Connect Squares

This puzzle was inspired by a puzzle in the March 2006 Games magazine. The original version used the digits one through nine in a nine-by-nine grid. Our version uses five-by-five and six-by-six grids, making it much simpler than the original. The challenge is similar to that of the popular Soduku puzzles. Numbers must be arranged in a square grid so that each number appears only once in each row and column. However, the square grid is divided into smaller rectangles, and each rectangle contains a small number. That small number indicates the sum of the numbers that fill the squares making up the rectangle. Thus, unlike a Soduku, which is mostly logic and process of elimination, Connect Squares involves the use of arithmetic.
