If the linking square is part of a column clue Interchange column and row in the procedure given above. Step 1 Kakuro puzzles are all about special number combinations. Instead, I will give you a logic without using unique partitions. You can easily convince yourself that you can figure out the values to be filled into the two squares which are circled in the picture alongside. Kakuro Kakuro is a puzzle given on a grid of red and white cells.

As simple as that: The number of free variables is equal to the null space of the puzzle. Kakuro Kakuro is a puzzle given on a grid of red and white cells. In the example here, that row or column is indicated by the red lines inside the ellipses. If you play puzzles using Kakuro Masterit will automatically show you the correct combinations whenever you place your mouse over kaiuro clue square.

The clue in column C reduces becuase of the value already filled in Ch to 4 2. Duplicate numbers You may not enter any duplicate number in the same run, so the example on the left is incorrect as it has two 1’s.

If the description of the method sounds more puzzling than Kakuro, then you might want to first visit one of the earlier tutorials here or here. Simplify using unique tecbniques Some clues have an unique partition.

As soon as you find a block, it can be replaced by a number computed just from the clues. Because 6 is relatively low it will force low digits in the sum representation, and 29 will force high digits in order to sooving these sums using the given number of cells.

How to solve Kakuro

Otherwise, the Kakuro is badly formed, and you are perfectly justified in writing to the puzzle setter telling her so.

Take the simple example which we solved earlier by putting a variable called x in the cell Bd.

The full list of unique partitions upto length five are so important to Kakuro that a case may splving made to hold them in one’s mind always.

Other games for your PC: It is useful to give a name to this kind of logic, because that helps us remember it. However, the only common number in both sets of combinations is 3, therefore the intersection kakkuro must be 3.
