Kakuro is easy to learn! All you do is fill in the blank squares with numbers 1-9 according the the given clues.
Kakuro puzzles will contain many clue squares, these are squares which help you to solve the puzzle. A clue square can have an "across" clue or a "down" clue, or both.
In the example below we see an "across" clue square, with 4 blank squares to the right of it. The 4 blank squares make up a "run", you must fill the run so that all the numbers in it add up to the clue (in this case 13). So you could enter 1,2,3 and 7.
The same is true for "down" clues, however the squares which form the run are positioned below the clue square in that case.
You may not enter any duplicate number in the same run, so the example here is incorrect as it has two 1's. Therefore the combination 1+1+7 cannot be used here to add up to the clue of 9.
So you must fill in every run, using only the numbers 1-9 without duplicates, so that they add up to the clue square given.
You can click the diagonal clue squares to display all the combinations for that run, which makes life a lot easier! Click the clue square more than once to toggle between horizontal and vertical clues.
