Kakuro is a Japanese logic puzzle, with similarities to both soduko and crosswords. Your aim is to place a number between 1 and 9 in each box, so that the numbers in each run add up to the required total, which is indicated at the top of the vertical runs and the left of the horizontal runs. You cannot repeat a number in a run. You can print out a blank puzzle from the gallery.
