Kakuro

The environment enables the user to typeset Kakuro logic puzzles. Enter numbers from 1 to 9 in any order into the blank cells. Here, the given horizontal and vertical sums should result. The zero does not occur. Within a summation, no number can be repeated. Here’s a little self-explanatory example:
