# Get Started On Kakuro Puzzles

Kakuro, sometimes known as “cross sums,” can become quite addicting to people who enjoy exercising their brains. The puzzle is played on a rectangular grid. Some of the cells - or boxes - on the grid are darkened, and some cells are white. The goal is to fill in the white boxes with numbers from 1 to 9, according to the rules. The numbers you see in the dark cells tell you how to fill in the white boxes. The numbers below the diagonal line refer to the cells below. The numbers above the line refer to the cells on the right. Each number is the sum of the digits in the cells to which it refers.

For example, in the second row of our puzzle, you see the number 3. To the right of that number are two white boxes. The numbers we write in those white boxes must add up to '3.' In one of the white boxes we will write the number '1' and in the other white box we will write the number '2.' 1+2=3. At this point we are guessing which cell gets the '2' and which cell gets the '3.' We will only know for sure when we finish the puzzle.

Numbers in the cells cannot be repeated within the row or column. For example in the first row, fourth column, you can see the number '10.' The numbers in the fourth column must add up to '10.' We have already written a '2.' So could the remaining numbers be '4' and '4?' (2+4+4=10)
The answer is, “No, each number in a row or column can only be used once. “

How about '6' and '2?' (2+6+2=10)
Again the answer is, “No, we can not use the number '2' more than once in the same column.

That leaves only the number pairs '5 and 3,' or '7 and 1.' (2+5+3=10, 2+7+1=10) Again, at this stage, we are only guessing which numbers go in which white boxes. As we fill in other white cells with numbers, we see how they add up. It's very possible - in fact, very likely - that we will have to change some numbers as we go along. This is what makes Kakuro puzzles so frustrating and intriguing at the same time.

Why don't you go ahead and try to finish the Kakuro puzzle we have started here. Some of the numbers may be in the wrong place. As a matter of fact, all the numbers in the white boxes may be wrong. You will only know when you play the game.
