When you need a break from Sudoku try Kakuro
The www.sudoku-puzzles.net site includes two other number puzzles besides the standard Sudoku puzzle: Futoshiki and Kakuro.
Kakuro is a little more common, so you might have heard of it. You are given a board ranging in size (on this site) from 5×5 to 10×10. At the beginning of each column and row is a number. All the numbers in that column or row must add up to the number at the beginning. No number can be used twice in one column or row. And the numbers must be single digits. So, for example, if you had a three space row with a 24 at the beginning you would know that the numbers in those spaces had to be 7, 8 and 9. Now you would use the clues from the columns to determine in which order they fit into the spaces.
Tomorrow I will discuss the less well known puzzle game: Futoshiki.
