I discovered this game a few months back and have since plowed countless hours into it. Be careful, if you like crosswords or word scramblers you may get hooked on this one too. I go to WEBSODOKU for all my puzzles. You can solve them online or print them out and take with you on car trips, doctors visits, or while you’re sitting in a boring class.

At first glance Sodoku looks like a crossword puzzle. The aim of a Sodoku puzzle is to enter a numeral from 1 through 9 in each cell of a 9x9 grid. The primary grid is made up of 3x3 subgrids. A few numbers are given at the start of a Sodoku puzzle and its up to you to figure the rest out. Each row, column and subgrid must contain only one instance of each number. Wikipedia has a good write-up on strategy for solving Sodoku puzzles.
