Rules -- Totally Awesum

This puzzle, also known as Kakuro, is often thought of as a Japanese puzzle craze; however, the puzzle was actually invented by Dell Magazines (under the name Cross Sums), an American company, and was adopted by the Japanese puzzle company Nikoli later.

Special thanks to Lomont's Cross Sums for streamlining the process of test-solving and making PNG's for these puzzles.

1. Place a digit from 1 through 9 inclusive in each white cell of the grid.
2. A horizontal or vertical group of consecutive white cells, bounded on both sides by black cells or the edge of the grid, is called an entry. A number in a black cell above a diagonal line represents the sum of the digits in the horizontal entry to its right. A number in a black cell below a diagonal line represents the sum of the digits in the vertical entry below it.
3. No digit may be repeated within an entry.
