Sudoku

I recently came across Sudoku and have found it quite addicting. It looks like a crossword puzzle, but with numbers. Since Dave was reminiscing about the daily crosswords in high school I thought I'd mention sudoku. The object is to insert the numbers in the boxes to satisfy only one condition: each row, column and 3x3 box must contain the digits 1 through 9 exactly once. All puzzles can be solved using logic...no guessing needed. Check out the link to the Daily Sudoku site and clear some time in your schedule. The harder ones can take some time!
