Kakuro Puzzles

Kakuro is a Japanese logic puzzle, which can be vaguely described as a mathematical crossword. The rules are the following - you have to fill all white squares with numbers between 1 and 9, so that all numbers in a string of white squares (horizontal or vertical) are different. Additionally, the numbers displayed on the sides of the grid should match the sum of the numbers filled in their corresponding strings.

The Kakuros below are shared by KrazyDad, a website with thousands of various types puzzle problems.
