Description: 100 Sudoku puzzles and solutions from the creator of MIStupid.com
From the introduction: Sudoku is a logic puzzle game that has been popular in Japan for many, many years. The object of the game is to fill the 9x9 grid so that every row, every column, and every 3x3 box all contain the numbers 1 through 9 without any duplications. Simple to play yet difficult to master, each puzzle has only one solution that can be reached logically without the need to guess. I recommend using a pencil. One wrong move can leave you needing to erase the entire thing. I also recommend caution, as Sudoku can be highly addictive!
